The Abanaki Model MB Oil skimmer is a dependable and effective means of removing oil from water and water-base solutions. Often, oil skimming by itself will reduce oil to an acceptable level of water purity. Depending on the characteristics of the liquid, it is possible for the Model MB alone to reduce oil content to less than five parts per million in water. The unit can be used as a pretreatment before filtration, and in conjunction with a coalescing system. The Model MB oil skimmer utilizes continuous belts and wipers to remove up to 200 gallons of oil per hour from the fluid surface. The belts, operating on a motor and pulley system, run through contaminated liquid to pick up oil from the surface. After traveling over the head pulley, the belts pass through tandem wiper blades where oil is scraped off both sides of each belt and discharged. The tail pulleys have flanges which allow them to roll freely on the inside of the belts without becoming dislodged. These lower pulleys require no bearings and do not need to be fastened to the tank. If turbulent conditions exist, an optional tether and cage assembly prevents the tail pulleys from being dislodged. Oil skimming makes use of the differences in specific gravity and surface tension between oil and water. These physical characteristics allow the belts to attract oil and other hydrocarbon liquids from the surface of the fluid. The Model MB Oil Skimmer can be used in tanks with depths as shallow as one foot or as deep as 100 feet.
