A water intake and pretreatment system () comprising an inlet for delivering water from a natural source to a reservoir (); said inlet to reservoir having a net screen () to prevent entry of organisms above a predetermined size and including a one-way gate () 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 () is included for localized backwashing of the granular filter media.

Environmentally friendly water intake and pretreatment system

According to one aspect of the present invention, there is provided a desalination system comprising a plurality of elongated pressure vessels (PV). Each PV has a longitudinal axis, oriented such that the longitudinal axis thereof is of a vertical orientation. Each of the PVs is adapted to receive therein a plurality n of desalination membranes. The membranes located above the lowermost membrane within the PV have a total weight allowing them to function as a mechanism limiting axial expansion of the lowermost membrane, whereby the PV is free of any additional limiting mechanism.
