NOM-removal by the SIX®-process
Some waters can have elevated concentrations of dissolved organic carbon (DOC), especially sources like surface waters that are under the influence of secondary effluent, recreation, heavy population, farming and industry. In a number of locations in North-West Europe, for example the United Kingdom and Scandinavia, DOC levels are increasing over time most likely due to climate change effects a...
متن کاملPredicting NOM Removal by Fixed-Bed GAC Adsorbers
Natural Organic Matter (NOM) normally exists in raw surface water as a complex mixture of organic compounds, mainly humic acids and fulvic acids. In water treatment plants, free chlorine reacts with NOM and forms a wide range of substances known as Disinfection Byproducts (DBPs). Granular Activated Carbon (GAC) adsorption is one of the best available technologies employed for the removal of NOM...
متن کاملExperimental Application of an Advanced Separation Process for NOM Removal from Surface Drinking Water Supply
Natural organic matter (NOM) in drinking water supplies significantly impacts on water supply quality and treatment, due to observed reactivity with many dissolved and particulate species. Several technologies are used nowadays to remove NOM from the water supply. The evolution of water-related directives, and progressively more restrictive standards for drinking water, however, call for the in...

Enhanced coagulation: its effect on NOM removal and chemical costs
hlorine is the most widely used oxidant in the United States for water disinfection. But chlorine reacts with the natural organic matter (NOM) that remains after treatment and forms halogenated by-products. Only some of these by-products have been identified, such as trihalomethanes (THMs) and haloacetic acids (HAAs), which are suspected to be human carcinogens. In 1979 the US Environmental Pro...
