Muhammad, N., R. Sinha, C. Patterson, AND V. Namboodiri. Comparative Evaluation of Alternative Disinfectants for Drinking Water and Wastewater Treatment. Presented at World Environmental & Water Resources Congress (EWRI 2013), Cincinnati, OH, May 19 - 23, 2013.
Impact/Purpose:
While traditional hypochlorite-based chlorine disinfectants are both potent and cost-effective, issues associated with handling hazards and the generation of regulated disinfection by-products (DBPs), have led to the search for alternative disinfectants.
Description:
The Water Supply and Water Resources Division (WSWRD) of the U.S. Environmental Protection Agency’s (EPA) National Risk Management Research Laboratory (NRMRL) initiated a research program to evaluate the performance of various disinfectants that could potentially be used in drinking water and wastewater treatment. Alternative disinfectants/disinfection procedures including TwinOxide™ and Peracetic Acid (PAA) have been tested in bench-scale/pilot studies at U.S. EPA’s Test & Evaluation (T&E) Facility in Cincinnati, Ohio for disinfection of E. coli, B. subtilis and B. globigii. This presentation summarizes the performance of the alternative disinfectants in disinfection of the aforementioned microorganisms and production of harmful disinfection byproducts (DBP) in different studies. The presentation also addresses field application procedures and the suitability of the disinfectants for water and wastewater treatment.
