Abstract: A sea water intake system comprising a main sea water intake pipe, one end of the sea water intake pipe being provided with a centrifugal chamber, the chamber having at least one tangential inlet for entry of sea water to cause rotation of the sea water in the chamber. The other end of the intake pipe terminates in a sump, the sump having a water level lower than that of sea level and having a pump to transport sea water from the sump through a delivery pipe to a treatment plant. A central region of the centrifugal chamber is in fluid communication with a substantially vertical airlift pipe having an air inlet at, or close, to the chamber and a water exit remote from the chamber.

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.
