Novel Drinking Water Systems

Novel Drinking Water Systems

We target drinking water supplies, particularly for remote and undeveloped areas and for emergency provision due to natural disasters. Examples include gravity driven membrane devices for application in flood and earthquake areas, and batch forward osmosis for emergency drinking water. Forward osmosis is being studied as a low energy alternative for desalination, particularly the design of novel draw solutions which are inexpensive, generate high osmotic pressure, non-toxic and can be regenerated at low energy. We are also applying pre-coagulation behind a UF membrane to intensify the treatment of raw, upland waters.
