ABSTRACT:
A wastewater treatment system for treating wastewater containing undesirable pollutants which comprises a housing having a bottom and defining an internal chamber. The internal chamber is provided with a first and second baffle member which cooperate to define a mixing zone and a separation zone. Wastewater (containing a sufficient amount of air so that the air present in the wastewater exceeds the solubility of air in the wastewater) is introduced into the mixing zone of the internal chamber, and an aerated water is sprayed into the wastewater to produce a quantity of air bubbles sufficient to promote the flotation of pollutants having a density approximately equal to that of the wastewater to form a froth. Pollutants having a density substantially greater than the density of water settled to the bottom portion of the housing. An effluent reservoir assembly (which forms a reservoir zone) is spatially disposed from the second baffle member so that a quiescent zone is formed therebetween. The effluent reservoir assembly is provided with a fluid inlet opening and a fluid outlet opening and defines a fluid flow passageway between the reservoir zone, the first quiescent zone and the effluent discharge zone.
