Abstract
PURPOSE: To enable to filtrate simply and to highly dehydrate sludge without spoiling improved effects by transferring sludge after passages and tanks have been filled with water, and recovering water after predetermined time is elapsed.
CONSTITUTION: Sludge is introduced into a freezing-and-melting tank 2 and processed by a heat-exchanger 1 by means of freezing-and-melting process, then characteristics of the sludge in its grain size and settling are changed. Succeedingly, a valve 9 is opened, a pump 8 is operated and a dehydrating tank 4 and other containers, into which the sludge is scheduled to be transferred, are filled with water before a discharge port 3 is opened and the sludge is transferred into them. Then the sludge having improved characteristics is transferred through water slowly and without being given shock. When the discharge port 3 is opened, sludge sinks immediately through water and is accumulated on a filtrating cloth belt 5 in the dehydrating tank 4. Under this state, the pump 8 is operated again and water is sent back into a water tank 10.
