Abstract:

The effluent outflow from a shipboard oilwater separator is further reduced in oil content by passage through ultrafiltration membranes arranged in series as an added down stream treatment prior to overboard discharge. Effluent from the oilwater 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.
