PROCESS AND APPARATUS FOR WATER DECONTAMINATION

摘要

A method for removing N-nitroso-dimethylamme (NDMA) and its derivatives (e.g. dimethylamine) from water. The method combines ultra-violet irradiation and ozonation. Hydrogen peroxide may be added to the treated water during ozonation. The method allows also to remove volatile organic compounds present in the treated water and to destroy microorganisms. A modular sidestream injection apparatus used during the ozonation step.
