Gels: liquids in solids

A gel is a jelly-like colloidal system in which a liquid is dispersed in a solid medium.

The process of a gel formation is called gelation. Ex: when a warm sol of gelatin is cooled, it sets to a semisolid mass which is a gel.

Gelation may be thought of as partial coagulation of a sol. The coagulating sol particles first unite to form long thread-like chains. These chains are then interlocked to form a solid framework. The liquid dispersion medium gets trapped in the cavities of this framework. The resulting semisolid porous mass has a gel structure. A sponge soaked in water is an illustration of gel structure.

Gels can be classified into two types: elastic and non-elastic gels.

Elastic gels possess the property of elasticity. When a force is applied, it's shape changes, but when the force is removed, the shape reverts back to the original one. They can be obtained by cooling fairly concentrated lyophilic sols. Ex: gelatin

Non-elastic gels are rigid. Ex: silica gel. They are prepared by appropriate chemical action. Silica gel is produced by adding concentrated HCl acid to sodium silicate solution of the correct concentration. The resulting molecules of silicic acid polymerize to form silica gel.

Properties of Gels:

Hydration: A completely dehydrated elastic gel can be regenerated by addition of water. But once a non-elastic gel loses it's moisture, the addition of water will not bring about gelation.

Swelling: Partially dehydrated elastic gels absorb water when immersed in the solvent. This causes increase in the volume of the gel.

Syneresis: Many inorganic gels on standing undergo shrinkage which is accompanied by excretion of the solvent. This called syneresis.

Thixotropy: Some gels are semisolid when at rest but revert to liquid sol on agitation. This reversible sol-gel transformation is called Thixotropy. Iron oxide and silver oxide gels exhibit this property.

Water purification of activated carbon

Activated carbon can remove chroma, residual chlorine, colloid, organic matter (synthetic detergent, pesticide, herbicide, insecticide, synthetic dye, trihalomethane, halogen acetic acid, endocrine disruptors such as phthalate PAES, etc.), heavy metals (such as mercury, silver, cadmium, chromium, lead, nickel, etc.), radioactive substances, etc.

It is the earliest and most widely used water purification material in the water purifier, not only general activated carbon water purifier, but also in domestic reverse osmosis domestic reverse osmosis pure water machine, as well as in most water purifiers such as ultrafiltration, ceramics, KDF、UV and so on.

The reaction of KDF and chlorine to form zinc ions (Zn2+) may lead to excess zinc in water without such concerns as the removal of chlorine by activated carbon; activated carbon forms a large number of fine pores of various shapes during the activation process, forming a huge surface area with adsorption, with a specific surface area of 500~1200 m2/g, the larger the specific surface area, the better the adsorption effect.

Properties & Structure of B&W Film

The Components of Image Development in B&W Photography

An image or latent image as it is known is the visible image or picture that is produced by exposing photosensitive material such as a photographic film to light.

Photographic film is a strip or sheet of transparent plastic film base coated on one side with a gelatine emulsion containing microscopic light-sensitive silver halide crystals. When exposed to light, a chemical reaction darkens the film to produce an image.

Silver halide emulsions are made by mixing silver nitrate with a solution of alkali halide—typically potassium bromide and iodide—in gelatin. The silver halide then reduces down and forms fine crystals. The light sensitivity of the silver halides is key to the photographic process. It is the sizes and other characteristics of the crystals that determine the sensitivity, grain, contrast and resolution of the film.

The gelatine emulsion will gradually darken by itself if left exposed to light, however this process is too slow to be of any use to a photographer. Photographers instead, instigate in the camera lens a very short exposure to produce a very slight chemical change.

In black-and-white photographic film, there is usually one layer of silver halide crystals. When the exposed silver halide grains are developed, the silver halide crystals are converted to metallic silver, which blocks light and appears as the black part of the film negative. Colour film on the other hand has at least three sensitive layers, incorporating different combinations of sensitizing dyes.

The concentration of dyes or silver halide crystals remaining on the film after development is referred to as optical density. A dark image on the negative is of higher density than a more transparent image.

The Physics!

Most films are affected by the physics of silver grain activation (which sets a minimum amount of light required to expose a single grain) and by the statistics of random grain activation by photons. The film requires a minimum amount of light before it begins to expose, and then responds by progressive darkening over a wide dynamic range of exposure until all of the grains are exposed, and the film achieves its maximum optical density.

