Abstract

PURPOSE: To enable both of a filtration process and a backwashing process to be carried out with a device of simple construction by connecting an internally provided hollow filter medium of a star shape in cross sectional face, and a filtrate storage tank provided in the upper part thereof, and performing backwashing by making use of head pressure.
CONSTITUTION: The liquid to be treated is pressure-fed into a vessel 1 by driving a pump 5A, and is filtered by a filter medium 4. The filtrate ascends into a filtrate storage tank 3A via the communicating hole 2A of a partition chamber 2 from the inside of the filter medium 4, and is discharged from a discharge pipe 8. When cake accumulates on the filter surface of the medium 4, and filtration efficiency drops to a fixed filtration pressure, the pump 5A is stopped by the signal of a pressure detector 7, whereby the pressure-feeding of the liquid to be treated is stopped. At the same time, a motor operated valve 6A is opened to discharge the liquid in the vessel 1 from a discharge pipe 6, and restores an atmospheric pressure in the vessel 1, thence the filtrate in the storage tank 3A is forced out onto the surface of the medium 4 by head pressure, whereby the cake accumulated on the surface is stripped off.
