As in Ashqelon turn sea water into drinking water

Station pumps in the water supply network of 120 million cubic meters of desalinated water per year. Staff — 57, a work process is continuous, 24 hours. The power consumption is 52 MW a year.

Sea water flows through pipes (gravity) at the stage of preliminary purification. Stage of pretreatment includes sand filters coarse and fine filters.

Purified sea water supplied to the desalting stage. Under the pressure of 60-70 atmospheres, sea water is "squeezed" through the membrane and is divided into 2 fractions: water without salts (40%) and brine (60%). Energy is returned to the beginning of the process. This cyclical nature allows for the reuse up to 50% energy. The diaphragms are made of highly durable polymer, the term of the bellows 7 years at the station are used simultaneously 45 thousand membranes.

The process of turning sea water into fresh takes 30 minutes.

Brine diluted wastewater, which was used for the cooling and is discharged into the sea. Performs permanent control of the quality of sea water in a radius of 300 m from the point of discharge diluted brine. In addition, studies of the status and diversity of marine flora and fauna.The results of monitoring, not seen a harmful effect on the marine ecosystem.

Demineralized water which its quality is close to distilled water, is fed to stage of mineralization. At this stage, demineralised water is added all the essential minerals that the water met the standard for drinking water.

Desalinated water is supplied to the local treatment plant, there is mixed with tap water and, only then, falls into the water distribution system and delivered to the consumer.
