Membrane separation technology develops rapidly and ceramic nanofiltration membranes have broad application prospects

Nanofiltration membrane refers to a functional semipermeable membrane with a pore size above 1 nm that allows solvent molecules or certain low molecular weight solutes or low-priced ions to pass through. Nanofiltration membranes are usually divided into two categories: inorganic ceramic nanofiltration membranes and organic rolled nanofiltration membranes. Inorganic ceramic nanofiltration membrane, also known as…
