TwinOxide is a powder composed of two stable components: calcium peroxide and sodium percarbonate. It releases hydrogen peroxide when mixed with water. TwinOxide is used as a disinfectant and oxidizing agent in water and wastewater treatment. It provides an alternative to traditional chlorine-based disinfection, as it releases hydrogen peroxide, which is less harsh and has a milder odor. It is effective against bacteria, viruses, algae, and other organic contaminants.
