Today most commercial pools or spas are treated using chlorinated products that are good oxidizing agents but generate by-products such as chloramines.These by-products are irritant, corrosive and smelly. They are harmful to health and responsible for respiratory illnesses in lifeguards, baby swimmers and competitive swimmers. That is why BIO-UV has designed ranges of UV reactors suitable for commercial pools and spas in order to reduce or eradicate these secondary effects.
