Studies regarding the application and effectiveness of brackish and seawater desalination to augment drinking water supplies have focused primarily on pretreatment challenges, process optimization, energy efficiency and concentrate management; however, less has been documented with regards to post-treatment requirements, water quality and secondary impacts. The behavior of desalinated water in the distribution system remains largely undocumented, and potential issues that may arise after introducing desalinated water into existing distribution systems include impacts on internal corrosion control, disinfectants and disinfection byproducts, hydraulics, infrastructure maintenance, water quality, aesthetics, and customer acceptance. This article discusses the post-treatment of synthetic membrane processes used for desalting drinking water supplies. Includes 62 references, table, figures.
