Abstract
PURPOSE: To continuously transfer the granular filtration material in a stable mode by securing water level in a cylinder above an necessary level through the mechanism wherein a closed circuit connecting a discharge pipe line of polluted waste water obtained by washing the granular filtration material and a liquid portion of a filter cylinder is provided and the polluted waste water is returned to a liquid portion of a cylinder by an automatic valve when the supply of a stock solution is stopped.
CONSTITUTION: A granular filtration material is slowly reached to a transfer chamber 3 and passed a transfer tube 4 by a lifting action of air 13, thereafter introduced to a regeneration and separation cylinder 5 of a filter material of which the bottom is connected to the upper edge of filter layer and suspended solid containing polluted waste water 7 and the granular filter material 6 are separated. When a stock solution is supplied, the water level is positioned at a of the figure A and a float 11 lighter than water is floated and functions as a valve to close a closed circuit 12. When the supply of a stock water is stopped, the water level of a main body position at a of the figure B is slowly lowered to a position b and a float 11 is dropped to open a closed circuit 12, then waste water 7 is flowed through a circuit 12 to a collector tank 9. Accordingly, waste water 7 forms a circulating passage along with a body 1 and the water level of the body 1 is not lowered below the predetermined position b.
