Abstract: A method for removing residual oil from oily water under pressure is provided. The method comprises flowing a liquid stream of an oily water downward through a vertically extended zone to remove the residual oil. A gas is injected into the lower end of the zone and at a rate sufficient to generate bubbles of a predetermined volume in the liquid stream. A sufficient pressure is maintained in the zone to control the rate of expansion of the bubbles to a volume compatible with oil droplets in the liquid stream during upward migration of the bubbles and the oil droplets. The rate of flow of the liquid stream from the lower end of the zone and the rate of flow of the gas from the upper end of the zone are regulated to collect residual oil from a quiescent volume within the upper portion of the zone.

Abstract: Improved skimmer apparatus for use in dissolved air floatation basins employed in water purification and waste water treatment plants is provided. The invention includes centrally positioned, longitudinal guide rails affixed to the basin and two or more interconnected reciprocating carriages, each carriage having a skimmer blade affixed thereto, the carriages being moveably mounted on the rails. At the effluent end of the basin is an upwardly shaped ramp, and the carriage nearest in proximity to the ramp has a ramp profile duplicating mechanism pivotally mounted to it. The carriages with attached skimmer blades are advanced at desired time and distance intervals advancing the sludge from the influent end of the basin toward the effluent end of the basin and the ramp, until the carriage having the ramp profile duplicating mechanism advances to and upwardly upon the ramp, the skimmer blade affixed thereto raising the sludge above the liquid level thereat, thereby removing excess liquid and depositing the sludge into a hopper for disposal. The skimming blades are then raised above the liquid/sludge surface and returned to the place of beginning and the skimming cycle is repeated.

Abstract: A method of, and apparatus for, separating phases in a polyphase system is described and particularly in separating oil from produced water by the contact of gas bubbles and oil droplets by a dispersed gas flotation technique. A polyphase system is divided into at least two portions. The pressure of one portion is reduced to form bubbles of a gas, and the two portions are then recombined whereby the bubbles in the mixture enhances flotation, and hence separation of the dispensed phase, e.g. oil, from the continuous phase, e.g. water. The invention has particular application in the oil industry and in other fields where efficient separation is required.

Abstract: In the improved system and method of the present invention, a batch of contaminated oil is deposited into a tank, with the oil preferably being passed through a filter during the depositing step to assist in removal of solids. Once the contaminated coolant has been deposited into the tank, the oil is agitated by injecting several streams of air into the bottom of the tank. This creates several bubble streams which pass upwardly through the coolant toward the surface and, during this passage, agitate the coolant and effect separation of the oil so that it rapidly rises to the coolant surface. The bubble streams are created by different sized orifice member whereby the bubbles of one stream are smaller than the bubbles in another stream. This causes differential agitation vertically through the mass of coolant, and also at the surface, whereby the tramp oil which rises to the surface tends to congregate within the small area disposed over the small bubble stream, thereby facilitating removal of the separated oil.

Abstract translation: 在本发明的改进的系统和方法中，将一批污染的油沉积到罐中，优选在沉积步骤期间通过过滤器以帮助去除固体。 一旦污染的冷却剂已经沉积到罐中，则通过将几股空气流注入罐的底部来搅动油。 这产生几个气泡流，其通过冷却剂向上通过表面，并且在该通道期间搅动冷却剂并且实现油的分离，使得其快速上升到冷却剂表面。 气泡流由不同尺寸的孔口构件产生，从而一个气流的气泡比另一个气流中的气泡小。 这导致通过冷却剂的质量以及在表面上的垂直方向的差别搅动，由此上升到表面的流出物倾向于聚集在设置在小气泡流上方的小区域内，从而便于去除分离的油。
