Water Filtration

Most disaster and RV water filter systems involve forward osmosis, which can make potable water even from muddy water. Often used by the military in both war zones and areas of disaster relief, forward osmosis utilizes a semi-permeable membrane that separates water from dissolved solutes.  Pathogens and toxins can be rejected by the forward osmosis membrane. 

Investigation of further developing of this process using hydration bags is underway. These hydration bags sometimes have the capacity to separate water from such agents as glucose and fructose, and may eventually lead to the ability to recycle urine as safe drinking water for the benefit of soldiers or backpackers, as well as the recycling of seawater as potable drinking water.
