A coolant skimmer is a machine that removes floating oil and grease from liquid. The floating oil adheres to skimming media, such as a belt, tube, or disk. The media then runs back to the machine to be wiped clean.

For industrial oil skimming, there are six basic designs commonly used in moving media skimmers. (Suction skimmers are excluded, as they are generally unsuitable except for relatively thick (1/4 inch) layers of oil; otherwise they tend to ingest large amounts of water.)

Companies look for effective ways to remove oil from water or coolant to reduce costs and the liability of proper disposal. Another reason for removing the oil is a better work environment. Letting oil remain in the coolant tank allows anaerobic bacteria to grow. Anaerobic bacteria break down the components of coolant, causing it to need changing more frequently. Oil-laden coolant with a high anaerobic bacteria content has two other drawbacks as well. The first drawback is an unpleasant odor caused by the bacteria. The second drawback the smoke generated from the oil-laden coolant coming in contact with the operating cutting tool. One of the easiest ways to remove hydrocarbons from water or coolant is by using an oil skimmer. It is a low maintenance, easy to use tool for removing oil from water or coolant.

It is a common question asked every day by people in all fields of industry. Machine shops, steel mills, industrial manufacturers, and many others are faced with the problem of removing oils from coolants and wastewater on an everyday basis. They are faced with high disposal and maintenance costs. Some manufacturers are charged extreme amounts to have their contaminated water treated properly by their local water treatment facility.

The use of an oil skimmer in the machine shop setting holds many benefits. Removing the oil from a machine coolant tank will initiate some esthetic benefits such as cutting down on the amount of smoke generated from the cutting tool coming into contact with oil laden coolant.

When a machine is shut down for the weekend, oil has a chance to come to the surface of the coolant tank. Bacteria that are living in the coolant tank use up the dissolved oxygen in the coolant mix, a process that is sped up by having a layer of oil on the surface. This allows odor causing anaerobic bacteria to thrive, giving off that familiar “rotten egg” smell.

Choosing the right oil skimmer may improve the oil collection rate depending on the application. In a parts washer application, a belt skimmer is usually the best choice because of its small footprint and its ability to use various belt types to handle harsh conditions. Shallow wastewater sumps may have less than one foot of water, requiring a tube type oil skimmer that uses a tube that can float on the surface and collect the oil without bottoming out. Standard coolant sumps may be able to be cleaned up with an inexpensive disk skimmer while other sumps may have very little access. Some sumps can only be accessed with an oil skimmer that can bolt to the side of the tank and have a tube access the sump through a cutout in the side of the tank. If you’re not sure which skimmer would best suit your plant’s application, contact an Abanaki’s sales rep today and they’ll help determine which oil skimmer is right for your application!
