Do I need a pre filter before water softener and RO water purifier?

As we all know, the

water softener

is to soften the water quality and provide better and cleaner domestic water for whole family.

Hard water refers to water that contains more soluble calcium and magnesium compounds. Because of the high content of minerals in the water, the water quality is harder. The more the content, the harder the water quality; such mountain spring water, well water in natural;

Soft water refers to water that does not contain or contains less soluble calcium and magnesium compounds, such as snow water and rain water in nature;

Soft and hard water are generally distinguished by the hardness per liter of water. The hardness less than 150mg/L is called soft water; the hardness greater than 150mg/L is called hard water.

In other words, as long as the calcium and magnesium compounds in the water are reduced, hard water can be softened into soft water suitable for people use.

What is a Pre filter?

The Pre filter is the first coarse filtration equipment for the whole house water. It can filter large particles such as sand, rust, bloodworms etc. It is generally installed at the front end of the household pipeline, so the word “Pre” is called.

The pre filter is usually a “T” type structure. The left and right ends of the upper “one horizontal” are the water inlet and outlet respectively; the lower “one vertical” is the fuselage and the internal filter; the bottom is the sewage outlet, which is controlled by a valve.

Softer Water Professional Knowledge

Soft water makes Life better. We can’t live without water. People use water to do some cleaning and washing every day. Water is very significant to all of us. We rely on the water so deeply, but we don’t really know everything about the water.

What is the bard water?

Water has soft and hard water. In most parts of China, the water had high magnesium ions and calcium ion contenting, which we called hard water, incrustation and the hard water is a trouble maker in our daily life. Under the condition of heating water will precipitate magnesium carbonate, calcium carbonate which can’t dissolve in water. Therefore incrustation is formed day by day.

What can soft water bring to us?

Using soft water can avoid scaling problems of water pipe, spigot, water appliances and floor heating. Moreover, it can reduce heating costs and the usage of cleaning produces.

Why Use Prefilters Necessary for Water Systems？

When you install a new water treatment system in your home, you may actually install more filters than you think. Some of the best water filtration systems on the market have prefilters that allow you to filter your household water before it reaches the main filter media. In this article, we will discuss why we need to install a prefilter? Types of filtration methods useful for prefiltration and the service life of the prefilter.

What are prefilters?

Prefilter is a kind of filter, which can be simply understood as a metal filter screen, the aperture (filtration precision) of the screen is 1um-100um. Usually installed in the tap water in the front of the pipeline, can filter tap water rust or sediment like large particles of impurities, so that the use of water quality is better, is conducive to the health of domestic water, and at the same time to protect the effect of water pipes. Prefilter is the most important process on the inlet pipe before water going into the house for people drinking and living.

Why do we install the prefilters?

The function of the prefilter can be divided into two categories: one is to protect the domestic water pipe; The other is the protection of household water – wade electrical appliances, reducing the cost of maintenance. There are two main reasons for using prefilters. The first and usually the most important point is that the pre-filter can protect the main filter media from damage and degradation. Certain types of filter media are susceptible to damage from certain types of contaminants, such as chlorine or bacteria. A pre-filter can be installed, which is designed to remove those harmful pollutants so that they will not affect the main filter medium. In other cases, the pre-filter is only used to remove some larger and easier-to-capture contaminants so that they will not block the main filter, thereby extending the life of the main filter medium.

The second reason for using a pre-filter is to remove contaminants that cannot be captured by the main filter. Compared with using the main filter alone, this allows the water system as a whole to remove a wider range of contaminants and produce higher quality water.

Advantages

Protect the washing machine, Soft and comfortable clothes.

Protect water heater from scale and corrosion.

The water in the kitchen faucet is clean, washing dishes and cooking.

Shower bath, care for the skin.

Protect the faucet, the water is clean.

Clean water from a washbasin, wash your face & brush your teeth.

What are some common water systems with pre-filters?

Water softeners. Chlorine can be very damaging to the resin beds inside of water softeners, which is why many water softeners will use a carbon pre-filter to remove chlorine before the water is softened. Some water softeners, such as the Hague WaterMax, include a sediment pre-filter to protect the system from large suspended particles.

