Hollow Fiber Membrane Filter uses a polysulfone membrane, which is characterized by excellent filtration performance and heat and chemical resistance. This helps to achieve high precision filtration,at 0.04, 0.1, 0.2, 0.45 and 0.8 μm.
Our membrane filtration technology is used in many different applications because of the commercialization of cartridge filters using hollow fiber membrane filters for polysulfone, which is compatible with severe conditions for separation and refinement, namely the efficient filtration of fluid containing 0.04 - 0.8 micrometer fine particles. This area is regarded as a boundary between precision filtration and ultrafiltration. This is an area of high precision filtration.
Hollow Fiber Membrane Filter has high porosity and allows for a large membrane area. Therefore it has a very high level of filtration capability. It also excels in heat and chemical resistance.
This products contributes to the above goals among the SDGs.
A filtration system can be designed with the use of Hollow Fiber Membrane Filters.
