Electrocoagulation/electroflotation as a combined process for the laundry wastewater purification and reuse

•Electrocoagulation/ electroflotation methods allow for the simultaneous removal of surfactants, color, and turbidity.•The anode dissolution rate is a function of quantity of electricity and the water temperature.•Current density, pH, and treatment time have a significant effect on the wastewater cleaning.•The process under study appeared to be cost-effective for the laundry wastewater purification and reuse.•The study showed that economic effect of EC and EF processes is due to low electrical energy consumption.