Reverse osmosis systems. Reverse osmosis (RO) can remove almost every type of contaminant that you can find in water, so why would it need a pre-filter? A pre-filter like a carbon filter can remove the larger suspended and dissolved particles from water before the water reaches the RO membrane, which extends the life of the media. By letting the RO membrane only worry about the smallest contaminants, the media will last much longer because its pores won’t clog as quickly. Many reverse osmosis systems also have a UV lamp pre-filter to take care of bacteria before it reaches the RO membrane.

Removed secondary pollutants produced in the transportation of water conveyance pipeline

Many urban water supply pipelines have not been repaired and maintained for many years, and the inner wall of pipelines will produce a lot of corrosion, sediment and other pollutants. And because the pipes are long, the water flowing through them will be polluted, so this pollution is called “secondary pollution”. The pre-filter can filter out impurities visible to the naked eye, such as sediment, rust, etc., so that tap water back to the quality of the factory. Our Pipeline Ultra Filtration Water Purifier System can handle the secondary pollution problem well.

Soften water quality and prevent scale to reduce the risk of rust

For users, scale is also a problem that must be dealt with. Scale is the main component of calcium ion and magnesium ion, similar to water heater and other heating water appliances scale, and the pre-filter can avoid the combination of calcium ion, magnesium ion and carbonate ion, to reduce scale effect, thereby extending the service life of water appliances. Our Five Stage Under Sink RO Water Purifier with Metal Stand Frame can filter chlorine, hardness, heavy metals, sand, toxins and many other dissolved water impurities through reverse osmosis.

How long the service life of the prefilter?

In theory, there is no fixed life span for the prefilter, which depends on the water quality and daily maintenance during use. If not properly maintained, the product may age, thereby affecting the effectiveness of the application. Normal monthly maintenance can be used for at least 30 years.

If you have any questions about water systems with prefilters, or if you’d like a water system serviced or installed in your home, contact Newfiltration Technology Team for professional solutions.

Why are you need a wall mounted water purifier for your house?

With the improvement of living standards, health is the most valued and most precious thing for people, and a healthy body is the capital. Health will focus on several aspects, especially diet and sleep. Modern people pay special attention to these two points. There is a saying: Illness comes from the mouth. Therefore, modern people are particularly concerned about diet, requiring organic food, no pesticide residues, and drinking pure water, which are all manifestations of improving the quality of life.

Let’s learn about the advantages of our NFT wall-mounted water purifier: 1. Double outlet design, can drink directly, and can wash vegetables; 2. 5 level RO filtration, the precision reaches 0.0001um; 3. Smart display, real-time control of the life of the filter element; 4. It is convenient and quick to change the core, economical; 5. Polymer reverse osmosis technology, with a filtration rate of 99.6%; 6. With UV germicidal lamp, it can be disinfected and sterilized again to avoid bacterial infection, and the sterilization rate reaches 99.8%; 7. Net water and waste water is 1:1, which means to reduce the cost of water; 8. With a child lock function.

Nowadays, most domestic water is tap water. Some people think that tap water is very clean because it has been disinfected by chlorine gas, but they did not expect the following aspects: 1. Impurities such as heavy metals and microorganisms contained in the water; chlorine cannot kill these; 2. Tap water is transported through long pipelines, which can easily cause secondary pollution; 3. Use a kettle to boil water to drink. This can only solve the high temperature killing bacteria, but can not solve the problems of sediment, rust, heavy metals and so on; 4. The residual chlorine in tap water will produce chloroform after high temperature, which is a common carcinogen.

Therefore, drinking tap water directly not only fails to improve, but also brings safety hazards to the body.

What are the harm to people from drinking unclean water for a long time?

Water is the source of life and an indispensable part of the human body.The water in the human body is renewed every 5 to 13 days.If 70%of the water in the human body is clean,then the cells in the human body will be healthy and fresh environment.Otherwise,it is unhealthy.

Nowadays the tap water and well water cann’t be directly drunk because of pollution,so what are the harm to people from drinking unclean water for a long time?

1,Complications of cancer cells;

2,Cardiovascular sclerosis;

3,Diseases of the digestive system;

4,Excessive heavy metals in the body;

5,Other diseases etc.

Nowadays,people requirements for water are getting higher and higher,Paying more and more attention to their health.From the beginning,the water dispenser only has cooling and heating functions without sterilization and filtration,so the current water purifier,are constantly updated.Looking for a safe drinking method that is most suitable for the moment.

What are the functions of the water purifier?

