Safe drinking water and effluent have long been dependent on the large-scale use of chlorine. Process Safety Management (PSM) and the Risk Management Program (RMP), safety regulations now enforced by OSHA and EPA are leading to serious reconsideration of chlorination as the preferred disinfection method. Renewed concern about the safety of chlorination by-products is also driving water and wastewater specialists and plant personnel to consider alternatives to traditional chlorine application. Choosing Disinfection Alternatives for Water/Wastewater Treatment is a practical explanation of all available disinfection technologies in light of management criteria: legal compliance, plant safety, effuent quality, and cost. This text is designed for all who must understand and act on the challenge of finding safe and equally effective methods of wastwater and water disinfection besides traditional chlorination.
"…the ext contains a lot of practical, experience-based data that undoubtedly will serve anyone having to make a decision about the design or modification of a water or wastewater treatment plant."
