molecular filtration (rus. молекулярная фильтрация otherwise мембранная фильтрация; ультрафильтрация) — molecular sieve effect based separation of substances using membranes with size of pores equivalent to the size of molecules contained in such substances.


The concept of molecular filtration involves several membrane separation processes, such as reverse osmosis, nanofiltration and ultrafiltration, and applies to membranes with pores sized smaller than 100 nm.