Over the active dynamic range of most films, the density of the developed film is proportional to the logarithm of the total amount of light to which the film was exposed, so the transmission coefficient of the developed film is proportional to a power of the reciprocal of the brightness of the original exposure. The plot of the density of the film image against the log of the exposure is known as an H&D curve

Other Layers & Properties of Film

Negatives have additional layers that perform a special purpose. They are as follows:

1. Protective Coating

The overcoating protects the film from friction, scratches, or abrasions (Mainly from human hands) before development. The overcoating is a clear, gelatine layer that is sometimes called the anti-abrasion layer. The protective coating washes away during film processing.

2. Emulsion

As discussed above. This is the thin layer of gelatine that suspends and supports the light-sensitive silver halides. The emulsion is the main part of the film. It is the part of the film that records the image by physically reacting to light that reflects from the scene being photo- graphed, passes through the camera’s lens and strikes the film.

3. Celluloid Base

The base, the thickest of the layers, supports the other layers. Originally, the base was made of glass. However, today the base can be made from any number of materials ranging from paper to aluminium. Photographers primarily use films with either a plastic (polyester) or paper base.

4. Antihalation Backing

The bottom layer of a sheet of film is a very dark-coloured material that prevents halation. This anti-halation backing prevents light from passing through the film and subsequently reflecting back up from any reflective surface under the film. Due to the fact that light reflects at an angle, the reflected light would not return at the same angle as it struck the reflective surface. The dark-coloured material absorbs any light that penetrated the film, thus preventing the light from reflecting and causing halation. The anti-halation backing is washed away during film processing.

5. Noncurl Coating

The non-curl coating is hardened gelatine, about the same thickness as the emulsion, and is applied to the back of the film. A film emulsion swells when wet and shrinks when dry. This contraction produces a strain on a film base because it is highly flexible. The non-curl coating prevents the film from curling during the drying process.

Photographic Paper

Photographic paper works in a similar way to film. When light hits film it causes a chemical reaction that causes special silver-halide crystals to turn black when processed with developing chemicals. All photographic papers consist of a light-sensitiveemulsion of silver halide salts suspended in a colloidal material – usually gelatin - coated onto a paper,

Paper can be catagorised in a number of different ways

1. Contrast and Tonal Flexibility

Graded Papers - are usually high quality and a bit expensive. Graded papers come in grades zero – five. Zero produces the least amount contrast. Five produces the most contrast.

Variable Contrast Paper - when using a black & white enlarger it will havea set of magenta filters. These will be graded similarly to graded papers. The denser the magenta filter, the more contrast your print will have

2. Material

There are two general types of paper:

Fibre-based Paper - is known to produce really good tones and be very stable after processing. Due to the porous nature of the material, it takes a longer time for chemicals to saturate the paper fully. It is also very fragile when wet, so it has to air dry as opposed to being dried in a machine.

Resin-coated Paper - is quick to process, but slightly less stable after development. The chemicals only affect the outer layer of the paper, the developing and fixing process is quicker. It’s also much sturdier.

3. Paper Finishes

This is about the only area that darkroom papers overlap with their modern inkjet paper equivalents. A paper’s finish is the texture and reflectivity of the outer most layer of material. There are several types of finishes that serve a variety of purposes.

A Glossy finish has a high reflectivity and smooth texture. It gives the impression of richer contrast and emphasizes the details and sharpness of an image

Matte paper has a rougher texture and low reflectivity. It tends to mask imperfections and provide a softer look.

There are a number of finishes that fall in between glossy and matte: not totally shiny, but not totally rough. Depending on the brand and the type of paper, these finishes may be called semi-matte, lustre, pearl or satin.

Colloidal Silver is Not Useless

by Yohanan Burket

On an “official” medical site; ie, part of the Rockefeller controlled syndicate, I get the impression that colloidal silver is useless for anything. In their own words:

“Colloidal silver isn't considered safe or effective for any of the health claims manufacturers make. Silver has no known purpose in the body.” See link.

Apparently, this “expert” is unaware, or makes you want to be unaware that colloidal silver was the antiseptic of choice before penicillin. Also, this “expert” is woefully ignorant, as there are silver bandages and silver creams currently on the market, and until recently, colloidal silver was applied to burn patients. Ignorance is not bliss. He probably doesn't mention the silver bandages or silver creams, as they are put out by his pharmaceutical buddies. His true mission is to destroy any competition for their products.

