UV water disinfection systems are trusted to provide clean, healthy water, but they can't do their job if they aren't maintained properly. You need to change the germicidal UV lamp once a year, and make sure that all of the other parts are working correctly. US Water Systems offers a number of disinfection system parts, including UV sleeves, lamps, and ballasts, for the most popular ultraviolet water disinfection systems. We carry parts for Hydro-Safe, Polaris, Sterilight, Trojan, and other brands – and, of course, you'll get great deals on parts for US Water UV systems too! Not only do we have reliable products at reasonable prices, we also offer experienced tech support from Certified Water Specialists. Call 1-800-608-8792 and we'll be glad to discuss your water problems or system issues.
UV radiation can be used for multiple purposes in water treatment, but it is primarily employed as a tool to disinfect water, inactivating pathogens without chemicals. For other applications, UV can be used for the removal of organic and inorganic chemicals, including chlorine, chloramines, ozone and total organic carbon (TOC). When combined with oxidants such as ozone or hydrogen peroxide, or semiconductors such as titanium dioxide, UV can be used for the oxidation of refractory chemicals such as chlorinated solvents, taste and odor compounds, and other emerging contaminants.
UV System Parts
A UV water disinfection system is made up of several important parts:
Germicidal UV lamp
Ballast or controller unit
Each of these parts must be in good working order to allow the system to work as it should. Water flows into the reaction chamber, which is sealed using O-rings. Inside this chamber is the UV lamp, which sits inside a quartz UV sleeve. The sleeve is a long, clear tube that protects the lamp while still allowing the correct UV rays to pass through and do their job. The ballast or controller powers the unit and controls the output of the germicidal UV lamp.
The UV lamp should be changed once a year to ensure that it's operating at peak efficiency. Always replace an old lamp with a new one designed to fit your system and provide the required dose of UV radiation to disinfect your water. When you replace the lamp, check the quartz sleeve; UV sleeves can become fouled with various contaminants over time. You may need to clean the sleeve or replace it if it's damaged or cannot be completely cleaned. It's a good idea to check your UV ballast at the same time to make sure that it's providing the power and control that you need.
