Photo catalytic technologies paired with nanochemicals are used in the research study to treat oil-produced water. Because solar energy is copious and available across the Sultanate of Oman all year, it is considered the best alternative for processing oil produced. In recent years, the photo catalytic approach has shown a lot of promise as a low-cost, long-term therapy that is also good for the environment. Zinc oxide (ZnO) is used as a photocatalyst because of its great photo catalytic activity, photo-stability, broad band gap, and low toxicity. Its photo catalytic activity to eliminate organic pollutants in oil-generated water was investigated. According to the results of the experiment, ZnO can be employed as a possible catalyst in wastewater treatment. pH, TDS, conductivity, salinity, DO, TOC, and COD were all used to evaluate the performance of the ZnO. The results revealed that TOC fell for the first 3 hours and thereafter remained steady, indicating that 3 hours is the optimal response period. However, after 5 hours of exposure to sun light, a continual reduction in COD and turbidity was observed.
