Abstract

A gravity type thickener capable of providing an excellent thickening capability, being easily washed out due to excellent separability of sludge, and providing excellent corrosion resistance and durability, wherein sludge containing moisture is placed on a belt (4), and the belt is run to reduce the amount of the moisture in the sludge during the running so as to thicken the sludge, the belt is formed by knitting wire materials (4a, 4b), and the amount of the moisture reduced from the sludge is passed through clearances (4c, 4d, 4e) between the knitted wire materials for removal from the sludge.