I will “throw him a bone” on his comment about colloidal silver being ineffective against fungus and viruses, but he is dead wrong about silver's impact on bacteria, 650 strains to be more precise. Yes, there are some unscrupulous characters that falsely claim that silver kills cancer, etc. The same author states:

“Manufacturers of colloidal silver products often claim that they are cure-alls, boosting your immune system, fighting bacteria and viruses, and treating cancer, HIV/AIDS, shingles, herpes, eye ailments and prostatitis..” Same link.

The author mixes truth with lies, as colloidal silver was the premier solution for fighting bacteria up to the 1940s, and I strongly suspect he is aware of it but is trying to deceive you. Note carefully that he is a mainstream propagandist, as he is published on the Mayo Clinic website!

As with anything, too much is not a good thing. If you take a quart of 500ppm colloidal silver daily, it might turn your skin blue. However, if you spray a little 10ppm colloidal silver on your hands to disinfect them, no color change whatsoever will occur, ever. Colloidal silver is great for getting rid of eye infections, too, as long as it is not a silver compound, but rather silver particles (ionic silver). I've discovered that colloidal silver ingested internally is also great for getting rid of urinary tract infections. The best part of using colloidal silver for attacking bacteria is that you can make it yourself, and there are machines on the market for this purpose.

If you would like to try colloidal silver first before purchasing a colloidal silver generator, I offer it on my site, www.outoftheboxremedies.com. I personally find the colloidal silver handy when I go out for dinner, as I can immediately disinfect my hands before touching food, such as bread.

More powerful substances are needed to get rid of coughs caused by excess phlegm in the nose and throat, and they are also offered on my website. These more powerful substances, namely iodine and 3% food grade hydrogen peroxide, ARE capable of dealing with fungus and viruses.

Silver solution is not selling.

Enjoying reading zoz, waiting are new issues, am enjoying posts by candidate for medical sciences Iljas Vorontsov , he advises using silver water, not are antibiotics, but am searched at internet,asked in pharmacies and not found silver water, please where I can buy solution?

A long time ago silver water used as decontaminating remedy in infection diseases are fungus, virus, microbe and infections are stable to ion of silver answers Dr. Vorontsov.

But when antibiotics are displayed, thus interest to silver ion s solutions are faded away. And infectionists begun prescribed antibiotics, but later found, that microorganisms are ability having adapting to these preparations and staying to theirs sensitive. And after are new manufactured antibiotics begun. And now are competitions having for infection or antibiotics, but lost. Specialists are share,that we are soon lead to non-comfortable situation, when antibiotics against infections are will not effectivity. But from medicine history are facts shared, that water ,kept in silver pots preventing contagions with bowel infections, and epiphany water keeping for the long time, thanks in pot added silver cross , and plates of silver are high trials. But ion of silver in such water is less, but her presence is preserving, and she is not spoiling. And on practise shows ,that patient with gastritis with pylori infection getting riding of as after drinking everyday silver water on 200 ml. within 6 months, that small dosages are giving decontaminating effect.

And by experience generalization showing,that of using silver are showing ,that ion solutions effectivity in a cure are 30 infection diseases, and apply to these solutions is as remedies, and use by indications, as to drink, wash nose, drink, and in virus infections gargle throat, in angina, use in other cure goals. And for the getting silver water are using special apparatus as silverwares for water. And principle for effect is simple electrode of chemical clean water put in water, and device connect to the electro-net. And of current effect is electrolysing happening, diluting for silver electrode , and water saturating for silvers ions .Such devises you can buy at pharmacy, markets , or internet, and cook at home silver water.

And silver water ready is not selling at pharmacy!

Pulmonary Toxicity Of Silver Vapours, Nanoparticles And Fine Dusts:

This passive photosensitivity response results in silver tattooing of the light-exposed skin. It is believed that silver compounds form complexes with proteins in the pores and skin which cut back to elemental silver when uncovered to light, just like the method colloidal silver for respiratory disease of photograph imaging. Chelating agents haven't any role in removing the silver, though laser therapy appears to be an emerging treatment option with restricted enchancment.

