Abstract: A method of operating a pressure-retarded osmosis plant, the plant comprising at least one osmosis element having a semi-permeable membrane, the semi-permeable membrane defining a feed side and a permeate side of the osmosis element, the method comprising, in a first mode of operation, supplying a feed stream having a relatively high concentration of solute to the feed side, supplying a permeate stream having a relatively low concentration of solute to an inlet of the permeate side, and receiving a feed outlet stream from the feed side wherein permeate has passed through the semi-permeable membrane from the permeate side to the feed side, in a second mode of operation, supplying a backwash stream having a relatively low concentration to the feed side of the osmosis element such that water passes through the semi-permeable membrane, and receiving a permeate outlet stream from an outlet of the permeate side, the method further comprising alternately performing the first mode of operation, to perform a production step, and performing the second mode of operation, to reduce fouling of the semi-permeable membrane.

Abstract: Combining flue gas treatment, and in particular CO2 sequestration, with hardening of reverse osmosis (RO) permeate. Flue gas is compressed and injected into pressurized water, being either cooling water or RO permeate. The water with dissolved CO2 is either dispensed into the sea for biological fixation of the CO2 or, in the case of RO permeate, mixed with limestone to harden the product water.
