Seawater Desalination Power Consumption

Seawater Desalination Power Consumption

Seawater desalination, like any other water treatment technology or separation processes, requires the use of energy to produce water. As a drinking water treatment technology, however, seawater desalination requires more energy than most other water treatment methods.

Often, however, the power consumption associated with seawater desalination is exaggerated or inaccurately represented, particularly when compared to other treatment technologies or alternatives assuring safe, reliable public water supply.

This paper reviews and outlines the power requirements associated with seawater desalination, measures used to compare and offset seawater desalination power consumption to other water supply alternatives, and the opportunities for future reduced energy demand.
