  • Product Description

    Ultraviolet (UV) sanitizing units are used in many water purification systems to control bacteria and have certain applications in animal drinking water systems. UV units can be effective water treatment tools, but it is important to recognize what UV can do, what its limitations are, and what maintenance is required.

    How does UV work?

    Ultraviolet or UV energy is found in the electromagnetic spectrum between visible light and x-rays and can best be described as invisible radiation. In order to kill microorganisms, the UV rays must actually strike the cell. UV energy penetrates the outer cell membrane, passes through the cell body and disrupts its DNA preventing reproduction. UV treatment does not alter water chemically; nothing is being added except energy. The sterilized microorganisms are not removed from the water. UV disinfection does not remove dissolved organics, inorganic or particles in the water.

    The degree of inactivation by ultraviolet radiation is directly related to the UV dose applied to the water. The dosage, a product of UV light intensity and exposure time, is measured in microwatt second per square centimeter (µws/cm2 ). The accompanying table lists dosage requirements to destroy common microorganisms. Most UV units are designed to provide a dosage greater than 30,000 µws/cm2 after one year of continuous operation. Notice that UV does not effectively disinfect some organisms (most molds, protozoa, and cysts of Giardia lamblia and Cryptosporidium) since they require a higher dose.

    UV units for water treatment

    Special low-pressure mercury vapor lamps produce ultraviolet radiation at 254 nm, the optimal wavelength for disinfection and ozone destruction. The UV lamp never contacts the water; it is either housed in a quartz glass sleeve inside the water chamber or mounted external to the water which flows through UV transparent Teflon tubes. Some ultrapure water systems use 185 nm UV units for reducing TOC (total organic carbon).
