Title
Articles / The Study on the Efficiency Improvement of the Direct Filtration (1)
이태관Tae Gwan Lee
Abstract
This study was designed to experimentally investigate the relationship between the turbidity of the raw water and the size of the filtering media in an attempt to field application of the direct filtration. The turbidity was simulated by using Kaolin with up to 100 ㎎/ℓ under the given condition and the filtration was effective up to D=1.0㎜ media used. It was found that the amount of the added coagulant gave a significant effect on the pattern of filtered particulate. More added coagulant accelerated the surface filtration, and less added coagulant rendered, the deep filtration which retarded the operating time.
