TFC membranes (thin-film composite membranes)

TFC (thin-film composite) membranes are advanced materials used primarily in water filtration and desalination. They consist of a very thin, dense layer of specialized polymer that acts as a barrier to impurities, supported by a stronger, porous backing layer for durability. Water passes through the tiny pores in the membrane, leaving contaminants behind. The thin, selective layer allows high water permeability while blocking salts, bacteria, and other impurities, making TFC membranes efficient for producing clean drinking water or treating wastewater. Their design enhances performance, energy efficiency, and lifespan in filtration systems.
