RECOVERY OF FLOATING OIL ROTATING DISK TYPE SKIMMER

Laboratory tests indicated the feasibility of recovering 50,000 gal. of oil per hour using a series of powered metal cylinders approximately 7 ft. in diameter and 12 ft long. Testing included various oils ranging from light diesel oil to Bunker 'C' grade oil. Oil spread as thinly as 1.5 mm in thickness was amenable to collection, but recovery efficiency greatly improved with increased thickness. Herding of the oil with booms, as well as current, whether natural or caused by towing the disc unit through the oil, were shown to increase the oil thickness. Oil starvation, in the form of insufficient oil contacting the disc was shown to be a significant problem, but recovered oil still contained only around 2 percent moisture, eliminating the need for a separator. Wave action was shown to actually enhance pick-up.
