  • USE OF CHLORAMINES AND CATIONIC POLYMERS IN WATER TREATMENT
    Publication number: 20210387876
    Abstract: Methods to improve water treatment for industrial uses are described. One method involves admixing source water, such as from a river or other flowing source or body of water, with a at least one water-soluble cationic polymer and at least one chloramine and a coagulant and/or flocculant to provide a treated water. The at least one water-soluble cationic polymer and at least one chloramine are present in an effective amount to improve water treatment efficiency, such as in allowing use of reduced amounts of coagulant and/or flocculant, and/or reduced suspended solids, turbidity, and/or color clarification.
