Liquid Membranes (LM)

removal/recovery of metals in liquid effluents, separation of gases with similar properties, treatment of residual streams.

LM is recognized as an effective method of selective separation. The technology consists of a liquid phase that separates two immiscible fluid phases, allowing selective transport from one phase to another. The driving force that governs the transport of matter in this process is the chemical potential gradient, which normally results in a difference in the concentrations between the two phases (feed and re-extractor).
