摘要：

The reduction of pollution strength in palm oil mill effluent (POME) using five inorganic salts and nine polymers was investigated. Treatment of POME with 80-100 mg litre-1 of Magnafloc LT22 polymer aided in coagulation and flocculation of Total Suspended Solids, producing 96%, 63%, 53% and 93-94% reduction in the turbidity, chemical oxygen demand (COD). Total Solids (TS) and Total Suspended Solids (TSS) respectively, of the effluent. Treatment with 200 to 300 mg litre-1 FeCl3 + 70 to 100 mg litre-1 Magnafloc LT22 polymer reduced COD, TS and TSS by 47 to 53%, 43 to 49% and 92 to 94%, respectively. The TSS of POME can be substantially reduced by treating with coagulating and flocculating agents before discharging into other treatment systems.
