The solution to turn seawater into fresh water uses less energy

Turning seawater into clean, drinkable water is one solution to meet the growing global demand for water.

Turning seawater into clean, drinkable water is one solution to meet the growing global demand for water. However, the desalination process, which involves removing salt and other minerals from seawater, is very energy intensive. To overcome this problem, the Norwegian company Waterise recently announced that it has a solution.

Removing salt from seawater consumes a lot of energy. Yet there are many people around the world who rely on this process to live every day.

Norway-based Waterise has developed a deep water treatment method that it says can cut energy consumption for seawater desalination by up to 40%.

RO or reverse osmosis is a technology that pushes water through a fine membrane to separate salt. This process also requires a lot of energy, but the difference is that it can draw water from hundreds of feet below the sea.

Waterise representative said the company’s technology also uses hydrostatic pressure. Water pressure is proportional to depth, so typically quite a bit of energy is used to direct seawater to land. However, Waterise’s new technology makes this job easier.
