Use this microbicide for municipal wastewater

| By Chemical Engineering

Proxitane WW-12 Peracetic Acid (PAA) is an environmentally compatible microbiocide that is used for biological control in municipal wastewaters. This U.S. Environmental Protection Agency (EPA)-registered wastewater disinfectant is an alternative to halogenated disinfectants such as chlorine-based chemicals, and can have an immediate positive synergistic effect on an existing ultraviolet (UV) disinfection system by simply adding it into the wastewater. Compared to dosage requirements for industrial-grade NaOCl, Proxitane WW-12 PAA is applied at a similar rate, does not require a dechlorination step, and does not form chlorinated byproducts. This company is collaborating with the EPA, under a cooperative research and development agreement (CRADA) to generate practical information regarding peracetic acid’s usefulness as a green alternative to chlorine-based water disinfectants to reduce disinfection byproducts. — Solvay Chemicals Inc., Houston
