BILGE WATER TREATMENT WITH A TUBULAR ULTRAFILTRATION SYSTEM

Ultrafiltration is one of the candidate systems under evaluation for separation of oil from bilge water. A tubular ultrafiltration system using cellulosic and noncellulosic membranes was evaluated with a fuel oil, a lubricating oil, and bilge oil obtained from a YP (Patrol Craft). Permeate quality produced by both membrane types was very good because it was determined to be consistently less than 15 milligrams of oil per liter. Higher flux rates were achieved with the noncellulosic membrane. The cellulosic membrane, upon exposure to the YP bilge water, exhibited an irreversible flux decline. The noncellulosic membrane initially showed the same behavior, but a modification in the cleaning procedure provided complete restoration of flux. (Author)
