    Abstract: A local backwashing apparatus 110 for a filtering system comprises an enclosure 119 having an open lower end, positionable above a surface of filter media 92 supported by a drainage layer 96. The enclosure is connected to a mechanical member (300, FIG. 6A) configured to force the enclosure into the filter media and release the force prior to the lower end of the enclosure contacting the drainage layer. The lower end of the enclosure being brought into contact with the drainage layer through a pressure differential between the interior and exterior of the enclosure. A pneumatic system such as an air pump, is in fluid communication with the upper part 127 of the enclosure and is configured to determine an air pressure therein. A pipe system connects the upper part of the enclosure with the pneumatic system and with a discharge structure 132. A control unit is connected to the pneumatic system. Also disclosed is a method of backwashing a filtering system. The backwashing apparatus may be used to pre-treat water.

    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 associated 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 concentrated 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 atmospheric pressure prior to its delivery back to the chamber and the feed stream passes through a desaturation unit (20).

    Abstract: A water intake and pretreatment system (10) comprising an inlet for delivering water from a natural source to a reservoir (12); said inlet to reservoir having a net screen (16) to prevent entry of organisms above a predetermined size and including a one-way gate (30) to allow organisms to exit the reservoir; said reservoir further comprising a granular filter media for water and algae filtration; and a drainage layer for removal of filtered water from the granular filter media to a drainage outlet. A local backwashing apparatus (40) is included for localized backwashing of the granular filter media.
