ABSTRACT:
The effluent outflow from a shipboard oil/water separator is further reduced in oil content by passage through ultrafiltration membranes arranged in series as an added downstream treatment prior to overboard discharge. Effluent from the oil/water separator is buffered by delivery through a feed pump and use of a recirculation pump through which such downstream ultrafiltration treatment is subject to conditional flow control as well as periodic backflush cleansing of the filter membranes.
