Reduction of Strength of Domestic Wastewater Using Natural Fibrous Materials

Abstract

The natural fibrous materials which are effective in purification purpose has been identified and used for domestic purification. The materials used as a filter bed in this study are Sisal fiber, Areca husk fiber activated carbon and river sand. The removal efficiency of these materials has been studied by setting the filter bed for different contact period. Influent greywater sample (raw water) and effluent greywater smaple (treated water) collected and analyzed for pH, TDS, TSS, TH, BOD, COD, oil and grease, chloride and sulphate in the laboratory and compared with THPCB and WHO standards. The removal efficiency of this parameter is between 0 to 25 are 12.5% (TDS), between 30 to 40 are 50% (TH, BOD, COD, sulphate) and 40 to 50 are 25% (TSS, oil and grease) and above 50 are 12.5% (Chloride).