Groh KJ, Dalkvist T, Piccapietra F, Behra R, Suter MJ, Schirmer K. Critical influence of chloride ions on silver ion-mediated acute toxicity of silver nanoparticles to zebrafish embryos. Some sources advocate taking colloidal silver day by day as a preventative, immune booster, or general health tonic. However, in my residence and medical apply, I choose to make use of silver for brief periods to deal with wounds and infections. It’s not totally clear how or why colloidal silver reportedly works so nicely for such a broad variety of health points. One school of thought is that the tiny silver ions present within the colloidal silver resolution are capable of easily penetrate particular person molecules and destroy pathogens of every kind corresponding to parasites, viruses, fungi, and bacteria. However it works, it actually works quickly—proponents of colloidal silver report that it offers fast results.

Similarly, a 2017 examine confirmed that certain intravenous tubing, when lined with silver, resulted in much less bacterial infections in patients who had been within the intensive care unit. Another study from the same research confirmed that yeast infections have been additionally decreased in those with silver-lined intravenous catheters. That being mentioned, colloidal silver for canine is a bacteria-killing machine!

I really feel assured enough to administer these modalities to my household, together with my child and have never had any points but at all times check with your medical physician. My daughter has a weak point in her lungs, mine is often my sinuses. Everytime she will get a virus it always represents with coughing and mucus. One time she had a cough that would not budge it doesn't matter what we tried. Nebulized NAC broke it up within 24 hours and we may all sleep once more. This remains to be a hotly debated subject and more research is required, however some analysis means that it is silver Ag+ ions which have a disruptive effect on the mobile membrane leading to death of the organism.

As a final resort, he may want a lung transplant in the future. While it’s nothing that anyone hopes for, Packard Children’s is well equipped as the only pediatric lung transplant center on the West Coast. Like vancomycin, the other 4 antibiotics are able to causing direct degranulation of mast cells and basophils. Red man syndrome is amplified if these antibiotics are mixed with vancomycin or with each other. It is believed that silver nano-molecules enter micro organism and attach to sure micro organism proteins, causing them to alter structure and become non-functional.

The current research employed the ALICE system to nebulize a defined water-based answer onto cells. Previously, utilizing the ALICE system Lenz et al. in contrast submerged and air-liquid interface exposures for zinc oxide NPs . The authors discovered with dose-response measurements significant differences in mRNA expression of pro-inflammatory (IL-8) and oxidative stress (HMOX-1) markers. Furthermore, Raemy et al. compared aerosol and suspension exposures and found that each exposure strategies differ essentially of their dose-response pattern . Both research emphasize that interactions of NPs with cells depend upon the publicity method. Therefore, a direct comparison of the associated effects of either NPs or ions negates the issue that ions could be launched from the NPs when in suspension, similar to in submerged cultures.

Be positive to observe relevant instructions on product labels and seek the assistance of your pharmacist or physician or different healthcare professional before utilizing. Some research exhibits that using colloidal silver eye drops in each eyes shortly after start does not assist stop certain eye infections in newborns. Other analysis reveals that applying a colloidal silver solution to the eye surface of individuals undergoing eye surgical procedure does not stop infections in addition to making use of povidone-iodine solution.

He was accepted for remedy and reported a first improvement on the third day and complete recovery 5 days later. Antipyretics and nonsteroidal anti-inflammatory medicine had been used as every scientific case required. Concomitant drugs for comorbidities were additionally continued as managed by their usual healthcare providers colloidal silver for respiratory disease. Additional medicines utilized by patients included antiretrovirals, antibiotics, and in two instances hydroxychloroquine. A additional example is Khan et al.’s clinical trial of gargling agents in lowering intraoral viral load among COVID-19 sufferers based in Pakistan .

Our information indicate that publicity to AgNPs could result in induction of the asthma diathesis. Levels of Keratinocyte Chemoattractant , IL-13, CCL11 and IgE in broncho-alveolar lavage fluid at 1, 7 and 21 days after intratracheal instillation of nanosilver particles in Brown-Norway and Sprague-Dawley rats. We suggest that inhalation delivery of the proposed antiviral formulations could be utilized as a first-line intervention while respiratory infections are primarily localized to the upper respiratory system and bronchial tree. Very little evidence helps claims in regards to the well being advantages of colloidal silver.

