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.

This study investigated the alternative methods of wastewater disinfection. Areas of interest included methods of operation, ease of maintenance, and effectiveness for various types of wastewater. A literature search revealed three major disinfection options, which include: chlorination/ dechlorination, ultraviolet light, and ozone. A questionnaire was sent to the active duty Air Force installations that operate wastewater treatment plants, requesting permit limitations and monthly averages for a variety of wastewater parameters. The majority of Air Force wastewater treatment plants use chlorine for disinfection. Using the data obtained from the questionnaire responses and established wastewater parameters from other research, the basic design model equations were manipulated. The results showed that ultraviolet and ozone disinfection are safe alternatives to chlorine, however, ultraviolet systems appear to be better suited for the size and type of wastewater treatment plant that is typical of an Air Force installation.
