These revolutionary forward osmosis water filtration products were originally developed in cooperation with the US Department of Defense for soldier hydration and are new to the UK from Fox's Online.  Funded by the Defense Advanced Research Projects Agency (DARPA), the goal of the original project was to develop a means by which a soldier could drink any water found on the ground, no matter how contaminated - this has obvious survival benefits for Sailors, those on Outdoor treks, and expedition leaders.  There were a number of water technologies involved in the project, but critical to meeting the goals of the research was the ability to work well with seawater, and muddy or turbid water. The manufacturer, HTI, has refined and improved its forward osmosis products and is now recognized as the leading authority on osmotic membranes and forward osmosis products. DARPA understood that forward osmosis was the only technology that had the potential to work unimpeded in thick, dirty water
