The treatment and disinfection of water for drinking continues to be a major public health issue. It is clear that disinfection methods involving chlorine compounds result in the formation of byproducts that constitute a health risk. The proposed work addresses the removal of the humate and fulvate precursors for the disinfection byproducts (DBPs) with inexpensive anion exchange materials. The goal is to develop a process that utilizes inorganic materials that are reasonably thermally stable and can, therefore, be regenerated easily. This process can effect complete removal of the precursor humic substances present in the water and will be economically competitive with activated carbon and membrane filtration.
