Protecting Membranes in Advanced Water Treatment: Effective Management of Chloramine and Peroxide Residuals

Chloramines and peroxide are used for biological fouling control and advanced oxidation in advanced water treatment, but both chemicals can have unintended impacts on membrane performance if not kept under control. This presentation shares practical insights for operating three types of membranes in a potable reuse process, with a view to the impacts of oxidants on UF, RO, and membrane contactor (MC) membranes. The presentation includes operating data from 12 months of process operations, and a process improvement that solved a sulfur turbidity problem, while reducing overall chemical costs.
