Worlds largest desalination plant Ras Alkhair, Saoudi Arabia

This largest clean water plant in Ras Alkhair in Saudi Arabia, is based on reverse osmosis desalination.

The installation has started since 2014 and is supplying 1 million cubic meters of drinking water every day. It uses 2400 MW of power for the desalination processes.

The installation has been built hybrid with 8 evaporators and17 reverse osmosis units.

Total municipal water use in Saudi Arabia has been estimated at 2.28 cubic kilometers per year in 2010, or 13% of total water use. Agriculture accounts for 83% of water use and industry for only 4%.

It is tentatively estimated that average water consumption for those connected to the network is about 235 liters per capita per day.

Sorek 16′ vertical membranes

Israel

The largest non-thermal desalination plant in Sorek Israel. This reverse osmosis plant was started in 2013 and has a capacity of 624,000 m3 / day.

The 16″ membranes, in this arrangement, have a flow rate of 4.3 times more water than 8″ membranes (at the same feed pressure and operation conditions).

The estimate water use per person per year is 90 cubic meter, corresponding to 247 liters per day.

    Saudi Arabia relies most on desalination – mostly of seawater. The US is in second place. It uses mainly brackish and waste water although later this year it will open one of the world’s largest seawater desalination plants in Carlsbad, San Diego.

    In many places there is no alternative – certainly the Middle East and places like Singapore, the Canary Islands and the Caribbean have to look to the sea. Those that have a choice, like Europe and the US, China, Japan, will try conservation and reuse and brackish treatment and use [seawater] desalination as a way to top-up and provide some drought-proofing.