Two different vital studies have proven nano silver to be highly effective in treating municipal ingesting water. The latter research made use of nano silver coated filtration systems and located colloidal silver for respiratory disease that, at a flow fee of 3l/h, the output depend of E. Coli was zero after 7h filtration, when the input water had a bacterial load of 103 colony-forming models per millilitre (Heidarpour et al., 2011).

Quiz Review #1: Water Quality

hhhhhhh i really don’t want to study tonight but this is a fairly interesting topic so I figured I’d try to bribe myself into some review by posting about it here. alright leggo. giant wall of text under the cut, strap in lads.

Water Quality as it relates to histology is probably an overlooked topic in many labs. Many labs use tap water as a bluing reagent, and so the logic may be that if it’s good enough in that context then it must be fine for other steps in process, such as for water baths and rinsing steps in the H&E strainers. This isn’t the case; the ideal lab will have a water purification system that allows for water that goes through several layers of deionization, filtration and sterilization before it ever comes out of the spigot. But that’s getting ahead of things; let’s talk about why tap water isn’t usually a good idea for use in the histological setting:

Why is tap water bad? Five main Reasons:

Tap water contains inorganic ions, which can negatively effect the quality of a whole bunch of special stains. Silver stains in particular are very vulnerable to inorganic ion contamination; it is common practice at my school to make students do a Gomori Methenamine Silver stain with tap water and a second with DI, just to demonstrate the difference the contrast and background staining issues.

Tap water contains organic contaminants, such as those created by the breakdown of plants and algae. Bacteria and fungi find these substances extremely snack-able, which can lead to some false positives on bug stains. We actually had an issue with this in the lab at my previous rotation; the milipore guys wouldn’t tell us exactly what happened but going by the weird fish smell and the MANY false positive bug stains from that week, we think it was an algal bloom/dieoff that fueled a giant bacteria party in the DI system! Fun times! Another source of organic contaminants is the breakdown of plastic shipping materials and plumbing pipes, such as the polymers that leach out of PVC and water carboys. These are usually indicated by a harsh ‘chemical-y’ smell.

Certain areas of the country may have issues with particulate and colloid pollution; most of the large particles (sand, rocks, plant bits) should be filtered from tap water by waste management, but certain substances such as calcium carbonate (aka limescale) are hard to get rid of and may cause crusty deposits on machinery and artifacts on slides.

Tap water can contain bacteria and their by-products, which is a big issue if you’re running any number of bug stains or histochemical enzyme tests. The bacteria themselves can give you a false positive on things like Grams, Gomori and Warthin-Starrys, and those bacteria contain can also cause degrade endogenous nucleic acids and screw up F/ISH testing.

The last and probably rarest class of tap water pollutants is Gases and Fumes,including things like carbon dioxide, nitrogen, and fumes from acids and volatile solvents used in the lab. Carbon dioxide in particular can be an issue, because too much CO2 in water will cause it to acidify, which could mess with everything from basic H&E staining to tissue morphology. Xylene and alcohol evaporate very quickly; a lab with many open containers and/or poor ventilation may have areas where fumes ‘collect’ and these can sometimes condense onto an open water bath (tho can i just say? If your lab has open processors/open vats of xylene just sitting around??? get out of there, you’re going to get sick. rat out your management to OSHA. love yourself. jeeze).

Alright so now you know why tap water is garbage, now let’s talk about how to measure the degree and severity of how garbage it might be.

Measuring contamination:

Resistivity: a measurement of how strongly the water opposes an electical current moving through it. Remember genchem? yeah it sucked, but remember when you did that experiment where you put different salts into water and then recorded how easy or hard it was for an electric current to get through said water? It’s like that, but the inverse; resistivity is the inverse of conductivity. Pure distilled water does not conduct electricity well; it has a high resistivity. If your water has a bunch of inorganic contaminants in it, it will have a low resistivity, it’s going to conduct electricity very well, and the College of American Pathologists will yell at you and make you fix it or your lab will lose accreditation. Resistivity is measured using certified and calibrated meter. Details about the calibration of the meter and the periodic resistivity testing you do on your lab’s DI system should be recorded and presented to CAP when they come a-knockin’ at inspection time.

Colony Forming Units: this is a measure of bacterial contamination where you plate some of your DI water onto some agar and see what grows. Make the nerds down in Micro do it so you don’t contaminate the plate with the sleeve of your scrubs and give yourself a heart attack. This is another measurement of water quality that CAP’s going to want to see during inspection, so keep good records.

