Abstract
A pump supplies water from a clarifier tank to a centrifugal separator, where solid particles are removed, and then to wash spray heads. A return or bypass conduit with a pressure-operated, modulating one-way valve permits water to pass from the outlet of the separator to the inlet of the pump in sufficient volume to ensure that the separator will operate at high velocity even when there is little or no demand for processed water at the spray heads as well as to recycle centrifuged water to further clean it. A float tank is coupled to and extends from the return conduit for enabling any trapped air to be expelled from the system. In addition, an air-bleeding conduit with a one-way check valve therein is placed in parallel with the return conduit to permit air flow in the direction opposite to that allowed by the valve therein to enable air to be removed from the system, especially when the pump is primed by supply of additional water thereto.
