Claim 7:
8. The desalination system of claim 1, comprising:
one or more further partitioned containers, each housing a movable partition partitioning the container into an upstream compartment and a downstream compartment each of variable volume, each further partitioned container having a first inlet port at an upstream end of the container, a second inlet port at a downstream end of the container and an outlet port at the downstream end of the container;
one or more further membrane containers, each housing a cross-flow semipermeable membrane dividing the membrane container into a saline compartment and a desalinated water compartment, the saline compartment comprising first and second cross-flow ports, the desalinated water compartment comprising a desalinated water outlet port,
wherein the feed pump is connected to feed the supply of saline water to the first inlet port of each partitioned container, the recharge pump is connected between the second cross-flow port of each membrane container and the second inlet port of each partitioned container to feed saline water into the downstream compartment of each container, the main valve is connected between the outlet port of each partitioned container and the first cross-flow port of each membrane container, the bypass valve is connected on the one side to the inlet port of each partitioned container and on the other side to the second cross-flow port of each membrane container, and the purge valve is connected on the one side to the first cross-flow port of each membrane container.
