ABSTRACT:
Water from existing clarifier tank is pumped to a centrifugal separator where solid particles are removed. A bypass valve is disposed between the outlet of the separator and the inlet of the pump to keep the separator operating at high velocity even when there is little or no demand for processed water. A vortex breaker is provided at the sludge outlet of the separator to prevent solid particles from being carried to the processed water outlet to the separator. A valve is provided at the outlet of the vortex breaker to prevent vacuum lock when the pump is turned off, and a priming valve is provided to prime the pump. A float tank and check valve may also be provided for expelling trapped air from the system. Two or more centrifugal separators may be employed in parallel when a higher volume of processed water is required.
