영문 초록

The objective of this investigation was to evaluate applicability of precoat filtration that can be substituted for rapid sand filter of conventional water treatment system(CWTS). Precoat filter used in this experiment are candle filter. Element disk of candle are pore size 10 mm(R), 20 mm(B) And diatomaceous earth are cake pore size 3.5 mm(Standard Super- Cel; A), 7 mm(Hyflo Super-Cel; B) and 17 mm(Celite 545RV; C). 2 kg/m2 diatomaceous earth is used for precoating, it coated candle in 5~6 mm thickness.1. Al adsorption dosages by diatomaceous earth used in experimental are Hyflo Super-Cel 0.843mg/g, Standard Super-Cel 0.782 mg/g and Celite 545RV 0.766 mg/g.2. Filtrate of precoat filter during 60min are R-C combination 20.7(m3/m2)> B-C 18.3(m3/m2)> B-B 15.0(m3/m2)> R-B 12.9(m3/m2)> R-A 11,093(l/m2).3. Water quality of precoat filter effluent are thus. KMnO4 consumption are 1.10~2.20 mg/l, removal rate are 30.9~65.6%. They are R-A 1.10(mg/l)(removal rate 65.6%), R-C(2.20 mg/l)(removal rate 30.9%). 4. Al3+ are not detected with all combination, removal rate 100%.5. Considering water quality and flux, continued running time of R-A combination is 7 hr. Accumulated filtrate are 74.4 m3/m2, average flux is 177.2 l/m2 · min. And filtrate per diatomaceous earth 1 g are 37.2 l. 6. R-A effluent s water quality are KMnO4 Consumption 1.10(mg/l), DOC 1.161 mg/l, Al 0.0 mg/l, UV254 0.016/cm, Turbidity 0.1(NTU). R-A combination is suitable to precoat filtration for the settling basin effluent treatment.
