An oil skimmer is a machine that removes floating oil and grease from liquid. Specifically, the floating oil adheres to skimming media, such as a belt, tube, rope, mop, or disk. Then, the media runs back to the machine to be wiped clean. Additionally, weir style skimmers use a pump to collect floating oils.
An oil skimmer is a mechanical device designed to remove floating oil from the surface of water or other liquids. Because oil is lighter than water, it rises to the surface — and that’s where skimmers do their job.
Whether in an industrial sump, a coolant tank, or an open body of water after a spill, oil skimmers help separate and recover this surface oil for reuse or disposal. Consequently, this process not only keeps systems clean but also prevents environmental contamination and regulatory violations.
Oil and water mixtures derived from manufacturing processes and food processing facilities that are held in large holding tanks or pits. In these applications, oil is usually removed by an oil skimmer or it can be pumped out for disposal. Skimming the floating oils with little water content can reduce the cost of disposal and lower the contingent liabilities of industrial wastewater discharge.
Oil Grabber Model 8 Belt Oil Skimmer
The Abanaki Model 8 Oil Grabber is a dependable and effective means of removing oil from water and water-base solutions. Often, belt oil skimmers alone will reduce oil to an acceptable level of water purity. Depending on the characteristics of the liquid, it is possible for the Model 8 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 coalescing systems.
The Model 8 belt oil skimmer utilizes a continuous belt and wiper to remove up to 40 gallons of oil per hour from the fluid surface. The belt, operating on a motor and pulley system, runs through contaminated liquid to pick up oil from the surface. After traveling over the head pulley, the belt passes through tandem wiper blades where oil is scraped off both sides of the belt and discharged. The tail pulley has flanges which allow it to roll freely on the inside of the belt without becoming dislodged.
It requires no bearings and does not need to be fastened to the tank. If turbulent conditions exist, an optional tether and cage assembly prevents the tail pulley 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 belt skimmer to attract oil and other hydrocarbon liquids from the surface of the fluid. The Model 8 can be used in tanks with depths as shallow as one foot, or as deep as 100 feet.
