First Water Standard vessel will use ERI units

Water Standard plans to use the PX Pressure Exchanger energy-recovery device made by Energy Recovery Inc (ERI) in its first Seawater Desalination Vessel (SDV), the two companies announced on 19 May 2009. Florida-based Water Standard builds and operates vessels that deliver desalinated water to clients onshore and to the offshore energy industry.

SDVs can produce 20,000-200,000m³ /day and can be based on any floating water platform, including ships or barges, depending on the water requirements in the affected region. ERI estimates that its PX technology will save Water Standard 34 MW and improve the carbon footprint of its vessels by 142,000 tons of CO2 per year.
