From Product Design & Development, this article on energy recovery devices:

” … Historically in the U.S., desalination has been met with much controversy. Opponents think the process uses too much energy and is not good for the environment. These are antiquated arguments that were probably true 30 years ago.

Since then, technologies and processes have matured, and countries all over the world are relying on desalination for affordable, clean water.

The technology that turns sea water into drinking water is seawater reverse osmosis (SWRO), which squeezes drinking water from salt water using a semi-permeable membrane and high pressure.

SWRO has been around from many years, but has always been an expensive, energy-intensive and cost-prohibitive process. That was until the development of isobaric energy recovery devices (ERDs).

ERDs proved to be a game-changing innovation as the major technological breakthrough most responsible for reducing SWRO energy costs and enabling large-scale SWRO plants to operate all over the world. … “
