| Abstract |
The permeability of membrane filtration system depends on characteristics of the raw water and operating conditions. The purpose of this study was to determine the optimum operation parameters for water treatment using plate type MF membrane(pore size 0.22㎛). The pilot microfiltraion(MF) membrane separation system had been operated in a dead-end filtration mode and applied to actual Pal-dang raw water. The experimental results are shown as follows; (1)permeate flux 30LMH was determined the optimum operation condition, (2)the chemical cleaning efficiency was only found to be 100% using "H₂SO₄+NaOCl", (3)the removal efficiencies of SS and turbidity were found to be almost 100%. However, The removal efficiencies of UV_(260) and DOC were 30% and 13%, respectively. Also, in order to improve the permeate flux and the removal efficiency of dissolved organic matter, granular activated carbon system should be added to the MF membrane System. |
