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) 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, 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.
水资源短缺是一个全球公认的重大问题。为了解决水资源短缺问题，迫切需要通过废水处理实现水的再利用和循环利用。本研究旨在对经伽马辐照处理后的工业废水进行再利用。对工业园区的主排水渠进行了采样，并分析了其理化参数。处理时，施加了13千戈瑞（kGy）的钴（Co）辐照剂量。对处理后的水进行重新分析，以便与预处理分析结果进行比较，并符合国家环境质量标准（NEQS）。总悬浮固体（TSS）、生化需氧量（BOD）和化学需氧量（COD）分别下降了79%、81%和85%。所取得的结果在NEQS的允许范围内。得出的结论是，伽马辐射是一种处理工业废水的即时方法，在此推荐使用。
