Membraneerottimet

Membraneerottimet, often translated as membrane filters, are porous materials designed to separate substances based on particle size. They are characterized by their pore size, which can range from very small (nanometers) to relatively large (micrometers). This precise pore structure allows for selective passage of molecules and particles.

The manufacturing process of membrane filters involves various techniques, including phase inversion, track-etching, and stretching. The choice of material, such as polymers like polysulfone, polyvinylidene fluoride (PVDF), or cellulose esters, is crucial and depends on the intended application and the chemical compatibility required.

Membrane filters find widespread use across numerous industries. In water purification, they are essential for removing bacteria, viruses, and other contaminants. The pharmaceutical industry employs them for sterile filtration of drugs and biological solutions. They are also utilized in the food and beverage sector for clarification and microbial control, as well as in laboratory settings for a variety of analytical and preparative procedures. The efficiency and specificity of membrane filtration make it a vital technology for achieving high purity and safety standards in many applications.
