The Aquaporin company is focusing on mimicking the ability of lipid bilayers in biological cells to transport water back and forth across membranes by way of membrane channel proteins called aquaporins. Aquaporins can facilitate this transport while excluding any particles or ions that are not water. The Aquaporin company’s goal is to create a new class of water filtration membranes that use aquaporins as cornerstones in water filtering devices to be employed in industrial and household water filtration and purification.
Most separation membranes in use today consist of dense polymeric films where the surface properties are controlled by advanced chemical engineering. This has resulted in a vast array of separation membranes specifically designed for certain applications. However, almost all of these synthetic membranes are made of polymer sheets consisting of micron- to nanometer-sized holes and require the use of pressure to push water through the membranes.
Aquaporins are selective membrane channel proteins found in the lipid bilayer of living cells that work to transport water across the cell membrane. Aquaporins accomplish this task while excluding any unwanted ions or other polar molecules, making them a perfect model for the formulation of low-energy water filtration systems.
Many current water filtration and purification techniques are inefficient and energy-intensive.Edit Summary
