摘要
Red mud, a waste material obtained from aluminium factory in the processing of bauxite ore, has been used as flocculant in the treatment of dairy-waste water. Its efficiency is compared with the conventional flocculant, alum. Red mud removed 77, 71, 65,73 and 95 per cent of turbidity, BOD, COD, oil and grease, and bacterial count respectively at a dosage of 1304 mg per litre of effluent compared to 94, 80, 86 and 93 per cent respectively for alum treatment at a dosage of 476 mg per litre of effluent.
