The contamination of water with organic compounds has become an increasing concern in today's world. The cost-effective and sustainable treatment of industrial wastewaters is a major challenge. Advanced treatment techniques such as electrocoagulation-electroflotation offer economic and reliable solutions for the treatment of industrial wastewater. In this study, the electrocoagulation-electroflotation method was investigated for the simultaneous removal of chemical oxygen demand, total phosphorus, total Kjeldahl nitrogen, and color via response surface methodology. Factors such as electrode combination (Fe and Al), current density (10-20 mA/cm), pH (3.0-9.0), and electrode distance (1-3 cm) were investigated in the treatment of wastewater to obtain maximum treatment efficiency. It was determined that chemical oxygen demand, total Kjeldahl nitrogen, total phosphorus, and color removal reached up to 94.0%, 77.5%, 97.0%, and 99.0%, respectively. Treatment costs were found as $0.71 with the Al-Fe electrode combination.
水中有机化合物的污染已成为当今世界日益关注的问题。具有成本效益和可持续性的工业废水处理是一项重大挑战。电凝聚-电浮选等先进处理技术为工业废水的处理提供了经济可靠的解决方案。在这项研究中，通过响应面法研究了电凝聚-电浮选法同时去除化学需氧量、总磷、总凯氏氮和色度。研究了电极组合（Fe 和 Al）、电流密度（10-20 mA/cm）、pH 值（3.0-9.0）和电极距离（1-3 cm）等因素对废水处理的影响，以获得最大的处理效率。结果表明，化学需氧量、总凯氏氮、总磷和色度的去除率分别高达 94.0%、77.5%、97.0%和 99.0%。使用 Al-Fe 电极组合时，处理成本为 0.71 美元。
