PACT - Model UV -Wastewaster Ultraviolet Disinfection

Ultraviolet disinfects waste water by damaging the DNA and RNA of microorganisms such as salmonella, giardia, microscopic worms and viruses. PACT UV systems can have lowpressure or medium-pressure lamps. Medium-pressure lamps are normally used at large treatment facilities. The effective UV dose is dependent primarily on the combined effects of the UV light intensity, the exposure time and the UVT (ultraviolet transmittance). UV Transmission varies over time and from site to site as it is related to the quantity of organics, colloidal solids and other material in the water, which absorb and scatter the UV light as it passes through water.
