ABSTRACT:
A housing for a bilge pump-filter has a lower part in which oil and like light pollutants are separated from the polluted water. A pump has its intake connected to the lower region of this lower part and its output connected to an upper compartment of a compensation chamber in the upper housing part which is subdivided by a filter into this upper compartment and a lower compartment. A funnel under the filter conducts liquid coming down through the filter by gravity to the lower region of the lower compartment and a drain at the upper region of this lower compartment off the filter water. A level detector in the lower separation chamber operates the pump only when liquid level in this separation chamber is above a predetermined minimum level.
