The use of UV light to sterilize and disinfect drinking water has a long history of success and is in fact being used in most municipal water treatment plants built in the last 20 years. The invisible rays of UV light are able to produce this very useful effect by mimicking nature. In nature, rays of the sun carry (among others) UV light in the germicidal wavelength of 254 nm. This particular wavelength of light is very damaging to living cells – hence the warnings to reduce human exposure to long periods of high intensity sunlight – and it's lethal on the microscopic level to living pathogens in drinking water. Our UV systems are able to provide safe water in regions where the water supply is suspect or in cases where the water supply is contaminated and otherwise unsafe to consume. The technology is very effective against pathogens including bacterial, viral and protozoa contamination and in many cases can be outfitted to provide safe water even in regions where there is little or no access to electrical service. The use of solar panels to power UV systems has become popular in many parts of the developing world. Proper water treatment can make an enormous difference in the quality of life, and in the quality of commercial and industrial goods and/or processes We Kill Harmful Bacteria and Other Pathogens Including E. coli Cryptosporidium Coliform Giardia Legionella Staphylococcus Cholera Mold Anthrax Poliovirus Streptococcus Hepatitis Tuberculosis Influenza Coxsackie Shigella Typhoid Rotavirus Salmonella Adenovirus Campylobacter Toxoplasma Ultraviolet Sterilization Technology Ultraviolet disinfection systems are mysterious to many people – how can “light” kill bacteria? But the truth is it can. Ultraviolet (UV) technology has been around for more than 60 years, and its effectiveness has been well documented both scientifically and commercially. It is nature’s own disinfection/purification method. With consumers becoming more concerned about chlorine and other chemical contamination of drinking water, more dealers are prescribing the ultraviolet solution suitable for both small flow residential applications as well as large flow commercial projects. Ultraviolet is a means of killing or rendering harmless microorganisms in a dedicated environment. These microorganisms can range from bacteria and viruses to algae and protozoa. UV disinfection is used in air and water purification, sewage treatment, protection of food and beverages, and many other disinfection and sterilization applications. A major advantage of UV treatment is that it is considered safer and more reliable for disinfection of water than chemical alternatives, while the level of disinfection is much higher. UV treatment systems are also extremely cost efficient and require less space than alternative disinfection systems. Advantages of UV Sterilization Following are the advantages of UV sterilization: Environmentally friendly, no dangerous or toxic chemicals to handle, no problem of overdosing (it’s impossible), no need for specialized storage equipment, no WHMIS requirements. Low initial capital cost as well as reduced operating expenses when compared with similar technologies such as ozone, chlorine, etc. Immediate treatment process, no need for holding tanks, long retention times, etc. Extremely economical, hundreds of gallons may be treated for each penny of operating cost. No chemicals are added to the water supply – no chlorinated by-products are generated (i.e. chlorine + organics = trihalomethanes). No change in taste, odor, pH or conductivity or the general chemistry of the water, essential minerals and trace elements remain in the water Automatic operation without special attention or measurement, operator friendly. Simplicity and ease of maintenance, periodic cleaning (if applicable) and annual lamp replacement, no moving parts to wear out. Easy installation, only two water connections and a power connection. Compatible with all other water processes (i.e. RO, filtration, ion exchange, etc.) Factors Affecting UV Because UV does not leave any measurable residual in the water, it is recommended that the UV sterilizer be installed as the final step of treatment and located as close as possible to the final distribution system. Once the quality of your water source has been determined, you will need to look at things that can inhibit the UV from functioning properly (e.g., iron, manganese, TDS, turbidity, and suspended solids). Iron and Manganese will cause staining on the quartz sleeve and prevent the UV light from transmitting into the water at levels as low as 0.3 ppm of iron and 0.05 ppm of manganese. Proper pre-treatment is required to eliminate this staining problem. Total Dissolved Solids (TDS) should not exceed 500 ppm. There are many factors that make up this equation such as the particular make-up of the dissolved solids and how fast they absorb on the sleeve, again impeding the UV energy from penetrating the water. Turbidity is the inability of light to travel through water. Turbidity makes water cloudy and aesthetically unpleasant. In the case of UV, levels over 1 NTU can shield microorganisms from UV light, making the process ineffective. Suspended Solids need to be reduced to a maximum of 5 microns in size. Larger solids have the potential of harboring or encompassing the microorganisms and preventing the necessary UV exposure. Pre-filtration is a must on all UV applications to effectively destroy microorganisms to a 99.9% kill rate. Additional Factors UV levels fluctuate with temperature levels. The optimal operating temperature of a UV lamp must be below or near 40 C (104 F). Typically, a quartz sleeve is installed to buffer direct lamp-water contact, thereby reducing any temperature fluctuations. The UV dose applied to the water decreases significantly with temperatures over 40 C. UV Applications One of the most common uses of ultraviolet sterilization is the disinfection of domestic water supplies due to contaminated wells or surface water sources. Coupled with appropriate pre-treatment equipment, UV provides an economical, efficient and user-friendly means of producing safe potable water.
