Abstract:Applying inorganic metal salt-based aluminium sulphate (Al2(SO4)3) or alum in wastewater treatment has gained many concerns regarding the impact on health and environmental implications. Due to the negative consequences, incorporating inorganic and natural flocculants in the coagulation-flocculation process is the alternative way to reduce undesirable effects. In this study, an evaluation performance of Manihot esculenta (ME) starch and alum as a dual flocculant was conducted to remove chemical oxygen demand (… Show more