Alright so now we know what garbage is in tap water, we know how to measure that there garbage, now let’s figure out how to make some water that isn’t terrible, some nice pure delicious Science Water ® :

Purifying water: Seven ways

Distillation: Mankind’s been doing this one for thousands of years, tho usually it’s for getting drunk. The idea is to boil water and collect the steam that comes off. This will get rid of larger particulate pollution but may not get rid of some chemical pollution, so it’s best paired with another method.

Reverse osmosis: ‘RO’ involves forcing contaminated water through a very fine membrane under enormous pressure. RO systems are expensive and making large quantities of water using RO can be time consuming, but the water quality they produce is generally worth it.

Ion exchange: ion exchange involves two beds of resin, one positively charged and the other negatively charged. Contaminated water cycles through these beds, and any ionic contaminants are extracted from the water. The water itself dissociates into H+ and OH- ions, which can then be re-constituted to make pure water.

electrodionization (EDI): EDI is a combination of Ion exchange and electrodialysis. The physics of how it works is a little complicated but there’s a nice video about it by Siemen’s here if you’re interested. The important thing to remember is that it is constantly regenerating the resins it uses in the ion exchange step, which makes it attractive to labs who don’t want to do a lot of maintenance (it is still recommended that you replace the ion beads periodically for quality control reasons; everything has a shelf life, you don’t want to push it).

activated carbon: another classic. Carbon tends to be very porous, so if you let gravity pull water down through a thick layer of it, most larger particulates will get caught in these pores. This is neither a specific nor very powerful form of filtration, however, and is best paired with other methods.

UV sanitation: A UV light is used to kill any aquatic life forms that may be in the water. Fishkeepers may be familiar with this method, it’s good for cutting down on algal blooms.

Fine Filtration: a variety of filters can be used to reduce the amount of particulate pollution in water. they are split into two main categories: microporous and ultrafiltration. Microporous filters are basically large mats of fibrous material that physically trap particles while letting water flow through. Ultrafiltration membranes work at the molecular level, separating molecules based on size. Filtration with the method is extremely slow, so most labs opt to only use ultrafiltration for cell culture and molecular techniques.

So there’s an important question outside of all the different filtration choices, and that is: How pure do you *need* your water do be? How much of it do you anticipate your lab needing? How fast do you need it to be able to replenish? Most labs will decide to choose some combination of these methods in order to best meet their needs and deal with the contaminants presented by their local water sources. The lab for my current rotation uses a combination of RO, EDI and UV, and circulates/re-filters unused DI several times each hour to avoid stagnation. We also have a number of rules about decontaminating pitchers, carboys and water lines within our stainers. We are strongly encouraged to use clear glass containers whenever possible even tho we all wear gloves all the time so we drop beakers all over the place ive only been there two weeks and its almost happened to me twice now

There are several classifications of water set by the Clinical Laboratory Standards Institute with varying degrees of purity for use in the laboratory setting:

Clinical laboratory reagent water (CLRW): In my lab, this is what comes out of the DI tap. It’s whats called for in most stain recipes and is what we put in flotation baths.

Special reagent water: we use this for reconstituting antibodies and the F/ISH team uses it for PCR. It comes from the milipore machine in the genetics ward because they need it more often and apparently the machines are very expensive so we only get one per department.

instrument water: It won’t clog your stainer lines but it’s not good enough for your flotation bath.

‘water supplied by instrument manufacturer’: I’m told no one does this any more. apparently once upon a time lab machine companies would send you big ol boxes of water in the mail to use exclusively on their machines, but then no one was checking to see how chemically stable the packaging was and there were issues with polymer contamination; this was very much before my time so i don’t have a lot of details.

Commercially bottled purified water: another method that’s no longer popular since apparently most bottled water is just tap water from someplace else and you’d still have to plate for CFU’s, test for resistivity etc

autoclave and wash water: tap water. Remember though, you should always give your glassware a final rinse with DI before hanging it up to dry toget rid of anything funky in the tap water.

