More Complete Oil/Water Separation

The Abanaki Oil Concentrator provides virtually complete oil/water separation for recycling or disposal of either liquid.

Under most operating conditions, Abanaki skimmers pick up oil with only small traces of water. However, as surface oil is reduced to a thin layer (1/16 inch thick or less), more water (or coolant) may be picked up along with the oil. When used in tandem with an oil skimmer, the Oil Concentrator solves this problem by providing final phase separation. The result is water (or coolant) available for recycling, and virtually water-free oil for disposal.

The Oil Concentrator is non-electrical and contains no moving parts — it simply receives liquid directly from the skimmer. Based on the principle of gravity separation, the Oil Concentrator tank comes in three sizes so that there is adequate dwell time for the oil and water to separate. Water discharge is through a tube that has an open end near the bottom of the Concentrator, while oil flow is through a separate drain port near the top. As additional liquid enters the Concentrator, water and oil are forced out through their respective disposal tubes.

Installed at the discharge end of the oil skimmer, the Concentrator comes complete with mounting bracket, removable sludge screen and drain plug for easy cleaning. An optional thermostatically controlled heater is available for use with thick oils, or when the application is in freezing temperatures. (A heater should not be used in environments where explosive fumes might be present.)

Abanaki recommends the use of the Concentrator with all oil skimmers. It increases the efficiency of the skimmer and reduces costs associated with oil disposal.
