ABSTRACT:
Decanter pond level or radius is adjusted incrementally by means of an annular retainer plate having an eccentric recess formed in the surface thereof which faces hub openings. The recess receives a plate dam slidably therewithin. Each retainer plate or retainer, typically 6 in number, is mounted over a hub opening. The dam is mounted over the hub opening such that its weir surface substantially coincides with the rotating pond level. By rotating the retainer around the prepositioned dam in increments preset in the retainer, the dam moves radially inwardly or outwardly depending upon the position of the recess eccentricity with respect to the hub opening. The dam is provided with two different weir surfaces, each usable with a different side of the dam, thus permitting the number of adjustments to the pond level to be doubled. A modification discloses infinite or stepless pond level adjustments.
