UV Pool Sanitizers

Ultraviolet pool sanitizers probably do the best job at sanitizing your pool than any other pool sanitization method. UV pool sanitizers work by harnessing the power of ultraviolet light to eliminate microorganisms, lower chemical usage, and eliminate toxic by-products. Essentially, it just disinfects your pool with a powerful light ray. It ultimately makes your pool safer, all around healthier and much easier to manage. Studies show that in chemical disinfection, 90% of the chemicals are used for oxidation, and 10% for sanitation. Ultraviolet does both.
A UV sanitizer works by means of the pump, which draws water from the pool and is then directed to the filter. The filter then traps particles and debris. After the water is filtered it is directed to your UV Sanitizer. The filtered water enters the inlet of the UV sanitizer. Water flows through the length of the UV chamber. It is inside the chamber that microorganisms absorb powerful UV light. It is this light energy that destroys or inactivates these pathogens. The highly concentrated electromagnetic energy destroys organic matter and eliminates the formation of dangerous chlorine by-products called chloramines that commonly lead to red, stinging eyes, skin irritations, asthma and allergies. The water then leaves the UV chamber it is returned to your pool. Many pools have a chlorine feeder which can be metered so you can control the level of chlorine.
UV sanitizers are very safe. The UV never enters the swimming pool. UV is a physical process rather than a chemical process, making UV the most environmentally friendly choice in pool sanitation. There is also no residual effect that is harmful to humans, animals, aquatic life, plant life or the environment. UV also minimizes the need to generate, handle, transport, or store dangerous chemicals.
According to the United States EPA, “…UV has been found to be an effective disinfectant…simplicity of installation, ease of operation and maintenance, and low cost relative to chemical disinfection make UV a useful technology…” According to the World Health Organization, “Lower free chlorine concentrations may be health protective when UV is used.” Some states are beginning to require UV on public pools. The state of New York recently mandated ultraviolet pool systems use on all public spray parks.
