| description | A secondary oxidation pond effluent was treated using hollow fibre crossflow
micro filtration and coagulation process. Preliminary experiments were carried out to
find optimum dosage of Moringa oleifera and alum as coagulants. Optimum dosage of
Moringa oleifera in treating low turbid (30-70 NTU) and high turbid (70-100 NTU)
secondary oxidation pond effluent was 100 mg/L respectively. About 50% turbidity
removal was achieved when using 100 mg/L Moringa oleifera. At optimum dosage of
200 mg/L of alum, 97% turbidity removal was achieved for high turbid samples while
93% turbidity removal was achieved for low turbid samples. Both Moringa oleifera and
alum were found to be more efficient in treating high turbid samples. However, alum
was more effective in removing turbidity in secondary oxidation pond effluent than
Moringa oleifera. Using 10,000 mg/L Moringa oleifera as a stock solution was more
suitable than using 5,000 mg/L and 20,000 mg/L Moringa oleifera in removing
turbidity in kaolin solution. Next, the performance of micro filtration coupled with coagulation using
optimum dosage of Moringa oleifera was investigated. Better flux performance and
lower rate of fouling were achieved when combining micro filtration with coagulation.
Pseudo-state flux at 3 L/m2.hr and constant suction pressure within 0.6 bar were
obtained after 300 hours of filtration time. Removal of COD, BOD5, alkalinity, residual
turbidity, TSS, VSS, TDS, TS, temperature and pH in filtrate were not influenced by
incorporation of coagulation using Moringa oleifera. Filtrate with quality lower than 50
-
mg/L COD, 25 mg/L BOD5, 2 mg CaCO3/L alkalinity, 1 NTU turbidity, 1 mg/L TSS
and VSS respectively was produced with micro filtration both with and without
coagulation. |
