Treatment of landfill leachate wastewater by chemical coagulation-flocculation, electro-membrane bioreactor, and anaerobic hybrid system.

In this study, the treatment of landfill leachate wastewater by chemical coagulation, an electro-membrane bioreactor (e-MBR), and an anaerobic hybrid system was studied. First, chemical coagulation process was applied to landfill leachate wastewater, which is referred to their high organic pollutants. Aluminum sulfate (alum), poly aluminum chloride (PAC), ferric chloride (FeCl), and ferrous sulfate (FeSO) were used as coagulants.
