【 摘 要 】

The ability of four inorganic coagulants namely; aluminum sulphate octadecahydrate (Al2 (SO4)2.18H2O), ammonium aluminum sulphate dodecahydrate (NH4Al(SO4)2.12H2O), ammonium ferrous sulphate ((NH4)2Fe(SO4)2.6H2O) and ferrous sulphate (FeSO4) was investigated to alter the amounts of turbidity, electrical conductivity, and chemical oxygen demand (COD) in wastewater. Results obtained from experiments indicated that maximum turbidity removal was achieved using FeSO4 (98.5) at 180 mins, while ((NH4)2Fe(SO4)2.6H2O) presented the overall least removal rate. The best COD removal (90%) was also achieved at 150 mins using ((NH4)2Fe(SO4)2.6H2O). It was observed that application of the coagulants didn’t completely eliminate COD from the wastewater, while the electrical conductivity was slightly affected by the four coagulants.
