Abstract

Water for treatment is brought in at the bottom of the vessel where it passes through an ejector to entrain bed material which is carried up a vertical pipe to be returned to the top of the bed while the water runs down through the bed. Back washing is eliminated. The vessel can also be used as a granular filter unit.
