Protec and Dow Water to supply components for Carlsbad Desalination Project in US

IDE Technologies has selected pressure vessels and reverse osmosis membranes from Protec Arisawa and Dow Water & Process Solutions for the Carlsbad Desalination Project in San Diego, California, US.

The reverse osmosis membranes from Dow will be used as filters to separate salt and other impurities from water molecules during the desalination process.

Protec’s fibre-reinforced plastic pressure vessels for membrane filtration systems will be used to house the Dow membranes.

Poseidon vice-president Peter MacLaggan said: "Protec and Dow are recognised world-leaders in reverse osmosis technology.

"We are pleased to partner with such reputable innovators in the industry to provide this critical technology for the Carlsbad Desalination Project."

IDE is the contractor and operator of the plant owned by Poseidon Water.

Expected to be operational by late 2015, the facility will supply fresh drinking water to almost 112,000 local households, under a $1bn water purchase agreement signed by Poseidon with San Diego County Water Authority. Poseidon will supply water to San Diego from Carlsbad for 30 years.

Poseidon Water said it has been trying to involve local companies, such as Protec, for the construction of the desalination project in order to support the regional economy. It has created nearly 2,500 jobs in the region.
