PURPOSE: A filtering apparatus is provided to improve the efficiency of filtering and backwashing by controlling the pressures of feed water and backwashing water in the apparatus. CONSTITUTION: A filtering apparatus(100) includes a first penetrated hole and a second penetrated hole. An intermediate plate is arranged between the first penetrated hole and the second penetrated hole. A first water path and a second water path are formed at the upper side and the lower side of the intermediate plate. A plurality of layers of filtering plates(110) is stacked. A first through hole is formed at the filtering plate stack in order to connect the first water path and the first penetrated hole. A second through hole is formed at the filtering plate stack in order to connect the second water path and the second penetrated hole. Filleting fabric is combined in a part between the filtering plates. The upper side of the filtering plate stack is blocked by a first finishing plate(130). A second finishing plate(140) is combined with the lower side of the filtering plate stack. Discharging pipes(150, 160) are connected with the penetrated holes. |
