When bacteria, viruses, and other microorganisms are exposed to Ultraviolet light at a particular wavelength (253.7 nanometers) their reproductive capabilities are destroyed, which means that they are inactivated and no longer pose a threat to human health. Water enters the unit through the inlet port of the Ultraviolet generator cell. The water flows through the generator cell and swirls around a low pressure mercury vapor lamp, which emits powerful Ultraviolet light energy. Vital genetic components contained in microorganisms absorb the light, and ultimately destroying the organism.

Ultraviolet radiation is a type of light, unlike visible light, that cannot be seen. Its wavelengths, expressed in Angstrom units (one Angstrom unit wavelength equals one hundred-millionth of a centimeter), are shorter than the wavelengths of visible light and carry more energy. Because of this high concentration of energy, UV radiation has the unique ability to kill microorganisms with which it comes in contact.

U.V. disinfection is environmentally and user friendly, with no dangerous chemicals to handle, store, or risk overdosing. With only two water connections and a power cord, installation is made easy. The SE-7 system is an economical unit, with a built-in lamp out alarm circuit.

This optional true U.V. Monitor reads only the 254-nm intensity output of the ultraviolet light within the U.V. treatment chamber. This U.V. monitor unit has built in alarms to warn of inefficient performance or lamp failure.

UV sterilization of drinking water is environmentally safe and user friendly, with no dangerous chemicals to handle, store, or risk overdosing. The DWS-48 system is an economical unit designed for commercial use.

UV sterilization of drinking water is environmentally safe and user friendly, with no dangerous chemicals to handle, store, or risk overdosing. The DWS-80 UV sterilizer is an economical unit designed for commercial use.
