A method and apparatus for increasing the yield in the separating of heavy or light contamination from a liquid. The liquid is separated into accepts and rejects and the rejects outlet (8, 37) from the separator (1) opens into a rejects chamber (7) which forms part of a rejects loop. The loop includes valves (11, 12, 20) and a pump (15) which enable the pressure in the rejects chamber to be controlled so that there is substantially no flow of accepts from the separator to the rejects chamber, whilst the contaminant rejects are allowed to pass from the separator to the rejects chamber. The reject loop preferably includes an auxiliary separator (16) for removing contaminants from the loop. |
