Small-scale desalination approach to a big water problem
A research project recently undertaken at the Massachusetts Institute of Technology has revealed a new mechanism for desalination/purification of water, employing a microfluidic channel-network system, which could lead to the development of small and portable units. The authors have started to build a prototype device in the laboratory in order to demonstrate the necessary scale-up…

Desalination using forward osmosis with nanofiltration membranes
Forward osmosis (FO) is an emerging membrane technology, often used for desalination. Like reverse osmosis (RO), FO uses a semi-permeable membrane to separate water from dissolved solutes. The semi-permeable membrane acts as a barrier that allows water to pass through while blocking salts. Generally, any dense, non-porous, selectively permeable material can be used as a…

Depth Exposed Membrane for Water Extraction (DEMWAX™)
DXV Water Technologies has designed a novel membrane system that uses natural pressure, a very low recovery rate and gravity flow of feedwater past the membrane surface, resulting in an elegant, efficient system. Since the invention of the reverse-osmosis (RO) membrane researchers have tried to harness natural water-pressure, but past attempts mimic onshore processes with…