So yeah that’s how you make and monitor some sweet sweet Science Water, aka the Good Stuff. My next unit is on PAS/PASD, that’ll probably be up next sunday-ish. Til then,

-Reby

Water treatment equipment

1. RO reverse osmosis membrane method water treatment skills

RO reverse osmosis is a kind of pure water machine (also known as terminal water equipment) that can be directly consumed by humans by filtering raw water (physical method) without adding any compounds through the current popular international reverse osmosis method. ). The municipal tap water whose water quality complies with the regulations of the Ministry of Health's "Sanitary Standards for Daily Drinking Water Quality" (2001) is used as the raw water, and the raw water is pre-treated through two activated carbon filter elements (1 granular activated carbon, 1 sintered activated carbon) and 1 PPF soluble spray filter element. Filter, and then apply pressure to the pre-filtered water to make it pass through a RO (Reverse Osmosis) membrane with a pore size of 10,000 microns, and finally pass through the silver-loaded activated carbon (also called small T33) Adjust the acidity and alkalinity of the water (make the pure water taste sweet and mellow) and produce pure water.

2. Microfiltration and transfiltration water treatment skills

Microfiltration method is a microporous filter membrane made of cellulose or polymer materials, using its uniform pore size to trap particles, bacteria, colloids, etc. in water so that it is not removed through the filter membrane. This microporous membrane filtration technology, also known as particle dense filtration technology, can filter micron or nanometer particles and bacteria. Both transfiltration and microfiltration are attributed to membrane separation skills. There is no significant boundary between the two. The operating pressure of transfiltration is generally about 0.3 MPa, which can remove macromolecular substances, bacteria, viruses, etc. in water, but the flux is relatively high.

III. Compound water treatment skills

When the water treatment equipment of one process is difficult to remove harmful substances in the water, two or more processes are selected as the composite type. Such as activated carbon adsorption? ultraviolet sterilization, activated carbon adsorption? reverse impregnation, activated carbon adsorption? microfiltration (beyond filtration), polypropylene ultrafine fibers, microfiltration (beyond filtration) and so on.

4. Softening water treatment skills

There are two kinds of soft water skills commonly used in water treatment equipment of soft water machines. One is to remove calcium and magnesium ions in the water through ion communication resin, and the hardness of the water is reduced. The other is the nanocrystalline technology, namely TemplateAsistedCrystallization (module assisted crystallization), which uses The high energy of the nanocrystals packs the free calcium, magnesium and bicarbonate ions into nanometer crystals, and then blocks the free ions to form scales.

V. Distillation water treatment skills

Distillation refers to boiling water and then collecting steam to cool and condense it into a liquid. Distilled water is extremely safe drinking water, but there are some issues to discuss further. Because distilled water does not contain minerals, this has become the reason for opponents to propose that human life is simply aging. Other methods using distillation have higher cost and consume power, and cannot remove volatile substances in water.

Six, boiling water treatment skills

Boiling method refers to drinking after tap water is boiled. This is an old method and is widely used in the country. Boiling water can kill bacteria, but some chemicals and heavy metals can not be removed, even if its content is extremely low, so it is still unsafe to drink.

VII. Magnetization water treatment skills

Magnetization method refers to the treatment of water using magnetic field effect, which is called magnetization of water. The process of magnetization is the process of completing magnetization after water passes through the magnet in the direction perpendicular to the lines of magnetic force. The magnetization treatment of water in my country is still in the preliminary stage of practice and research until now. The Hyde Energy water purifier abroad does not require the magnetization function, because the magnetized water is not attributed to the planning of clean water, but to medical problems.

Eight, mineralized water treatment skills

Mineralization method refers to adding mineral elements (such as calcium, zinc, strontium and other elements) beneficial to human body to the water on the basis of purification. Commercial water purifiers generally reach the intent of mineralization by adding maifan stone to the water purifiers, but the Ministry of Health of the People's Republic of China has now clearly stated that "water-related products must not promote any health function." Ozone and ultraviolet sterilization can only be sterilized. The heavy metals and chemicals in the water cannot be removed. The dead bodies of the killed bacteria remain in the water and become a pyrogen.

9. Electrolytic water treatment skills

Electrolysis is the electrolysis of purified water, which started in Japan. This kind of equipment is called electrolyzed water machine. It is to purify the water first, and then to carry out electrolytic activation. Its alkaline activated water corresponds to the PH value of the human body environment. It has a health care effect on the human body and is suitable for drinking; acidic activated water can be used for face washing, bathing, and beauty effect. However, the strength of the electrolyzed water to the human body needs further discussion.
