Abstract

Greywater approach is gearing up an exercise of sustainable management solution by felicitous treatment approach reaching to recycle and reuse. This study is based on a hybrid electrocoagulation investigations on the removal performance of COD, Turbidity, chloride, TSS, Sulphate present in greywater. Effect of current voltage with respect to electrolysis time were performed to optimize the electrocoagulation process with combination of Al-Fe-Al-Fe and was found to be capable of promoting the treatment and reuse facility, with removal efficiencies reaching to above 90% in all final effluents of GW with 24 volts supply. Laboratory experiments were analyzed with EC followed by sand filters and GAC (Granular Activated Carbon) to achieve adequate quality of GW reuse. According to results, final effluents from all the combination, the highest removal efficiencies (COD : 93.51% TSS: 96.23, Turbidity: 94.59) was achieved. This investigation approach highlights the electrocoagulation and filtration studies that can be considered as one of the feasible treatment option for low strength greywater.
