This study investigates the enhancement of electrocoagulation (EC) treatment of wastewater by adding mucilage extracted from Egyptian taro (Colocasia esculenta). EC is an efficient, eco-friendly method for removing pollutants such as total dissolved solids, total suspended solids (TSS), color, and chemical oxygen demand (COD) from wastewater. The research explores the effects of different operational parameters, including applied voltage, treatment time, and pH, on the efficiency of EC using iron/aluminum electrodes. Mucilage was added as an environmentally friendly additive to enhance removal efficiency. The study used a laboratory-scale setup with kinetic and thermodynamic analyses to evaluate the removal mechanisms. Results indicate that the addition of mucilage improved COD removal, while other parameters like color and TSS were better without additives. The findings demonstrate that mucilage can be a potential enhancer in wastewater treatment, with the Langmuir and Freundlich models applied to describe the adsorption process.
本研究调查了添加从埃及芋(芋属植物)中提取的黏液对电凝聚(EC)处理废水的强化作用。电凝聚是一种从废水中去除总溶解固体、总悬浮固体(TSS)、颜色和化学需氧量(COD)等污染物的高效、环保方法。该研究探讨了不同操作参数,包括施加电压、处理时间和pH值,对使用铁/铝电极的电凝聚效率的影响。黏液作为一种环境友好型添加剂被添加以提高去除效率。该研究采用实验室规模的装置,并进行动力学和热力学分析以评估去除机制。结果表明,添加黏液提高了COD的去除率,而在无添加剂的情况下,颜色和TSS等其他参数的去除效果更好。研究结果表明,黏液可能是废水处理中的一种潜在增强剂,应用朗缪尔和弗伦德利希模型来描述吸附过程。
