Molecular weight cut-off (MWCO) refers to the maximum molecular weight of solutes that can pass through a membrane, which is critical in membrane filtration processes. It determines the selectivity of a membrane, allowing certain molecules to permeate while retaining larger ones, impacting separation mechanisms and process parameters. Understanding MWCO is essential in applications such as water softening and contaminant removal, as it directly influences the efficiency of the filtration process.
