Treatment performance of household wastewater in fixed bed submerged filter by polypropylene media

The purposes of the experimental project were to modify (FBSF) to compare plastic media form Small Pall Ring Bio-media Filter are commercially available. The model of FBSF consists of Equalization tank (EQ) Aeration tank with . The corresponding with Hydraulic Retention Time (HRT) 48 hrs. The factors used in the study are the essential parameter such as BOD COD SS TDS and changes in the Physical Characteristics of wastewater. polypropylene as a supporting media for Fixed Bed Submerged Filter polypropylene media 2 tanks Aeration tank with plastic media 2 tanks and Effluent tank The result experimental indicated that efficiencies of FBSF with 92.78% 75.90% 96.75% and 20.76%0 respectively gave the higher effluent values that the plastic media the efficiencies 84.20% 61.66% 94.12% and 14.80% 0. The effluent BODwas less than 20 mg/l. The was on clear less sediment no foul odor. The . polypropylene media in term of BOD COD SS and TDS removal of FBSF with of BOD COD SS and TDS removal of respectivelywastewater Fixed Bed Submerged Filter was effectively for the community household wastewater5 Rajamangala University of Teehnology Phra Nakhon
