The use ofPolyferricsulfate(PFS) flocculation, followed by  pumice  filtration, reduced the levels of resin acids, colour and 5 Day biochemical oxygen demand(BOD5)in pond 1 water by more than 90% and appears to at least as effective as the existing secondary treatment system. This Observation  indicate that primary flocculation/filtration technology could be as least as efficient as the existing secondary system process for resin acid, 5 Day biochemical oxygen demand(BOD5)and turbidity removal and more effective for colour removal. Preliminary cost estimates also indicate its probable cost effectiveness; this could be improved by the possibility of recovery or partial recovery and reuse of the flocculating agent.

Keywords   : biological treatment system, flocculating agent, 5 Day biochemical oxygen demand (BOD5),pumice filtration, colour  and resin acids
