Inorganic additives for membrane fouling reduction

Technology that dramatically improves the antifouling performance of membranes that are used for industrial processes, such as filtration. Membranes are pervasive in membrane bioreactors that are used for ultrafiltration applications such as water purification and wastewater treatment. The issue is that these membranes are prone to fouling. This technology is a method to dramatically improve the performance of these membranes.

By modifying the casting solution used to manufacture polymer membranes with a simple, low-cost dopants such as salt and clay, permeability can be increased by 100 – 400%, with a dramatic improvement in anti-fouling performance.
