Separation of Oil from Bilge Water I. Bilge Water Characteristics and the Interaction of Bilge Water with Chemically Modified Surfaces.

Abstract

We report on the results of a project using surface characterization and novel surface-modification techniques to address the issues of developing a minimally fouling ceramic membrane filter. We have studied the physical characteristics of a synthetic bilge water mixture, examined the surfaces of the ceramic filters for evidence of fouling, and identified several surface modifications that, under laboratory conditions, work well in prevention of foulants. These surfaces, surprisingly, include hydrophobic as well as polar coatings. For the bilge water, it was discovered that detergent, at certain concentrations, may be useful in separating and coalescing oil droplets from the bilge water. Based on the results of the studies, several strategies for optimizing the removal of oil from water are suggested.
