Treatment of industrial wastewater with gamma irradiation for removal of organic load in terms of biological and chemical oxygen demand

Water scarcity is a known and major issue throughout the world. To tackle water scarcity, there is an urgent need for water re-use and recycling through wastewater treatment. This study is an attempt to re-used industrial effluent after treatment with gamma irradiation. The main drain of the industrial estate was sampled and analyzed for Physico-chemical parameters. For treatment, irradiation dose 13 Kilo Gray (kGy) cobalt (Co(60)) was applied. The treated water was re-analyzed for comparison with pre-analysis and compliance with the National environmental quality standard (NEQS). A decrease was observed in TSS, BOD(5), and COD with 79%, 81%, and 85% respectively. The results achieved are within the permissible limits of NEQS. It was concluded that gamma radiation is an instant method for industrial effluent and is herein recommended.
