    Abstract: A method of recovering oil from an oil well includes recovering an oil-water mixture from the oil well and separating produced water from the oil-water mixture. Thereafter, the produced water is directed through a ceramic membrane that removes free oil and emulsified oil from the produced water. The method or process further includes cleaning the ceramic membrane in online and offline modes. In the offline mode, cleaning is achieved by periodically backflushing the ceramic membrane with an aqueous media having a pH of 13 or greater and a temperature of 60°C or greater. Further, the ceramic membrane is cleaned in the offline mode by applying the following operations. In one or more clean-in-place operations, an aqueous alkaline media at a pH of 13 or higher and a temperature of 60°C or higher is directed through the ceramic membrane. In one or more clean-in-place operations, the ceramic membrane is also cleaned with an aqueous acidic media that contains dissolved citric acid. Finally, in one or more clean- in-place operations, a liquid hydrocarbon is directed through the ceramic membrane.

    Abstract: A method of concentrating the solids of a liquid suspension by providing a pressure differential across the walls of permeable, hollow membranes (6) immersed in the liquid suspension (9). The liquid suspension (9) is applied to the outer surface of the porous hollow membranes (6) to induce and sustain filtration through the membrane walls (12) wherein some of the liquid suspension passes through the walls (12) of the membranes (6) to be drawn off as clarified liquid or permeate from the hollow membrane lumens (11), and at least some of the solids are retained on or in the hollow membranes (6) or otherwise as suspended solids within the liquid (9) surrounding the membranes (6). The method includes periodically backwashing the membrane pores using the permeate by applying a gas at a pressure below the bubble point to the membrane lumens (11) to progressively displace at least some of the liquid permeate within the lumens (11) through the membrane pores resulting in removal the solids retained on or in the hollow membranes into the bulk liquid (9) surrounding the membranes (6).
