Separation of Oil in Bilge Water by Semipermeable Membrane.
Abstract
The oil-separation characteristics of cellulose-acetate membranes were experimentally analyzed with a bench-scale apparatus. Experiments were initially conducted on distilled water solutions to determine permeate (product water) flux rate through the membrane as a function of operating time when the feedwater contained minimal impurities. A group of membrane separation experiments were then carried out with distilled water and 1% 2190-TEP lubricating oil. For the oil-water tests, the change in permeate flow rate with time and the oil concentration of the permeate, the feedwater, and the waste water were measured. The results of the oil-water tests showed that the oil concentration could be reduced from 10,000 to less than 25 parts per million in a single pass through the membrane. The primary difficulty was a gradual decrease in permeate flux rate that resulted from the membrane becoming coated with an oil film.