Generally,water purifier have 5 levels of filtration.Let’s take a look at the function of the 5 levels:

The first level:PP Cotton,remove particles,impurities,blood worms and other harmful substances in the water;

The second and third level:Pre-activated carbon,remove residual chlorine and organic impurities,absorb the thought,color and smell;

The fourth level:RO Membrane,remove bacteria,viruses,scale,heavy metals,etc;

The last level:Post activated carbon,remove peculiar smell and improve taste.

The water purifier improves the disadvantages of the traditional water dispenser,and at the same time improves the water quality.With the improvement of living standards,the water purifier will be recognized and promoted by more and more people.

What are the working principles of household Ultrafiltration filters and Reverse Osmosis filters?

Household ultrafiltration filter is the principle of ultrafiltration and also a principle of membrane separation process.Ultrafiltration uses a pressure active membrane to trap colloids,particles and relatively high molecular weight substances in water under the action of external driving force(pressure).And the separation process of small solute particles through the membrane.

The working principle of the household RO filter is to apply a certain pressure to the water,so that water molecules and ionic mineral elements pass through the RO membrane,and most of the inorganic salts(including heavy metals),organic matter and Bacteria, viruses, etc. cannot pass through the reverse osmosis membrane, so that the permeated pure water and the impermeable concentrated water are strictly separated; the reverse osmosis water purifier is a machine that mainly uses the principle of reverse osmosis for water treatment.

RO water purifier is a machine equipment that mainly uses the principle of RO for water treatment.In this highly polluted living environment,RO water purifiers can efficiently purify sewage and provide us with clean and healthy water quality.

[newfiltration]

What is the difference between an Ultrafiltration water purifier and a Reverse Osmosis water purifier?

The main differences are divided into the following aspects:

1.In terms of filtration accuracy

The filtration accuracy of the ultrafiltration water purifier is 0.01 micron, which can filter water rust, silt, bacteria, large suspended solids, etc.;

The filtration accuracy of the reverse osmosis filter is 0.0001 microns, which means that all impurities except water molecules can be filtered, and it was first used in the field of aerospace science and technology.

2.In terms of water output

The ultrafiltration water purifier has a relatively large water output due to its low filtration accuracy;it is also related to the water pressure of the tap water.

Due to the high filtration accuracy of the RO water purifier,the water output is relatively small.Fro example,the commonly used RO of 75G,the water output per hour is about 12L;and the RO of 400G,the water output per hour is about 64L.The larger the gallon,the higher amount of water.

3.In terms of net waste wate

The ultrafiltration water purifier has no waste water and does not need electricity;

The Reverse Osmosis water purifier has waste water and needs to be powered on.The current waste water ratio of the reverse osmosis water purifier is 1:1.

4.In terms of effluent quality

The water filtered by the ultrafiltration water purifier is generally weakly alkaline,and the water contains minerals,also called mineral water.

The water filtered by the reverse osmosis water purifier is generally weakly acidic,and the water does not contain minerals,so it is called pure water.

5.The power of filtration

Ultrafiltration water purifiers rely on water pressure to drive filtration,and generally the water pressure can reach 0.1Mpa,without electricity or power;

Reverse osmosis water purifier relies on the booster pump to provide power to filter.With power,it can bring many intelligent functions,such as various water temperatures,intelligent reminders to replace the filter element,etc.

[newfiltration]

Why is the Table Reverse Osmosis water dispenser on the stage more and more popular?

With the improvement of living standards,people have more and more stringent requirements for the quality of drinking water.With the development of economy,the integrated heating water purifier has gradually replaced the traditional single filter bottle filtration and water dispenser with only heating function.

Traditional filter bottles can only roughly filter out impurities such as stones,sand,pollutants and can’t filter out harmful substances,such as blood worms,bacterial,viruses etc.In the water,now such filtration methods are no longer seen in many areas;

The water dispenser only has a heating function,and can’t filter any impurities and harmful substance in the water.It can only kill a small part of bacterial and viruses through high temperature;when the water dispenser pours water,it will bring in a lot of bubbles,which will carry some bacterial into the bottled water.If the hot and cold water tanks in the bottled water dispenser are not washed for three months,bacteria,viruses,sedimentation residues,heavy metals,and even blood worms will multiply,which will seriously endanger people’s health.

