Abstract

In the wastewater treatment process of coagulation-flocculation-sedimentation, natural coagulants may be used to reduce turbidity. Manihot Esculenta (cassava peel) and Citrus Aurantium Dulcis (orange peel) were employed as natural coagulants for the treatment of Aponmu river. The best overall results were obtained when alum was partially replaced with cassava peel (70% AL30% CA), with all parameters (BOD; 6.1mg/L, COD; 9.9mg/L, hardness; 85.6mg/L, and Cu; 0.07mg/L, at pH of 6.3) meeting WHO drinking water standards and accepted practices for water and wastewater examination. However, alum's negative environmental effects on the production of non-biodegradable sludge and lingering effects on treated water are greatly reduced by partial substitution.
