Abstract: A compound multi effect distillation (MED) system of integrated backward and forward fed MED systems. Heated concentrate from the hottest effect of the backward fed MED system is delivered as feed to the hottest effect in the forward fed MED system, to generate a more concentrated brine than possible using any of the systems alone. Furthermore, coupling the systems creates additional operational advantages and increases distillation efficiency.

Abstract: An evaporator having more efficient heat transfer tubes, that are either or both coated and vertically corrugated. The coating, though reducing the heat transfer co-efficient, lengthens the time between cleaning treatment to increase the overall efficiency of the evaporator. The corrugation of the tubes controls the film characteristics and enhances evaporation from the film upon condensation of vapor within the tubes. The corrugation profile is selected to enhance waviness and turbulence of the films and thereby increase evaporation and condensation and hence the effectivity of the evaporator.

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.

Abstract: A multi-effect evaporator, having an upstream and a downstream end, adapted for distillation of water. It comprises a plurality of effects connected in a series manner and arranged into groups. Each group has a common parallel water feed inlet adapted to supply all effects in the group with feed water. The evaporator further includes a main feed water line in fluid communication with the most upstream group. An array of heaters is disposed along the line, adapted for heating the feed water before its entry into the effects of the latter group. Each effect comprises means for forwarding the second outlet vapor into one of the heaters for heating the feed water. Each group comprises a pump adapted to extract the concentrate from the effects of the group and pump it into the common parallel water feed of an adjacent downstream group.

Abstract: A method of cleaning a fouled RO membrane in a module for RO separation, the membrane having feed side and permeate side, the foulant accumulating at the feed side. The cleaning method comprises: feeding concentrated saline solution to the feed side of the RO membrane under the high gauge pressure of the normal RO separation process; feeding dilute saline solution to the permeate side of the RO membrane under higher pressure than the permeate pressure of the normal RO process, so that a net driving differential ΔPN is directed to the feed side, whereby the solvent is being sucked from the permeate side to the feed side, penetrates into the interface between the membrane and the accumulated foulant, and separates the foulant from the membrane surface; and withdrawing the concentrated saline solution together with the separated foulant and the penetrated solvent from the feed side of the RO membrane.