The desktop integrated multifunctional heating and purifying water dispenser not only solves the problem of incomplete water filtration, but also solves the problem of water circulation heating.The ordinary above counter heating water dispenser has five levels of filtration:

Reverse Osmosis filter membrane:filter out scale and heavy metals,the filtration progress is 0.0001um;

PP cotton and actives carbon conform to the filter membrane:filter out the remaining sediment,rust,sand,red insects and other impurities in the water;remove the residual chlorine in the water,and absorb the different colors and odors;

Rear composite carbon rod:further enhance the taste.

Considering the problems of filtration grade and water quality,traditional filter bottles and drinking fountains are not enough to meet people’s needs,and reverse osmosis water purifiers are gradually replacing old–fashioned water purifiers.

The difference between RO reverse osmosis water purifier, UF ultrafiltration water purifier and ultraviolet water purifier

When we think of "dirty" water, we first think of water-borne diseases. But it has always been pollutants, such as arsenic, lead and other toxic particles, which may be fatal in the long run. In this case, the best way is to install a water purifier at home to remove harmful particles and solvents, and bring clean water to your family. You can choose a combination of UF purifier, UV water purifier, reverse osmosis water purifier or ultrafiltration and reverse osmosis water purifiers. For most of us, trying to distinguish between them can be confusing.

What is an ultraviolet (UV) water purifier?

One of the basic forms of filtration of UV water purifiers is the use of UV radiation to kill bacteria. Force the water to pass through the UV pipe and be exposed to radiation. On the positive side, UV technology is chemical-free and easy to maintain. Unfortunately, it cannot reduce TDS, nor can it filter bacteria that radiation manages to kill. Dead creatures continue to exist in your drinking water.

What is RO (Reverse Osmosis) Water Purifier?

RO water purifier is called reverse osmosis water purifier, which is considered to have good purification effect on the market. The water purifier applies force along the concentrated water area, which flows through the semi-permeable membrane to produce pure RO water. This process can not only simply eliminate harmful particles, but also remove dissolved solids (TDS value), thereby converting hard water into soft water, suitable for consumption. It is equipped with pre-filter (PPF), precipitation filter, carbon filter and RO membrane, etc., to ensure that natural minerals and nutrients maintain a healthy lifestyle while eliminating only harmful elements.

If your water is hard and has TDS, it is wise to buy an RO water purifier.

What is UF (ultrafiltration) water purifier?

UF technology is known as a good form of filtration. It can work without any electricity and eliminate suspended solids, larger particles and molecules from the water through a hollow membrane. This water purifier can kill and eliminate bacteria and microorganisms, but will not remove dissolved solids. It can't convert hard water into soft water, which is what RO water purifier can do to provide you with clean RO water.

[newfiltration]

How does RO filter work?

1. Basic concept of RO filter

(1) Water inlet: Water inlet is marked on the far right side of the figure above, which is usually water that has been preliminarily filtered (in order to prevent clogging, the raw water usually passes through the pre-filtered carbon rod and PP cotton filter element before entering the RO membrane) , Which contains impurities such as ions, organic matter, and microorganisms. (2) RO membrane: The white cylinder in the middle is the main place where the incoming water is filtered. Its structure will not be expanded here in detail, and it will be described in detail in Part 3. (3) Concentrated water: The gray-blue part on the periphery of the blue tube on the left side of the figure refers to the water containing impurities, which is what we often say, the waste water produced after RO reverse osmosis filtration. (4) RO reverse osmosis water (pure water): the water in the blue tube on the left side of the picture, here refers to the water without any impurities filtered by the RO membrane, also called pure water.

2. Pressurized reverse osmosis + RO membrane filtration

(1) Pressurized reverse osmosis: When the water purifier is working, the incoming water containing impurities will enter the RO membrane part of the white cylinder in the middle from the gray-blue part on the right side of the figure. One thing to note here is that in comparison, RO reverse osmosis water (pure water) is a low-concentration solution, while the incoming water is a high-concentration solution. Generally speaking, the flow of water is from low concentration to high concentration, but if a pressure greater than the osmotic pressure is applied to the concentrated solution, that is, the side of the water, the permeation direction will be opposite, and the flow will start from high concentration to low concentration , So you can get purified water, this process is called reverse osmosis.

(2) RO membrane filtration: Here you can imagine it as an extremely small sieve, which can sift out all impurities except H2O. Since the filtration accuracy on the RO membrane (pore size is) can reach 0.0001 micron, (equivalent to) one millionth of the hair, ordinary bacteria and viruses are 5000 times of it, so all kinds of viruses, bacteria, heavy metals, solids Soluble matter, contaminated organic matter, calcium and magnesium ions, etc. cannot pass. Therefore, the water flowing out of the RO reverse osmosis water purifier can be consumed directly.

