Design and Fabrication of Multi-Disc Oil Skimmer

Abstract

During the past 40 years, there have been numerous major accidents of oil spill in various countries, mostly as results of ship collisions. There are several methods in handling oil spill accident, in which the most effective methods are using mechanical oil skimmer with disc plate. This will reduce water pollution and saves the aquatic life. Disc type oil skimmer is used to remove the floating oil from liquid medium. The oil is removed from the metal disc and belt through wiping blades. Here we use the skimming medium as Metal disc. The skimming medium runs over the surface of water in which oil brought out with little amount of water. The main purpose of this fabricated skimmer is to purify the water from various dirt oils. The effectiveness of the oil skimmer on handling oil spills is influenced by various factors, such as the depth of the disc submerged or the disc surface area dipped into the oil spill, the area of the wiper sweep, the thickness of the oil on the disk surface, and the rotation speed of the disc. The present study is concerned to estimate the Oil Recovery Rate (ORR) and Oil Recovery Efficiency (ORE). The disc speed, depth of immersion and film thickness are the operating parameters. Speed of the disc can be varied by providing multispeed arrangement. The skimmer is more cost efficient and simple in design in comparing to costly treatments like membrane filters and chemical treatments.
