Abstract: A system for cleaning feed water of variable quality, the system comprising an inlet for selectively delivering feed water to one or other of at least two feed chambers, each feed chamber having a delivery pipe for delivering feed water to a reverse osmosis or nanofiltration; a pump to deliver the feed water from one of the chambers through its associated delivery pipe to the reverse osmosis or nanofiltration to create a concentrated feed stream and a product water stream; return pipes for selectively returning the concentrated feed stream to one or other of the at least two feed chambers; a product water outlet for removal of the product water; and means for switching the delivery of the concentrated feed stream between the selectable return pipes upon detection of a predetermined reduction in efficiency within one or another of the feed chambers.

Abstract: A method and system for cleaning a multistage evaporator, the evaporator having a normal operational mode and a cleaning mode and having at least two groups of effects (2, 4), each group having one or more effects. In a normal operational mode, input vapor is introduced to a first group of effects (2), the first group comprising the hottest effects, and then vapor is delivered from the first group to a second group of effects (4), and optionally, from the second group of effects to a third group of effects (6) and so on depending on the total number of effects. Upon detection of a predetermined level of scale formation in the first group of effects, the evaporator is switched to a cleaning mode wherein the first group of effects (2) is physically separated from the other groups of effects and the input vapor is re-directed into the second group of effects (4). A cleaning agent is introduced into the physically separated first group of effects (2) until a predetermined level of cleanliness is achieved.

Abstract: A system for cleaning feed water of variable quality, the system comprising an inlet for selectively delivering feed water (FW) to one or other of at least two feed chambers (2,4), each feed chamber having a delivery pipe (2i, 4i) for delivering feed water to a reverse osmosis or nanofiltration (8); a pump (6) to deliver the feed water from one of the chambers (2, 4) through its as sociated delivery pipe (2i, 4i) to the reverse osmosis or nanofiltration (8) to create a concentrated feed stream and a product water stream (PW);return pipes (2R, 4R) for selectively returning the concentrated feed stream to one or other of the at least two feed chambers (2, 4); a product water outlet for removal of the product water (PW); and means for switching the delivery of the concen trated feed stream between the selectable return pipes (2R, 4R) upon detection of a predetermined reduction in the efficiency of the RO or NF process within one or other of the feed chambers (2, 4). The pressure of the concentrated feed stream is reduced to atmo spheric pressure prior to its delivery back to the chamber and the feed stream passes through a desaturation unit (20).
