Did aliens have a hand in building the pyramids? It’s a debate that has raged for decades, but nobody ever asks... Did the doctor help build the pyramids?
Let’s consider the clues left by the ancients...

Our UVC LEDs based modules... an sanitization service without precedent !
Water is the foundation of life; therefore, wetlands present a particular risk of infection, promoting microbial growth and serving as a source of antibiotic-resistant pathogens and healthcare-associated infections.
For example, in health care facilities, the ways we use water are more diverse and patients may be more vulnerable to infections. Some conditions in health care plumbing systems can even promote microbial growth. This can lead to dangerously high levels of potential pathogens. In addition, the risk does not stop with tap water - each use of water in patient care facilities must be examined and assessed for its risk of harbouring and transmitting pathogens associated with care.
Even hospital sink drains and toilets can pose a risk of harbouring antibiotic-resistant pathogens that can spread to patients and cause damage. Our UVC LED modules can provide to your company a real solution for Water treatment, Air-Surface disinfection ! We can design and customize our products to fit your specific needs and you will be able to offer your customer the most efficient UVC LED based systems existing today.

IIT Guwahati develops low-cost UVC LED system to amid COVID-19
Navneet Kumar Gupta
Newswave @New Delhi
Indian Institute of Technology Guwahati has developed a low-cost UVC LED based disinfection system amid the Coronavirus outbreak in the country. The team is also addressing the critical need of the material required for the Personal Protective Equipment (PPE) i.e. fabrication material should have a waterproof ability.
IIT Guwahati
Prof.T.G.Sitharam, Director, IIT Guwahati, has formed a research team lead by Dr. Senthilmurugan Subbiah, Department of Chemical Engineering, IIT Guwahati, to work in collaboration with M/s Excel Tech based in Bangalore and Ultimate Aeroaqua Filter Private Limited based in Guwahati to develop the two technologies.
Dr. Senthilmurugan Subbiah, Department of Chemical Engineering, IIT Guwahati, said, “IIT-,PPEG community is focused to work closely with government agencies and industrial partners to develop smart and low cost technologies to fight against COVID 19 under the leadership of Prof. T. G. Sitharam, Director, IIT Guwahati.”
UVC LED system to disinfect areas
UVC system is a proven technology to sanitize the microorganism infected non-porous surface. 90 % killing rate can be achieved by UVC for one of the highly stable virus MS-2 Coliphase with 186 J dose, whereas 36 J dose is needed for Influenza virus which is similar to COVID-19. In this project, the team has developed a UVC LED system capable of providing 400 J dose in 30 seconds, such that virus-infected surface will be sanitized. The unique design of this UVC system will ensure uniform UVC exposure in virus-infected non-porous area. Further to adopt this technology to porous surfaces, the team is improving the design by integrating UVC with Ozone system such that surface with porous nature also can be sanitized.
Another critical aspect of the technology is the safe usage of UVC system while sanitizing. The system is equipped with an object movement identification feature so that UVC exposure to human skin is avoided during the operation. The primary role of IIT Guwahati is to develop the UVC system design, prototype (using 3D technology), and testing it in its laboratory. Three of them are designed for household sanitization and one of them for sanitizing bigger spaces like hospital wards, buses, metros, and railway compartments, including those transformed for COVID-19 care.
UVC LED system is under design and prototype development. The industrial partner was able to source required raw material to produce 5000 number of floor sanitization UVC system. The industrial partners are in the process of getting special approval from the government agencies to start production during the lockdown period.
Personal Protective Equipment (PPE)
According to the research team, one of the critical requirements that COVID PPE fabrication material should have is a waterproof ability. As a research institute, IIT Guwahati is providing technical support to identify the best waterproof material from the Indian market and its performance concerning waterproof. With identified material, the industrial partner has produced a sample PPE for further waterproof testing. Further, IIT Guwahati team will be exploring potential technology for antimicrobial coating on PPE to reduce the viral load on PPE during exposure to COVID-19.
PPE kit includes a jumped suite, face shield, mouth mask, head covers, gowns and shoe covers. M/s Excel Tech Bangalore and Ultimate Aeroaqua Filter Private Limited foresee a need for at least 1 million PPE kits soon for India and both the companies are working together to meet this demand, with a separate task team assigned for this project. The initial trial for the production of 15,000 PPEs has been completed successfully and 200 PPEs are ready for shipment to IIT Guwahati for further improvement study. Another 2000 PPEs are ready for supply to Northeast hospitals. Both industry partners are working together to ramp up the production by sharing IIT Guwahati’s PPE design with mass production vendors across India. The PPE’s designed in a more sealed manner using the existing manufacturing facilities in India, unlike the current existing PPEs, along with impregnating the materials used with anti-microbial substance. These solutions will not only minimise the spread of COVID-19 but also help in eradicating the traces of the disease at a faster pace. This implementation would also increase the sanitary standards of the country in the long run.

Without protective measures, human eyes and skin are exposed to ultraviolet lights for more than 3 minutes, which may exceed the human body safety boundaries set by the World Health Organization and International Non Ionizing Radiation Protection Committee. If it is directly illuminated for more than 30 seconds, the eye corneum damage causes electro-optical impections, and the eyes suddenly painful, there is a foreign body, cry, tears or eyelids. Long-term irradiation will damage your eyes and skin, causing eye trauma and severe burns of skin, and may lead to skin cancer.
How to use in ordinary homes? The ultraviolet disinfection lamps in the market are classified in two types of ozone and ozone, of which 254 nm is an ozone-free wave-free ultraviolet, 185 nm is an ozone wavelet ultraviolet. There is an ozone-type ultraviolet sterilization lamp, which has strong oxidation, effectively killing bacteria, and ozone diffissuality can make up for the disadvantage of the dead angle due to ultraviolet rays. But the ozone of the excerpt is an invisible killer. It strongly stimulates the human respiratory tract, causing sore throat, chest tightness cough, trigger bronchitis and emphysema, and exhausting need to open the window. Of ozone-free ultraviolet sterilization lights are only spread straight, and they are disinfected, but the ventilation time is short, the risk is small, the family has the old man, children, pregnant women, it is recommended to use no ozone type.
In disinfection time, generally 30 ~ 60 seconds should be suitable to effectively kill viruses and bacteria. Take the murganism of the blue-spectral Trick's hand-held ultraviolet sterilizer, the UVC LED disinfection lamp of Table 10W is irradiated by up to 1 minute; it is forbidden to pick up the eye, the skin does not exceed 30 seconds.
If home, it is recommended to choose a UVCLED's disinfection device, such as mask ultraviolet sterilization, toothbrush UV sterilizer, UV-proof sterilizer, shoe UV sterilizer, etc. Environmentally-friendly non-pollution. Current costs are too high. The mask is recommended to use ultraviolet sterilizers to ensure that the air entering with exhaled is clean and non-polluting.
#UVCLed based systems can prevent any virus spreading, including the #Coronavirus !
The OMS agency recommends strengthening sanitation and hygiene measures to prevent fecal-oral transmission in epidemic area.
These include drinking boiled water, avoiding eating raw food, implementing separate meal systems, frequent hand-washing, disinfecting toilets, and preventing water and food contamination from patients’ stool.
How can we anticipate and prevent infections ? What is the short and long term effective solution ?
