The large-scale removal of colloidal contaminants from artisanal activities was conducted through optimized bipolar electrocoagulation with lower energy consumption and aluminum sacrificial electrodes. As a result, over 90% simultaneous removal of total chromium, phosphorus, chemical oxygen demand and turbidity contents was achieved for relative short time (10–30 min), neutral pH of 7.0–7.5 and minimized current density. By optimization of the applied electrochemical parameters the elimination of carcinogenic colloidal chromium and organic mixture was modeled in a reproducible manner, and the reached purification levels of the effluents were acceptable for their reuse in the household. The practical usage of reported electrocoagulation design was successfully demonstrated as an effective alternative of the current conventional method for treatment of the tanning, domestic and artisanal industrial wastewater in Fez city, Morocco.

通过优化的双极电凝技术（具有较低的能耗）和铝牺牲电极，可以从手工活动中大规模去除胶体污染物。结果，在相对较短的时间（10-30分钟），中性pH值为7.0-7.5且电流密度最小的情况下，可以同时去除90％以上的总铬，磷，化学需氧量和浊度。通过优化所应用的电化学参数，以可重现的方式对致癌的胶体铬和有机混合物的消除进行了建模，废水达到的净化水平可以在家庭中重复使用。
