Desalination

Energy Recovery

Our Technology A watermaker or desalinator is a device used to obtain potable, drinkable water by reverse osmosis of seawater or brackish water. Reverse osmosis can be an energy-intensive process, that’s why we use an energy recovery pressure amplifier, making it possible to run your watermaker from a solar array, wind turbine, or battery bank. This pump lowers the amount of energy consumed by as much as 75% over conventional systems. How it works: Conventional Watermakers In a co...

General Information About Water Desalination

General Information About Water Desalination

Less than 1% of the global fresh water supply is potable. Seawater and brackish water can be converted to drinkable water through reverse osmosis.

While osmosis is a naturally occurring process where solvent molecules spontaneously enter through a semi-permeable membrane into a higher solute concentrate, reverse osmosis purification requires an external force to occur.

Reverse osmosis desalination is a process that purifies seawater or contaminated and undrinkable water sources by forcing water through a membrane, against osmotic pressure, leaving contaminants behind. The result is water devoid of dissolved salts and harmful content.

The seawater membranes used in desalination systems remove salt, bacteria, viruses, protozoa, and cysts, from the raw water. This produces fresh and potable water. Because of this, reverse osmosis is one of the most absolute purification processes, and is used by militaries, hospitals, and communities worldwide.
