Cost Effective 254nm UV Water Sterilizer For Drinking Water Treatment
Drinking water
In order to destruct pathogenic microorganisms which exist even after several steps of treatment
processes, UV treatment has been suggested as the solution instead of conventional treatments that
have their own limits such as insufficient treatment, cost burden, environmental pollution, deterioration of water quality or odor. UV does not cause odor or DBPs (disinfection by-products) and effectively inactivates several pathogens like Cryptosporidium, Giardia which are highly
tolerant to chlorination. UV is used worldwide in millions of drinking water treatment plant as it guarantees stable performance, can minimize chlorine input, is easy to operate, and is not affected by water
temperature or pH value.
Working principle:
Our Ultraviolet Water Treatment Systems disinfect your water without changing its chemical composition and physical structure by eliminating 99.99% of all bacteria and virus content with the use of ultraviolet light. A.O. Smith Ultraviolet Water Treatment Systems are used in a wide array of different applications from low and high capacity potable water treatment, the treatment of residual water from industrial processes and also the treatment of waste water. Thanks to high density amalgam lamps, you can obtain high efficiency with low power consumption.
Ultraviolet devices possess a high quality, stainless steel reactor housing. All welding is conducted using the plasma arc-fusion method and the reactor housing is passivized through electropolishing. High quality UV lamps and high permeability quartz sleeves yield the highest sterilization performance along with various other long-term operational benefits. The high flow rate and modular design of the ultraviolet devices that have been designed by A.O. Smith Water Technologies utilizing long years of experience and high engineering technology offer you water disinfection capabilities in all capacities
Product features:
UV light will kill any DNA based micro organism when give enough UV dosage.
UV break micro organism’s DNA in a cumulative basis.
Continuous disinfection in cooling water. If micro organism is not effectively deactivated on the first disinfection cycle and in the next cycle it get UV treated.
For 90% kill algae 30000 μWs/cm2 is required for one cycle .
UV spectrum between 185-400nm has a strong germicidal effect, with peak effectiveness at 265nm.
UV works instantaneously against all water-borne microorganisms, including bacteria, viruses, molds, spores and protozoa – including those resistant to chlorine.
UV systems are also very easy to use and can be effectively monitored and integrated with online process control systems.
UV disinfection systems are very compact, modular and easy to
install into existing water treatment systems.
UV does not cause the formation of chemical disinfection by-
products, many of which can have undesired effects of their own.
UV sterilizer is eco-friendly and cost effective.

Application
Ultraviolet water purification systems are used in many applications that includes home/residential (both
well water and municipal water supplies), commercial, and industrial. Here is a list of several applications
where the power of UV water sterilizers are commonly used to treat and protect the water supply for
contaminates such as bacteria and viruses. UV systems applications include private wells, campgrounds, hotels, bottlers, aquaculture, hospitals, food, cottages, restaurants, breweries, water systems, laboratories, marine, pharmaceutical, dairies and many other applications.
FAQ:
Q. How do ultraviolet ("UV") sterilizers work?
A. UV sterilizers work by exposing water to powerful germicidal ultraviolet light. DNA and protein links in bacteria are destroyed by exposure to this light.
Q. Does the water become radioactive by this radiation?
A. No. No radiation residual or any chemical residual is left in the water as a result of the UV rays.
Q. Do these systems come in different sizes?
A. Yes. The size of the systems is directly proportional to the flow rate of the water in gallons per minute. The higher the flow rate, the larger the system and lamp.
Q. Does the water have to sit in the UV sterilizer to be disinfected?
A. No. If the system is sized correctly, the water is disinfected as it flows through.
Q. What if the water flows faster than is allowed through the system?
A. If the flow rate exceeds the design flow rate of the UV sterilizer, then there is a possibility that the water will not be properly disinfected. It is important to use a flow restrictor so that the flow rate cannot be exceeded.
