Treatment of Effluent from the Olefin Unit of Marun ‎Petrochemical Complex Using Advanced ‎Photocatalytic Oxidation Method

The urgent need for water in industries and the large volume of wastewater discharge has prioritized wastewater treatment and water recycling in the research and operational projects of various public and private companies. In this context, Marun Petrochemical Company has established a treatment plant to recover water from its wastewater, aiming to not only provide part of its water needs through treated effluent, but also to reduce disposal costs and wastewater-related issues. This study uses a batch slurry photoreactor for laboratory-scale experiments. The statistical results of this study show that reducing pH and increasing catalyst concentration lead to higher Chemical Oxygen Demand (COD) removal. In addition, it was revealed that increasing the amount of co-oxidant results in further COD reduction at higher pH levels is attributed to a strong antagonistic interaction between the pH and co-oxidant parameters.
