Document Type and Number:
WIPO Patent Application WO/2006/036014
Kind Code:
A1
Abstract:
A coagulation-separation apparatus has a coagulation-separation tank (1). Raw water flows from a mixing tank (2) to a coagulation-separation tank (1) through a raw water introduction pipe (3), a facility (4) for adding a high specific gravity material and a raw water introduction pipe (5). The coagulation-separation tank (1) is provided with a water-flow generator which agitates water to be treated to generate a water flow. The coagulation-separation tank (1) has a discharge port (13) for a sludge and a box (14) for collecting sludge in the lower portion thereof, wherein a sludge inside the box (14) for collecting sludge is transferred to a separator (8) through a sludge transfer pipe (15). The separator (8) is used for separating a high specific gravity material (9) from the sludge and supplying it to the facility (4) for adding a high specific gravity material.
