ABSTRACT:
A single enclosure includes a reaction zone and a decanting zone. Water to be treated is introduced into the bottom of the reaction zone. A pump turbulently mixes the water and sludge within a turbulent area of the reaction zone and passes the resultant mixture through a central passage at a rate several times higher than the rate at which the water is introduced into the reaction zone. A first portion of the mixture is recycled back into the turbulent area. A second portion of the mixture, including a relatively high concentration of sludge, is distributed to the bottom of the decanting zone, at a flow rate and at a pressure sufficient to ensure that the mixture of sludge and water will be distributed uniformly throughout the entire area of the lower portion of the decanting zone. The purified water passes upwardly through the decanting zone and is collected. The sludge settles downwardly to the bottom of the decanting zone and is returned to the turbulent area of the reaction zone.
