Abstract
A sweeper assembly can include a plurality of holes drilled in one or more sweeper headers that can be angled downwards towards the basin floor to produce a gentle flow of fluid to keep particulate matter rolling along the basin floor. A centrifugal separator can include a curved velocity plate for smoothly directing flow from an inlet pipe to an inner wall of the separator and creating a downward vortex of particulate-laden fluid within the centrifugal separator. The centrifugal separator can include one or more reversal mechanisms for transferring particulate matter to a collection chamber and reversing the direction of particle-free fluid, which may upwardly exit through a discharge pipe. The centrifugal separator can include a bleed valve in the discharge pipe for automatically bleeding accumulated air in the “dead zone” between the inlet pipe and the top of the centrifugal separator.
