An oil-water and oil emulsion separation system using a plurality of transport vessels as the separation tanks. The containers or tanks are arranged in series with sludge or oil removed first and thereafter remaining oil is removed and finally a relatively pure aqueous solution is returned to the system. The unit is useful with parts washers or any apparatus with which water is contaminated by free oil or sludge. A floating skimmer is placed in the user's sump and a vacuum draws this into a series of containers in which it is processed and in which sludge and oil are successively separated. A positive displacement pump is used. A manifold having vacuum relief valves for at least one container is also provided. In one embodiment, flow restrictors are placed in at least one manifold.
