Pink water, a solution of trinitrotoluene TNT and other nitro-bodies is a major pollutant at AAPs which manufacture TNT and load, assemble and pack bombs and other ammunition. Two of the new technologies being investigated as alternatives to carbon adsorption, which is currently used to purify pink water, are covered in this report. One method involves the use of ultraviolet uv ozone the other, uv-oxidant. In the uv-ozone study, a pilot system with a volume of 3.79 cubic meters per day was evaluated. This system reduced dissolved TNT and RDX to less than one milligram per liter with no by-products requiring disposal. A larger, 18.9 cubic meter per day plant, is proposed. In evaluating the uv-oxidant process, commercially available uv-light, water-purification units were used in conjunction with oxidants such as hydrogen peroxide or oxone, a blend of potassium persulfate oxidants. Variables such as film depth, dilutions, uv wavelength, and operation of the units in series rather than in parallel, were examined in optimizing the system. Author
