ABSTRACT:
This invention generally relates to an improved flotation apparatus and process for purifying a stream of effluent by forming a separable, buoyant floc out of the waste matter suspended in the effluent. The improved apparatus and process utilizes a mixing and floc dispersion means for intimately admixing the stream of effluent with a conditioning agent in a stream of tiny gas bubbles. The mixing and floc dispersion means also functions to dampen floc-sinking currents which are generated by the introduction of the stream of effluent into the flotation tank, and to uniformly disperse the resulting floc across the width of the tank. The mixing and floc dispersion means includes a series of at least two elongated, fluidly connected chambers, wherein the second chamber has a larger cross-sectional area than the first chamber.
