Process efficiency characterization of plastic medium trickling filter

A laboratory scale pilot plant investigation was carried out to study the performance of a plastic medium trickling filter and to compare the treatment efficiency of this trickling filter with stone medium filter. Treatment efficiencies were studied at different hydraulic and organic loading rates. The result of this investigation indicates that the plastic medium trickling filters were more efficient than stone medium filters at the loadings in excess of 0.52 * 10 −6 kg BOD cubic meter per second. However, at low hydraulic and organic loadings stone media filter gave better performance than plastic filter.
