mikrosuodatusta

Mikrosuodatusta, also known as microfiltration, is a physical filtration process used to separate suspended solids from liquids or gases. It operates by forcing the fluid through a porous membrane with pore sizes typically ranging from 0.1 to 10 micrometers. This pore size is crucial as it allows water and dissolved substances to pass through while retaining larger particles such as bacteria, protozoa, sediment, and colloids.

The process is driven by a pressure difference across the membrane, which can be achieved through various methods including gravity, centrifugal force, or applied pressure. Mikrosuodatusta is a cost-effective and energy-efficient separation technique, often employed as a pre-treatment step before more advanced filtration methods like ultrafiltration or reverse osmosis. Its applications are widespread, including water purification for drinking and industrial use, clarification of beverages, and in the pharmaceutical and biotechnology industries for sterilizing solutions and separating cells. The membranes used are typically made from materials like polymers (e.g., polysulfone, polyvinylidene fluoride) or ceramics, chosen for their chemical resistance and durability. The effectiveness of mikrosuodatusta depends on factors such as pore size, membrane material, operating pressure, and the characteristics of the feed stream.
