Operation of the UV water pool treatment system

During the filtration cycle, the water circulates inside the BIO-UV reactor. Bacteria, viruses and algae, subjected to UV-C radiation are inactivated without the addition of harmful by-products or chlorine.

To perfect the disinfection, the injection of BIO-UV Remanent Oxygen (exclusive product) makes the water completely disinfectant.
