Using peracetic acid as a disinfectant at Metro Vancouver's northwest Langley wastewater treatment plant

Description:Regulatory agencies in general are implementing more stringent requirements where chlorine is used as a disinfectant and encouraging treatment plants to consider alternative disinfection methods. Peracetic acid has successfully been used as a wastewater disinfectant in Europe and various plants in North America have also piloted its use. Of the North American plants, only Florida's St. Augustine Wastewater Treatment Plant has continued full scale with peracetic acid after their pilot. Metro Vancouver's Northwest Langley Wastewater Treatment Plant is a 12 MLD secondary plant, which has traditionally used sodium hypochlorite and sodium bisulfite for disinfection. The plant is currently in the midst of a pilot using peracetic acid as the primary disinfectant.
