Abstract

Moringa oleifera has been proven as an active, safe and inexpensive alternative for conventional coagulants that can be widely used for the drinking water treatment. Experiments were carried out in completely randomized design for drinking water sampled from Yangpu river at shanghai city to investigate the effect of Moringa extract and its combined use with Poly aluminum Chloride (PAC) on turbidity and TOC removal. A jar test apparatus was employed for the tests, with the optimum pH level maintained between the ranges of 7 to 7.5, and initial water turbidity of 61 NTU. The optimum dosages of PAC and Moringa were 30 mg/L and 300 mg/L respectively, while half dosage of each was employed for the combined use. The results of turbidity removal were found to be 96.1%, 68.6% and 95.7% to attain final turbidity of 2.4, 19.2 and 2.7 NTU for PAC, Moringa and their combination respectively. Whereas for TOC removal, various dosages of Moringa were applied at 0, 200, 300, 400, 500 and 600 mg/L and the results showed that concentration of TOC in water increased considerably with the increase in Moringa dosages, whereas the combination of Moringa and PAC minimized the negative effect of Moringa on TOC in water significantly.
