In the present study, the treatment of industrial wastewater and reuses for agriculture purpose. The photocatalytic degradation of dyes like bismarck brown Y dye has been used as technique for treatment in a batch reactor under solar light in heterogeneous slurry utilizing various concentrations of ZnO as photocatalysts semiconductors. Parameters has been studied (catalyst type, catalyst concentration, pH of dye solution and dye concentration at the beginning). The results show that the best dose of ZnO is 0.80 g/l, and the optimum pH is 10. The percentage removal of chemical oxygen demand (COD) of the dye solutions was higher than that of the degradation of dye for the same conditions of catalyst. Treated wastewater reuse in agriculture is a common practice in the Mediterranean countries and there is a considerable interest in the long-term effects of treated wastewater on crops intended for human consumption. This paper studies the fundamentals of agricultural irrigation using treated wastewater and the status of industrial wastewater reuse in Iraq with studies related to the effects on soils and plants.
