Reclaiming means to produce a new supply by combining or breaking down by-products of other processes [1]. National Aeronautics and Space Administration or NASA, spelled NASA life support system engineers refer to the recycling of water and air as “closing the loop.” The by-products of human metabolism, carbon dioxide (lethal in high concentrations) and water vapor, present a challenge in terms of removing these from the [1].
