Abstract-- This work include the photocatalytic degradation of biological ,and chemical treatment processes have been an aqueous crystal violet [Tris((dimethylamino)phenyl) employed to treat industrial wastewaters such as chemical , methylium chloride] dyes by using ZnO catalyst photo catalyst in biological, food ,pharmaceutical , paper, dye processing, and aqueous medium, Photocatalytic degradation of dyes was carried textile(4,5) .Physical methods include precipitation rain, out by using UV radiation as light source. The result of this study adsorption, and reverse osmosis. expressed by current diffusion against time to using Biological methods including anaerobic and aerobic treatment. polarographic technique. The effect of some parameters, such as Chemical methods via oxidation and reduction, Advanced mass of catalyst, Initial dye concentration, initial pH of aqueous dye solution and temperature were studied. oxidation
