ABSTRACT:
A fluid level control apparatus for selectively controlling the movement of liquid flowing out of a flotation cell is described. The fluid level control apparatus is significantly reduced in size in comparison with the flotation cell or cells to which it is connected which enables less expensive construction and reduced operating costs in terms of both the equipment and the plant as a whole. The fluid level control apparatus comprises a vessel having a valve positioned therein which includes a valve body structured with a curved surface which provides selective and finite control of fluid flowing through the vessel of the control apparatus. In one embodiment at least one of the inlet and outlet of the control apparatus exhibit a cross-sectional area taken transverse to the intended fluid flow therethrough having a substantially horizontal dimension which is greater than a substantially vertical dimension.
