Reject chamber of a centrifugal cleaner and a centrifugal cleaner

A centrifugal cleaner assembly comprising:

• a centrifugal cleaner including an inverted conical chamber;
• and
• a reject chamber assembly removably attached to a lower region of the centrifugal cleaner, wherein the reject chamber assembly includes:
• a reject chamber at least partially below the inverted conical chamber configured to receive rejects from a 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 dilution liquid and nozzles below the inverted conical chamber, wherein the nozzles are configured to discharge the dilution liquid from the flow path directly into an annular space within the reject chamber, wherein the annular space is below the inverted conical chamber and formed between at least one outer wall of the dilution channel and at least one inner wall of the reject chamber;
• and
• a reject outlet extending from a lower region of the reject chamber,
• wherein the nozzles include at least one upwardly oriented dilution nozzle configured to discharge the dilution fluid directly into the annular space at an upward angle with respect to a horizontal plane.
