This study was done to evaluate the performance of coconut fiber based organic filter in the primary treatment of swine wastewater (SWW). For each 100 L of SWW filtered, following parameters were determined in effluent: electrical conductivity and pH, concentration of total solids (TS), dissolved, suspended, fixed, and volatile solids, total nitrogen, phosphorus, potassium and sodium. The pH of the effluent during the first 100 L decreased, but then remained neutral until the end. The filter removed 30% nitrogen and about 70% phosphorous, but removal of sodium and potassium was inefficient, and in general their concentration increased. Of the physical parameters, 75% of TS, 40 to 60% suspended and volatile solids, about 40% total fixed solids were removed by the filter. The removal of dissolved solids was inefficient, but the SWW had lower salinity and about 20% lower electrical conductivity.
