An apparatus and method for removing foreign matter from a pool of liquid wherein a plurality of spaced nozzles are disposed in the opposite sidewalls of the pool for injecting streams of conically-shaped inoculum carrying liquid into the pool, the nozzles being arranged in the opposite sidewalls so that the outer surfaces of the streams from opposite nozzles intersect and slightly overlap such that the turbulence mixing regions of all the streams occupy approximately all of the liquid in the pool, with drain openings being located in the pool in those regions of least turbulence to remove the foreign matter from the pool. |