[newfiltration]

What is RO filter? Basic overview of RO filter

RO filter is a separation method that separates the solute in the solvent from the solvent without resorting to the selective retention of a semipermeable membrane under pressure driving

RO filters have been widely used in the purification and shrinkage of various solutions. A common application example is in the water treatment process, using reverse osmosis technology to remove impurities such as ions, bacteria, viruses, organic matter, and colloids in the water. Obtain high-quality purified water.

　　 Reverse osmosis pure water preparation system uses tap water as raw water, first undergoes pre-pretreatment (softener is optional), and then undergoes RO reverse osmosis treatment. After a series of treatments, harmful substances such as particles, colloids, organic impurities, heavy metal ions, bacteria, viruses, heat sources and 99% of dissolved salt can be removed from the water, and the system's desalination rate is as high as 96-99%. Make the effluent conductivity ≤10μs/cm.

　　The by-product of discharge---concentrated water is environmentally friendly, and it is a separation technology that meets environmental protection requirements.

　　 There is no need to consider the stability of the influent water quality too much. The water quality of the reverse osmosis system can be kept stable for a long time without consuming any renewable materials. This is one of its important characteristics.

[newfiltration]

Talk about the prefilter in detail

The central prefilter, also known as the waterway protector, is an integral part of the home's infrastructure and is generally installed during renovation. The front is a water purification product with a relatively high energy of 90μm. It is an impurity filter device that can filter 40-120 microns of particulate impurities and restore the water quality to the standard of the water plant. It is usually installed after the water meter to any place before the front faucet of the house. The exposed water can reach 90μm. It can ensure that the water supply is relatively high and can reach 90μm. The large amount of precipitated impurities produced in the net will not cause harm to the human body and cause water damage. Wading equipment with relatively high energy up to 90μm and installed on water with relatively high energy up to 90μm, such as water softeners, expert Gu Jiu Chuanzai "machines, pure water machines or direct drinking machines, solar water heaters, electric water heaters, gas water heaters, washing machines, etc. Play a positive role in pre-protection.

　　The basic front is composed of three parts: filter valve, filter element and filter housing. Although the three components seem simple, they contain mysteries that are unknown to the public.

　　 Filters First take the filter valve as an example. The filter valves on the market currently have three materials: copper, stainless steel, and plastic. Copper and stainless steel are actually similar in material and both belong to metals. In terms of mainstream copper materials, copper is divided into national standard copper and recycled copper. Consumers can distinguish by color. The color of high-quality national standard copper is red, while the color of inferior recycled copper is black due to excessive heavy metal content. Some companies will use chemical pickling to remove the black, usually pickling the recycled material Copper shines like gold. The inferior recycled copper will undoubtedly increase the content of heavy metals in the water due to excessive heavy metals, causing harm to the human body.

　　 followed by the filter element, the filter element is composed of a silicone cover and a stainless steel filter. Among them, the stainless steel filter is the core component of the entire front, and the quality of the filter will directly affect the front filtering effect. Generally, the industry uses 304 stainless steel as the material of the filter. Meigu takes the lead in the industry to adopt the higher cost but better quality 316 stainless steel, which has outstanding advantages in terms of service life and filtering effect.

　　 After comparison, it is the filter housing, which is also called the filter bottle in the industry. The filter bottle is also divided into transparent and opaque. If it is opaque, the state of the filter is often invisible, and it cannot be cleaned properly. Transparent filter bottles can be divided into four colors: blue, green, yellow, and white, and their quality and price decrease in order. The transparent blue filter bottle can meet European standards, and it has many characteristics such as antibacterial and anti-riot. For example, Germany's Beishi has a full range of transparent blue filter bottles. The white and transparent, and some white and impermeable filter bottles are made of low-quality or recycled plastics, which may even cause the risk of bottle explosion over time, posing a safety hazard at home.

The main function of the prefilter is to remove the visible solid impurities and some harmful chemical substances in the relatively high energy reaches 90μm, mainly including rust, sand, algae, colloid, etc., and the relatively high energy reaches 90μm, faucet, electrical appliances, etc. Active protection. Moreover, another major feature of the front is easy to maintain. A stable quality front can be used for 50 to 70 years, during which only regular cleaning is required for maintenance. Due to the simple structure, cleaning only needs to open the valve and use the pressure of tap water to flush the filter screen.

