Bioelectrochemical cell (BeCC) integrated with Granular Activated Carbon (GAC) in treating spent caustic wastewater

The study is to treat spent caustic wastewater by using bioelectrochemical cell (BeCC) integrated with Granular Activated Carbon (GAC) as the bacterial attachment medium. BeCC is a bioelectrochemical reactor which employed microorganisms for substrate degradation, while also capable in producing ene...
