Effects of current density and electrode material on the dewaterability of the thickened activated sludge by electro-flotation

BACKGROUND: Electro-flotation (EF) could improve thickening and subsequent dewatering characteristics of activated sludge although the settling characteristics of the sludge were very poor. The objectives of this study were to evaluate the performance of EF in the thickening and dewatering of activa...
