Liquid Gated Membranes (LGM) mimic nature’s use of liquid-filled pores to control movement of liquids, gases and particles. LGMs operate at low trans-membrane pressures (TMP), resist fouling, minimize TMP build-up, and lower maintenance and energy costs. LGMs enable separation of multi-phase mixtures and are compatible with common filter materials.

Value Proposition: LGMs offer three significant benefits for industrial filtration processes.
1. Lowers energy and maintenance costs. LGMs operate at lower trans-membrane pressures (TMP) than conventional filters and show minimal TMP build-up caused by pore clogging, scaling or bio-fouling. LGMs are coated with strongly wetting liquids selected so that their affinity for the membrane material is stronger than that of the filtrate. This ensures that the filtrate will flow through liquid-lined pores without contacting the coated membrane, preventing fouling both inside and around each pore. This performance can lead to longer filter duty cycles and significant energy savings over time.
2. Tunable multiphase separations. LGMs provide a stable and robust mechanism for controlling gas and liquid transport. For a given membrane material, pore size and feed, a compatible pore filling/lining liquid can be selected to differentially control separation of multiphase mixtures
3. Material compatibility. All commonly used membrane materials can be used in the design of LGMs for a wide range of industrial filtration applications. This allows rapid scale-up of the technology and ensures that the cost of LGMs can be competitive with currently marketed filter products.
