Abstract
A coarse media flocculator utilizes buoyant media restrained against upward movement in a flocculator chamber whose cross-sectional area increases uniformly in the direction of vertical flow, thereby providing a uniformly tapering velocity gradient. The height of the media bed within the chamber is alterable, thereby changing its depth and cross-sectional characteristics within the tapered chamber. The velocity gradients of the flocculator can thus be changed independent of flow. The media restrainer comprises interlocked cooperating gratings each respectively joined to an opposite wall of the flocculator housing by a tracking mechainsm. Upon manipulation of a motor device, one grating is horizontally extended or retracted, producing a lowering or raising of the restrainer as its cross-sectional area is respectively enlarged or reduced. During this alteration of the area and elevation of the restrainer, which takes place in a smooth continuous manner, the cross-section and vertical height of the media bed constrained therebeneath are simultaneously varied, with a consequent adjustment of the flocculation parameters of the media bed.