Advantages and disadvantages of prefilters

I believe that many people have seen prefilter videos on the Internet, and many families have installed prefilters. In fact, pre-filters can only filter initially. For families who want to drink directly, there are many disadvantages, but there are also many advantages. Let's take a look at the advantages and disadvantages of prefilters !

Advantages of prefilter:

The prefilter element is not used for half a year or one year like other filter elements. The pre-filter can be removed and washed regularly, and then reused, generally ten or twenty years is no problem. Part of the prefilter even has an automatic flushing function, you don't need to remove and wash manually, it will be flushed regularly by itself. It can also solve the problem of excessive water pressure in the water purifier, and avoid damaging the filter element of the water purifier when the water pressure surges. The suitable water pressure for a general household water purifier is in the range of 0.1 to 0.4 MPa, which is too large or too small None of the water purifiers work properly. In addition, the prefilter can also protect the water safety of other household appliances, such as high-end faucets, washing machines, water heaters, toilets, etc. at home.

Disadvantages of prefilter:

The first point is that the prefilter basically discharges waste water, so you must know this problem when installing, and reserve the waste water pipe in advance, otherwise it will not be used later; the second point is due to the prefilter The filter adopts the filter method, which is installed at the water inlet of the home, which will have a certain impact on the water pressure of the home.

The backwash prefilter penetrates from the inner wall of the filter screen to the outer wall through the pressure of tap water, and the particulate impurities such as sand, rust, etc. are trapped in the pipe. Open the flush valve and the impurities trapped by the filter screen are washed away by the water. The water quality is relatively poor, and consumers don’t need to worry about it if they don’t rinse for a long time. Through the backwash switch, the piston runs to the lower part, and the direction of water flow is changed to "external pressure". The impurities embedded on the surface of the filter element and cannot be washed away by the forward flush are washed away by the reverse running water.

Compared with the previous products, the backwash prefilter has a great improvement in technology. The structure is reasonable. The water inlet and outlet can be rotated at any time. The installation is convenient. The front body of the water pipe in any direction can be installed vertically; the flushing design Reasonable "forward and recoil as you wish" will completely flush out the impurities and prevent secondary pollution caused by accumulation of impurities. The most critical point can be as low as 5 microns in accuracy.

Do I need to install a prefilter for domestic water? If you think it is necessary to install the prefilter, you can install it. After seeing the advantages and disadvantages of installing the pre-filter, I also give you a clearer answer on whether to install the prefilter, all according to your daily routine Life needs to choose.

Preventive measures and maintenance methods of prefiltration filter

Many owners have purchased  prefiltration filter and are very aware of the health benefits of water, but only a few people know how to properly maintain pre-filters. 

Today, I will popularize this knowledge for everyone, and the specific introduction is as follows 

1. Equipment antifreeze measures:   

The room temperature for indoor installation should not be lower than 0 degrees, because the volume of water will expand during the solidification process. If it freezes, it will directly cause the pre-filter tube and filter bottle to burst and cause leakage. If it is installed outdoors, anti-freezing measures must be taken. If there is no anti-freezing measures, the pre-filter may crack and the pre-filter must be stopped below zero. If you do not use the pre-filter for a long time or you need to go out, you must close the water inlet valve, drain all the water in the filter bottle, and check the appearance of the machine before normal use.   

2. In the case of icing treatment:   

The entire water purifier should be placed in a naturally thawed room at room temperature above 10°C for 48 hours, in order to continue to use water during this period, and cannot be forced to pass through the water filter to completely check for water leakage after thawing.   

Other equipment protection: avoid direct sunlight, no matter what kind of water purification equipment, you must pay attention to avoid direct sunlight when using the sun to grow algae. Technicians remind the public to properly protect the front filter. If you need to place it in the sun or other places where it may be exposed to direct sunlight, it is recommended to cover a sunshade or baffle near the pre-filter to prevent algae.

How to choose a water purifier?

You can't buy a water purifier blindly. You can consult a more famous brand in the market, and their customer service will be happy to help you. 　　 

Generally speaking, if you want to buy a water purifier, you have to understand the water quality of your home, how many uses you want, and what is your budget? 　　 

