    Abstract: 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.

    Abstract: Oxidizable contaminants in water are destroyed rapidly and efficiently by exposing the water to oxidizing conditions under pressure. Specifically, a single dose of hydrogen peroxide may be injected into the water, followed by the repeated injection and mixing of low doses of ozone. In each such high intensity mixing/reaction stage, ozone is injected at a pressure, velocity, and direction approximately matching that of the contaminated water flow. High intensity mixing under pressure facilitates rapid and complete oxidation of the contaminants with minimal stripping of volatile contaminants and waste of undissolved ozone. Residual ozone levels after high intensity mixing may be carefully monitored and minimized by adjusting the injection of hydrogen peroxide and ozone in order to suppress the formation of bromate. Additional contaminants may be removed by passing the treated water through activated carbon beds.
