How Hot Tub & Spa UV Works

A Powerful Does of Ultraviolet Light Does the Dirty Work

SpectraLight turns hot tub nightmares into hot tub maintenance freedom. And UV does it better than anything else on the market. SpectraLight UV harnesses the power of ultraviolet light to eliminate microorganisms, lower chemical usage, and eliminate toxic by-products. SpectraLight harnesses the power of UV light to make your spa or hot tub safer, healthier, and easier to manage than traditional sanitation methods.

What is UV Spa Disinfection?

UV spa disinfection is a cutting-edge, non-chemical process that uses germicidal UV light rays to sanitize hot tub water. Ultraviolet spa disinfection units emit a high intensity germicidal light ray that alters or disrupts the DNA or RNA of targeted organisms such as algae, bacteria, and protozoa. The highly concentrated electromagnetic energy also destroys organic matter found in hot tubs and spas, eliminating the formation of dangerous chlorine by-products. The by-products have been linked to asthma, allergies, and even cancer.

SpectraLight bombards passing water flow with a high intensity UV-C germicidal light rays.

Where Did Ultraviolet Spa Sanitation Get its Start?

The UV light spectrum was discovered with the identification of light waves. Scientists have known for almost a century that UV is a powerful neutralizer of algae, bacteria and viruses. Ultraviolet hot tub sanitation is relatively new, however; UV disinfection has been around for more than 30 years. Ultraviolet disinfection was first used to sterilize drinking water, and has since gained in popularity in drinking water and wastewater disinfection in the last 10 years. Now ultraviolet systems disinfect a significant percentage of all drinking and wastewater. The big news is that New York City has designed the world's largest drinking water facility, capable of treating two billion gallons per day. New York will install twelve thousand ultraviolet lamps - the same type of lamps found in SpectraLight UV sanitizers.

How Ultraviolet Hot Tub and Spa Technology Works

SpectraLight UV for spas and hot tubs is installed in the piping used in your spa's circulation system. SpectraLight works with all makes and models of spas and hot tubs. SpectraLight UV bombards passing spa water flow with a high intensity germicidal ultraviolet ray that destroys more than 60 waterborne pathogens, including algae, bacteria, and viruses. The UV lamp is housed in an industrial graphite housing optimized for high flow rates. A highly specialized quartz glass sleeve protects the lamp from passing water while transmitting 99.9% of the UV light. The highly concentrated electromagnetic energy destroys organic matter that causes major problems in warm water spas and hot tubs. Ultraviolet light eliminates pathogens within seconds of passing through the UV sterilization chamber.

Is Ultraviolet Hot Tub and Spa Disinfection Safe?

Ultraviolet hot tub and spa disinfection is very safe. The ultraviolet lamps are housed in a rugged, high-impact polymer housing. Ultraviolet cannot leave the sterilization chamber, so UV never enters the spa or hot tub. Ultraviolet disinfection is a physical process rather than chemical, making UV the most environmentally friendly choice in hot tub sanitation. There is no residual effect that is harmful to humans, animals, aquatic life, plant life or the environment. Ultraviolet also minimizes the need to generate, handle, transport, or store dangerous chemicals.

Is Ultraviolet Spa Disinfection Effective?

Ultraviolet is considered the best available technology for spa and hot tub disinfection. Studies show that in chemical disinfection, 90% of the chemicals are used for oxidation, and 10% for sanitation. Ultraviolet does both. Hundreds of commercial aquatic centers across the nation have installed UV. These systems often cost between $50,000 and $100,000 dollars. But UV systems for spas and hot tubs are much smaller in size and scale. And now, SpectraLight has made spa and hot tub UV systems more affordable for everyone.

What Do the Authorities on Water Purification Say About UV?

According to the United States Environmental Protection Agency, "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." This has prompted some states to require ultraviolet disinfection systems.
