Effluent discharge from the processing or formulating industries of pesticides and agricultural runoff are major sources of environmental pesticides, and wastewater from the pesticide industry is a major treatment for the aquatic system. Various photodegradation techniques via Solar, Solar / TiO2, UV and UV / TiO2 processes have carried out photocatalytic degradation of Ziram on wastewater. In order to improve the operating parameters, such as pH , initial concentration, catalyst dosage and contact time, studies have also been carried out. The UV / TiO2 photo catalytic process was found to be more efficient than any other methods studied for Ziram degradation. For initial pH 5, initial Ziram concentration of 20 mg / l and TiO2 dosage of 1 g / l, the maximum degradation of Ziram at 300 minutes was 92.7 percent. For UV / TiO2, the kinetic constant (k) was found to be 9.62 times greater than the solar / TiO2 method and 8.19 times greater than the UV method.
