Abstract
The concentration and nature of natural organic matter (NOM) influence the processes selected for water treatment plants. Water supplies containing NOM dominated by humic substances require careful design and operation of the chemical pre-treatment step of coagulation. Humic substances in untreated waters exert a greater demand for chemical coagulants compared to particulate matter, and their removal is important for health reasons because they are precursors to trihalomethanes and other disinfection by-products. Furthermore, coagulation affects the performance of downstream particle separation processes of clarification (sedimentation or flotation) and filtration.