1. Look: Fill a glass of water with a glass, look at the light to see if there are any fine substances suspended in the water, and then let it stand for three hours to observe whether there is sediment at the bottom of the cup. If there is, it means that the suspended impurities in the water are seriously exceeding the standard.

2. Smell: Take a glass of water, and then smell it with your nose. If you can smell the bleach (chlorine), it means that the residual chlorine in the tap water exceeds the standard. 　　

3. Product: Taste plain boiled water. If there is astringent taste in the mouth, it indicates that the hardness of the water is too high. 　　 

4. Check: Check whether there is a layer of yellow stain on the inner wall of the kettle at home? If there is, it also indicates that the water hardness is too high (the content of calcium and magnesium salts is too high) 　　 

What types of water purification equipment are there? 　　

1, pre-filter 　　

Main function: filter the secondary pollution of municipal water supply, including rust, sand and algae, the first pass of home water purification! 　　Advantages: protect the wading equipment and pipelines at home, such as all faucets, water pipes, water heaters, etc.; the initial investment is low (a few hundred to 2k), and the subsequent maintenance is almost zero cost. 　　 

Disadvantages: Coarse filtration, limited by filtration accuracy, cannot filter small suspended particles. 　　 

Suitable for the crowd: Most families are worth buying because there are few places with good water quality! 　　 

Note: The filter screen accuracy of the pre-filter is not as high as possible, generally from 50 microns to 100 microns, too high accuracy will affect the water pressure in the home. 　　

2. Whole house central water purifier 　　

Main function: remove large suspended solids, residual chlorine and peculiar smell. Deep protection pipelines, internal pipelines of wading electrical appliances, and high-end sanitary ware; 　　

Advantages: higher filtration accuracy and deeper filtration than pre-filter; larger filtration capacity, generally 0.5 to 1.5 tons/hour. 　　 

Disadvantages: The price is more expensive, the volume is larger, and special space is required. 　　

Suitable for people: people who have extremely high requirements for the quality of living water; there are many high-end wading equipment in the home such as water softeners, dishwashers, boilers, smart toilets, etc.; larger units such as villas and bungalows. 　　 

Note: This type of volume is not small and can be placed in the reserved equipment room. For this type of customer, the brand will be very considerate.

3, direct drinking machine 　　

Main function: High-precision multiple filtration, direct drinking 　　

Advantages: The most high-precision filtration equipment at home, small size, easy to install, RO reverse osmosis membrane can be directly consumed. 　　 Disadvantages: The water output is relatively small, but it can satisfy the family drinking water. 　　

Suitable for the crowd: It can be said that it is standard for ordinary families. Everyone knows what level of tap water is. Children's health is too important!

Note: The filter element must be replaced regularly, pay attention to the water quality reminder of the machine and the reminder of the replacement element.

RO: What is this all for?

Reverse osmosis: referred to as RO, is a membrane separation technology developed in the 1960s. The principle is that raw water passes through the RO membrane under high pressure. The solvent in the water diffuses from high concentration to low concentration to achieve the purpose of separation and process purification. And concentrate. Because it is opposite to the direction of natural penetration, it is called reverse osmosis. RO filter can remove bacteria, viruses, colloids, organic matter and more than 98% of soluble salts in water. The method has low operating cost, simple operation, high degree of automation, and stable effluent quality. Compared with other traditional water treatment methods, it has obvious advantages and is widely used in various industries related to water treatment.

Five. Ion exchange

Various inorganic salts in water are ionized into cations and anions. When the equipment passes through the hydrogen ion exchange layer, the cations in the water are replaced by hydrogen ions. This is the principle of desalination of the cation bed.

Various inorganic salts in water are ionized into cations and anions. When they pass through the OH-type ion exchange layer, the anions in the water are replaced by oh ions. This is the desalination principle of the anion bed.

Mixed bed is an ion exchange device that mixes anion and cation exchange resins in a certain ratio in the same exchange column. The resin layer is evenly mixed, and the Yin and Yang resins are staggered tightly. Each pair of cation resin and anion resin particles is similar to a group of multiple beds, so the mixed bed can be regarded as a series of multiple beds. Since the hydrogen ions and hydroxide ions that enter the water by reverse osmosis after mixed ion exchange can immediately generate water molecules with a lower ionization degree, it is rarely possible to form cations or anion exchange counter ions, so that the exchange reaction is very thorough. Therefore, the water quality of the mixed bed is better than the double bed of yin and yang in series, and the effluent purity is higher
