Description
A concise review of the standard treatmenttechnologies used to achieve compliance withthe Stage 2 Disinfectants/DisinfectionByproducts Rule (D/DBPR), along with theirrespective advantages and disadvantages, ispresented in this article. Capital and operatingcost estimates for D/DBPR compliance, firstreleased in 2005 by the U.S. EnvironmentalProtection Agency, are updated.As many utilities have found, switching toa disinfectant other than chlorine may beeffective in limiting regulated disinfection byproducts,but it can also create new DBPswhose effects are not well known or understood.Treatment technologies that removethe source of the byproducts, although moreexpensive, may prove to be the better alternative – especially when the additional contaminantremoval often required in additionto the reduction of DBPs is factored intothe equation.By implementing organic matter removaltechnologies, a water utility can best achieveStage 2 D/DBPR compliance without creatingadditional problems in the treated water andwill likely achieve additional benefits in termsof improved water quality. This article canhelp utilities prepare for technology selectionas well as future treatment needs and budgetingof expenses. Includes 15 references, tables.
