SEDIVORTEX - Grit Removal Systems

The SEDIVORTEX unit is installed in a circular concrete tank. The screened effluent enters into the tank by means of a suitable tangential inlet channel. A rotary paddle creates a vortex effect which settles the grit particles to the bottom of the grit trap. Air is blown through a pipe into the base of the airlift system. As this air rises through the central discharge pipe it carries the grit laden with liquid to a grit classifier. The effluent without grit goes out from the outlet channel situated in the upper chamber.
