Here are some key disinfection applications of chlorine dioxide:- Drinking water treatment - Wastewater/sewage treatment- Industrial process water treatment- Cooling tower water treatment- Air treatment in industrial settings- Control of mussels in water systems- Disinfection of foodstuffs and food processing facilities
This document discusses the chemistry of OXINE, a disinfecting product. It is composed of chlorine dioxide, sodium chlorite, and other oxychloro species. These components give OXINE the ability to disinfect, deodorize, sanitize, attack biofilms, and kill microbes. While chlorine dioxide is active, the other species in OXINE also contribute significantly to its high antimicrobial activity against various bacteria. OXINE is therefore more effective as a disinfectant than chlorine dioxide alone.
