ERI, Water Standard Partner for Ship Desalination

Energy Recovery, Inc., a designer and developer of energy recovery devices for desalination, recently announced that Water Standard, a global vessel-based water desalination company, plans to use the PX Pressure Exchangerä (PXä) device in its first Seawater Desalination Vessel (SDV).

Water Standard builds and operates vessels that deliver desalinated water to clients onshore and to the offshore energy industry in response to the world’s growing water needs.

“ERI’s PX energy recovery device allows us to convert seawater to drinking water more affordably,” said Amanda Brock, chief executive officer of Water Standard. “Water production cost is a key metric to the success of our initiative, and ERI is a great partner to help improve desalination economics. ERI’s PX technology, which is capable of improving desalination energy costs by up to 60 percent, is field-proven and reliable.”

By integrating reverse osmosis water treatment technology and proprietary water intake and discharge systems in its Seawater Desalination Vessel design, Water Standard provides a mobile, cost-effective and environmentally responsible solution to provide water where needed and address severe water shortages.

The SDV can produce from 20,000 to 200,000m3/d (roughly 5 to 50 mgd) from 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 carbon dioxide per year.
