Abstract

The objective of this investigation was to evaluate applicability of precoat filtration for drinking water treatment. Precoat filter used in this experiment are candle filter. Element disk of candle used in this experiment are pore size 5$\mu\textrm{m}$(W), 10$\mu\textrm{m}$(R), 20$\mu\textrm{m}$(B) and 40$\mu\textrm{m}$(Y). And diatomaceous earth are cake pore size 3.5$\mu\textrm{m}$(A), 7$\mu\textrm{m}$(B) and 17$\mu\textrm{m}$(C). Filtrate of precoat filter during 30min are R-C 11.3, B-C 10.2, W-C 8.9, Y-C 8.6, Y-B 7.1, R-A 5.4(㎥/㎡). Turbidity of the effluent can be attained under 0.1NTU with the all combination.
