DOWNLOAD EBOOKIn response to current and anticipated disinfection by-product (DBP) regulations, many utilities have begun to use chloramines as a secondary disinfectant. Chloramination produces DBPs such as haloacetic acids (HAAs), trihalomethanes (THMs), and haloacetonitriles (HANs) in lower concentrations than chlorination. Previous research has demonstrated that dihalogenated haloacetic acids (DXAAs) are the most commonly formed HAAs during chloramination. Some utilities may have difficulty meeting the new maximum contaminant level (MCL) for HAAs because chloramination does not limit the formation of DXAAs to the same extent as it does other DBPs. The objectives of this project were to: better understand the reactivity of key natural organic matter (NOM) fractions and the effects of treatment processes with respect to dihaloacetic acid (DXAA) formation, better delineate the influence of pH and Cl2/N ratio on DXAA formation, characterize DXAA formation kinetics and the impact of treatment processes on the kinetics, especially the impact of prechlorination, calculate the rate and extent of DXAA formation at elevated summer water temperatures, and determine the effect of bromide concentration on DXAA speciation and kinetics.

DOWNLOAD EBOOKBased on new primary and secondary drinking water standards, this detailed manual presents water treatment methods that are considered the "best available technology" by the U.S. Environmental Protection Agency (EPA). It examines the design of water supplies for membrane water treatment plants, including reverse osmosis, membrane filtration, and electrodialysis methods, and it explains process design and the water quality problems associated with each process. It also considers significant aspects of membrane process and groundwater and surface water supply development. Information necessary to operate water supplies and evaluate problems in the system are provided, in addition to specific well construction details necessary for the water wells used to supply membrane plants.
