Hybrid membrane water filters



A major challenge to industry is to develop the next generation of energy efficient membranes. Most reverse osmosis membranes provide excellent salt exclusion with high permeation rates but this is at the expense of energy efficiency and high overall operation costs. Mimicking nature’s own water purification method, highly selective protein channels have been identified as a promising new alternative. The process has a low energy requirement however, further development of these organic membranes has been hindered by low yields and the high cost of making the recombinant proteins.


Produce a functional bilayer aquaporin membrane with significant water purification ability.


The project was successful in being able to produce large amounts of the aquaporin protein and developing a device that enables the a lipid bilayer to be bound to the aquaporin membrane.

Future Directions

Source additional funding to continue the development of the membrane.
