TREATMENT OF CHEMICAL AND MECHANICAL DIESEL OIL-WATER EMULSIONS BY ULTRAFILTRATION MEMBRANES

Two commercially available ultrafiltration membranes, Abcor, Inc. type HFA (cellulosic) and HFD (noncellulosic) in a tubular configuration, were tested for the treatment of oily water emulsions containing diesel oil, nonionic detergent and fine sand particles. Limited tests with lubricating oil were also conducted. Oil concentrations in the feed ranged from 1 to 25 percent by volume, while suspended sand particles and detergent loadings, when present, were 50 and 1000 ppm, respectively. Permeate flux was found to be dependent upon the feed flow rate, the level of contaminants in the feed, and membrane type. Average permeate fluxes over 24-hr operation, at 60 psig and 100 F, ranged from 40 to 100 gpd/sq ft. The HFA membrane exhibited superior permeate quality, yielding less than 10 ppm oil in all cases. Flux decline with time was observed, as expected. However, complete flux recovery was achieved through membrane cleaning.
