Sea-water RO (SWRO) desalination requires around 3 kWh/m 3, much higher than those required for other forms of water supply, including RO treatment of wastewater, at 0.1 to 1 kWh/m 3. Up to 50% of the seawater input can be recovered as fresh water, though lower recovery rates may reduce membrane fouling and energy consumption.

Instead of using the static pressure of a water supply line to force the water through the filter, pressure is provided by a hand-operated pump. These devices can generate drinkable water from seawater. The Portable Aqua Unit for Lifesaving (short PAUL) is a portable ultrafiltration-based membrane water filter for humanitarian aid. It allows ...
