A reject chamber of a centrifugal cleaner and a centrifugal cleaner

An assembly comprising:

• a centrifugal cleaner including an inverted conical chamber;
• reject chamber at a lower region of the centrifugal cleaner and configured to receive rejects from the flow moving through the inverted conical centrifugal cleaner;
• a dilution channel extending into the reject chamber, wherein the dilution channel includes a flow path configured to receive a flow of dilution liquid and at least one dilution nozzle,
• an annular space within the reject chamber formed between at least one inner wall of the dilution channel and the dilution chamber;
• a reject outlet extending from a lower region of the reject chamber,
• wherein the at least one dilution nozzle includes at least one upward oriented dilution nozzle configured to discharge a flow of the dilution fluid into the annular space at an upward angle with respect to a horizontal plane.
