Main Uses of Microfiltration

Application areas

Examples of uses

Chemical industry

Filtration and clarification of various chemicals such as water, solvents, acids, and alkalis; separation of emulsified oil and water; emulsion filtration; filtration of high-viscosity polymer spinning solutions; filtration of impurities in coatings.

Petroleum, Machinery

Filtration and clarification of various oil products, such as fuel oil, lubricating oil, and cutting oil; separation of fermentation products and microbial cells; and oil-water separation.

Biochemical Engineering

Remove contaminating microorganisms during fermentation. This includes cell concentration and separation, and removal of mycoplasma-like structures.

Electronics Industry

Manufacturing of ultrapure water; refining and filtration of various reagents and gases in semiconductor manufacturing; air purification for clean rooms; refining of reagents and chemicals used in optical disc manufacturing.

Medical care, pharmaceuticals

Manufacturing of pyrogen-free purified water; sterilization of infusions, injections, and preparations; filtration and sterilization of blood filtration, plasma separation, serum, tissue culture, and other biological agents; clarification and sterilization filtration of active pharmaceutical ingredients, intermediates, and chemical raw materials.

Food Industry

Removal of yeast and mold from alcoholic beverages, beer, and carbonated drinks; clarification and filtration of sugar solutions; clarification and sterilization filtration of fruit juices and fruit wines.

Water treatment

Removal of suspended solids, microparticles and bacteria from water.
