Unlike Ultrafiltration and Nanofiltration, which use membranes with smaller pore sizes, Microfiltration membranes have larger pore sizes typically ranging from 0.1 to 10 micrometers.

During microfiltration, the liquid to be treated, known as the feed stream, is passed through a porous membrane under pressure.

The membrane acts as a physical barrier, allowing only particles smaller than the pore size to pass through, while larger particles are retained on the membrane surface or within its pores. This separation mechanism is mainly based on size exclusion, as particles larger than the membrane pores cannot permeate through.

Overall, microfiltration provides an efficient and cost-effective solution for separating particles from liquids across a wide range of applications, contributing to the production of high-quality water and process fluids.
