||Coagulation of Mississippi River water improved the removal of total organic carbon (TOC) and trihalomethane precursors by granular activated carbon. The increased removal is thought to be due to the reductions in TOC and in poorly adsorbed higher-molecular-weight organics that are achieved by coagulation. A cost analysis indicated that very high coagulant dosages would be needed during pretreatment to minimize the overall costs of chemical treatment.
