(57) In one form, the present invention is a Batch Centrifugal Concentrator adapted to mitigate the adverse effects associated with dirty feedwater including a rotary bowl having means to clear solid particulate matter in a high velocity flow stream. In another form, the present invention is a seal assembly adapted for use with a batch centrifugal concentrator. The seal assembly including a non-rotating lower portion and a rotating upper portion. The non-rotating lower portion includes a water in/out port, and the rotating upper portion includes a water in/out port. Each port is interconnected by a conduit that is adapted to enable fluid to flow into, through and out of the seal assembly. A gap is provided between the said lower and upper portions. The stationary portion includes an air inlet port that is adapted to create and maintain a zone of positive pressure within said gap.
