ABSTRACT:
The specification discloses a settling tank system adapted for low-turbulence settling of solids from water, said system comprising a circular tank for retention of water during settling, a radial boom provided at the level of the surface of the water for rotation around a central hub, means for rotating the boom, said boom having a leading edge and a trailing edge, said leading edge having a horizontal forwardly projecting shelf below the level of the water, said trailing edge having a horizontal rearwardly projecting shelf also below the level of the water, said leading edge shelf, trailing edge shelf and boom bottom presenting a smooth continuous surface for non-turbulent passage through the water, said trailing edge having a means for uniform and non-turbulent supply of solids-containing water to the length of the shelf at a volume rate equal to the rate of horizontal displacement of the forwardly moving boom, said leading edge having a means for uniform and non-turbulent removal of cleared water from the length of the shelf at a rate equal to the displacement of the forwardly moving boom.
