Oil skimming is the most reliable and lowest cost method of removing food greases and oils from process wastewater. An oil skimmer uses the difference in specific gravity between oil and water, allowing the oil skimmer belt to attract frying oils, vegetable oils, greases, and animal fats as the belt passes through the surface of the water. The simple belt-and-motor approach is proven to operate unattended and reliably for decades with little maintenance.
Processors need to limit oils discharged into the environment, and recaptured greases and oils can be used to manufacture other products such as pet food. An Abanaki oil skimmer will help you accomplish both goals.
