Title:

FILTRATION APPARATUS WITH FILTRATE RECOVERY DEVICE

Document Type and Number:

WIPO Patent Application WO/1996/000121

Kind Code:

A1

Abstract:

A filtration apparatus with a filtrate recovery device aims at shortening a period of time required for recovery of a stock solution in a tank, readily peeling sludge such as a filtration assistant or the like from filtration elements and discharging the same. After a pressurized water is introduced into a tank provided at upper and lower sides thereof with cylindrical-type filtration elements and plane-type filtration elements, respectively, to recover a stock solution as a filtrate, pressurized gases such as air and carbon dioxide are introduced from a side of the stock solution to discharge from the tank a water content remaining in the stock solution and to peel sludge from the respective filtration elements and discharge the same outside the tank.
