Technical details
Producer: Manta Ventures (USA)

Imagine that you´ve had to abandon ship and don´t know how long you´ll have to float around in a life raft waiting to be rescued. It´s hot and there´s not much fresh water available. How are you going to survive in your life raft?
Now imagine being able to convert sea water into a life giving drink without having to wear yourself out pumping a mechanical reverse osmosis seawater filter for hours in the scorching sun. The SeaPack passive emergency desalination system does just that. Without having to hand pump or use electrical power the SeaPack removes pure water from the sea and transforms it into a drink that is high in calories to provide you energy. Perfect for surviving in your life raft.
Small enough to fit in a kayak, life raft canister or in the emergency ditch bag on your boat, the SeaPack is made to save your life when all else fails.
The SeaPack employs a proprietary membrane filter that is hydrophilic (attracts water), allows water to pass through, yet blocks very small contaminants due to the tight construction of the membrane.
Developed in concert with the US Department of Defense, SeaPack filters have undergone extensive testing in independent laboratories and by the U.S. military. The nominal pore size of the SeaPack forward osmosis membrane is 3-5 angstroms. The size of bacteria range from 2,000 to over 500,000 angstroms. The smallest viruses are 50 to 1,000 angstroms. To put this in perspective, if SeaPack´s membrane pore is compared to the size of a dime then the smallest bacteria would be larger than a two-car garage.
With over fifteen years of research, scientists have developed the world´s first commercially viable forward osmosis membrane for emergency desalination. This membrane has been used by NASA, the US Department of Defense, branches of the US military and is now available to the public for use in emergency desalination situations. www.sea-pack.com
