ABSTRACT:
The sweeping assembly performs the method of drawing impurity-laden liquid from a reservoir throughout the depth of a body of liquid. The assembly comprises a flotation section, a surface skimming section, an intermediate suction section, and a bottom sweep and suction section. The flotation section includes a floating assembly which supports the surface skimming section, the intermediate depth suction section and the bottom sweep and suction section therebelow within the liquid in the reservoir. The surface skimming section includes a mechanism for removing impurity-laden liquid from the surface of the liquid in the reservoir. The bottom sweep and suction section includes a mechanism for placing impurities from the bottom of the reservoir into suspension within the liquid body for drawing impurity-laden liquid from the bottom of the reservoir. The intermediate depth suction section includes an assembly for drawing impurity-laden liquid from an intermediate location within the liquid body at least from the middle half section between the top surface and the bottom of the liquid body.
