UV radiation from ultraviolet water systems' bulbs and lamps is not suitable as the sole method of filtration for water with high levels of suspended solids, turbidity, color, or soluble organic matter. These materials can react with the UV radiation and reduce disinfection performance. Water turbidity makes it difficult for the ultraviolet radiation to penetrate water. If your water supply has these characteristics, a sediment prefilter
(of 5 microns or less) should be installed before the UV water purification system to remove particulate matter prior to UV water disinfection.
Safety and Efficiency Notice: UV lamps operate at 600 to 850˚c. Avoid allowing bare skin to come in contact with the Trojan quartz sleeve, as oils and residual compounds from the skin left on the sleeve will cause permanent etching (devitrification) when heated. This will reduce UV energy transmission. A contaminated lamp will eventually overheat, causing premature failure. Alcohol wipes and rubber gloves are included with every purchase of a quartz sleeve or lamp. In case of contact with bare skin, decontaminate lamp with alcohol wipe before returning it to use.
