Water filters and purifiers can remove pathogens and sometimes chemicals from fresh water, but they can’t make drinkable water from seawater. This compact, hand-powered emergency desalinator can.
Uses the same reverse osmosis membrane as those in shipboard desalinators. A patented Energy Recovery System takes advantage of stored energy in the high-pressure reject water that is typically wasted. The pressurized reject water is recirculated to the back side of the piston to aid the next stroke, resulting in less work to achieve fresh water.
This unit is designed to be as light and compact as possible. Its nominal 30oz (890ml) per hour output is intended for survival situations only. For routine use, select a large, high-capacity desalinator.
