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.

Abstract: A treatment control system using a fluid using system wherein fluid is passed from the fluid using system during dump cycles occurring at periodic time intervals over a total dumping cycle. The fluid passed from the fluid using system during each dumping cycle is sampled and designated as a fluid dumping sample with each fluid dumping sample corresponding to the fluid passed from the fluid using system during one of the dump cycles. The total dissolved solids level in each of the fluid dumping samples is determined. Some of the dump cycles are designated as discharge cycles or treatment discharge cycles where the total dissolved solids level is above a predetermined high total dissolved solids level. Some of the dump cycles are designated as reuse cycles or treatment reuse cycles where the contaminant total dissolved solids level of the fluid dumping samples were determined to be below the predetermined high total dissolved solids level.
