The first part of this animation compares the transmembrane pressure (TMP) between a standard filter and a liquid gated membrane filter (depicted by pressure gauge in bottom right corner). The second part of the animation shows the tendency of each system to clog up due to fouling. The liquid gated membrane filter results in a lower TMP, which increases energy efficiency and reduces fouling, leading to lower maintenance cost and reduced energy consumption. The liquid gated membrane technology also enables multiphase separation and is compatible with standard filtration materials.
