Ultraviolet (UV) Water Sterilizer System by Huaheng Industry are specifically designed to remove microorganisms that can range from bacteria and viruses to algae and protozoa. It's advanced UV treatment is capable of disinfecting water faster than chlorine without the use of retention tanks and harmful chemicals to your drinking water. The UV lamp emits powerful ultraviolet light and incorporates natural ultraviolet light energy to eradicate microbiological contamination. Water enters through the bottom part of the reactor chamber and swirls around a high output, low pressure mercury vapor lamp thermally protected by a quartz sleeve. Energy components contained in microorganisms absorb the light energy; this disrupts the DNA and prevents reproduction.
