Abstract

Apparatus for separating contaminant from water, the contaminant being of lower density than water. The apparatus comprises a settlement chamber, initial separating means, and an entry port for introducing the liquid to be separated into the initial separating means for flow therethrough into the settlement chamber. A contaminant outlet opens from an upper region of the settlement chamber. A pump intake is located towards the lowermost part of the settlement chamber, and feeds a pump. The outlet from the pump is directed to a molecular separation filter capable of separating water from contaminant. Water discharges from the molecular separation filter, and can be further treated by an optional activated carbon filter. Contaminant leaving the molecular separation filter is directed back into the initial separating means.
