Abstract

The aim of this study was to enhance of the Discfilter process (maximum treatment capacity - 500 ton/day) removal efficiency for small-scale wastewater reclamation under various influent wastewater conditions (with / without coagulation process, coagulant content and temperature). The result of chemical resistance test for fiber filter in the Discfilter that weight loss was obtained with 0.535% under pH 3, 0.092% under pH 9 and 0.028% under 10% NaClO. The removal efficiency test of Discfilter process on the with / without coagulation process showed that with coagulation process condition was occurred COD_Mn of 42.26 ± 0.61, BOD₅ of 88.72 ± 0.44, T-P of 84.67 ± 0.72 and SS of 90.58 ± 0.61. The removal efficiency of Discfilter process on the coagulant content (4.5, 5.0 and 5.0 mL/min) and temperature (< 10℃, 10℃~ 20℃ and > 20℃) conditions were increased as coagulant content and temperature increased. This study demonstrated the potential application of Discfilter process for small-scale wastewater reclamation.
