Functionalized cationic polyamines and their use to reduce the NDMA formation during the treatment of aqueous systems, and applications in the water treatment industry, including wastewater and drinking water treatment processes

摘要

New water treatment chemicals and corresponding water treatment or more generally aqueous systems treatment processes are provided, which greatly attenuate the NDMA problem, that is, decrease the formation of NDMA during the water or aqueous system treatment namely in the presence of a disinfectant, and decrease too the level of NDMA in the so treated water of aqueous system, and in the end products such as drinking water.
