ALC - Abanaki

Abanaki offers industrial wastewater skimmers specially designed for steel mills where plant maintenance engineers are looking for the lowest cost, most reliable method of removing greases and heavy oils from the steel-mill scale pit. Abanaki oil skimmers use the difference in specific gravity and surface tension between grease and water, allowing the belt to attract grease and oil 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.

Sometimes, an important technological advance begins with a small step-back! Such is the case with remediation of hydrocarbons from groundwater utilizing existing recovery and monitoring wells.

Choosing an oil skimmer best suited for your application will maximize oil removal while minimizing capital outlay and oil skimmer operating costs. There are 5 crucial steps that need to be considered when purchasing a skimmer for your application. Skipping one or any of these concepts can result in having zero success in removing oil from your waste water. So, let’s keep that from happening and go over these 5 simple steps!

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.

Oil skimming usually beats ultra-filtration systems in many applications. More often than not, installing large, complicated systems to remedy oil problems will not provide ideal results. You can save costs by using a relatively inexpensive oil skimming system to handle the free-floating oil and then a smaller treatment system to handle the oil that has remained suspended in the wastewater.

The location, shape, and capacity of a tank or water impoundment are major factors in choosing the right oil skimmer. Also consider fluctuations in water level, turbulence and possible emulsions. Although oil skimmers do not cause emulsions, they can have trouble removing certain types.

Oil skimmers usually incur a low initial cost, install easily, offer rugged construction, reliable operation and minimal upkeep. Training personnel for operation, monitoring and routine maintenance is nil.

Choosing an oil skimmer best suited for your application will maximize oil removal while minimizing capital outlay and oil skimming operation costs. In selecting an oil skimmer is to know what you need or expect your removal capacity to be.

There are several things to consider when choosing a belt or tube material for your oil skimmer. Some plastics will not stand up to heat or strong chemicals. Certain metal belts will not skim coolants effectively. Smooth belts do no pick up floating emulsified oils. Specific plastic belts do not last in heated applications, while other types of plastic belts will.

What is the maximum amount of oil to be removed, and the shortest period of time available to do it? Capacity should be based on the maximum amount of oil to be removed within the shortest available time. For instance, total oil influx may be 200 gallons in a 24-hour period, which averages about 8.3 gallons per hour. But if most of it comes during a single 8-hour plant shift, you will probably need a removal rate that is three times as high, especially if you are trying to prevent an unwanted discharge of contaminated water to a sewer system. As a rule-of-thumb, specify approximately twice the maximum capacity you anticipate needing for normal conditions.
