개량조건이 하수슬러지 탈수에 미치는 영향

다국어 초록 (Multilingual Abstract)

This study aimed to investigate the influence of the conditioning properties such as pH, mixing speed and reaction time on the dewaterability of sewage sludge and compare the performance with the derived conditions at the different solid concentrations. Performance parameters including time to filter test (TTF), specific resistance to filtration (SRF) and water content showed the optimum result at the pH value of 3, the rapid mixing speed of 200 rpm, and the slow reaction time of 20 min. In case of 20,000 mg/L of TS, a dosage of 1.0 g inorganic conditioner/L-sludge decreased TTF, SRF, water content of dewatered sludge cake, turbidity of the supernatant from 146 to 22 sec, 2.0 x 1014 to 0.4 x 1014 m/kg, 81.6 to 74.8% and 112 to 51 NTU, respectively.
