Ultrafiltration membranes are a type of microporous filtration membrane with uniform pore sizes and a rated pore size range of less than 0.01 microns. When an appropriate pressure is applied to one side of the membrane, solute molecules smaller than the pore size can be screened out, thereby separating particles with a molecular weight greater than 500 Daltons (atomic mass units) and a particle size greater than 10 nanometers. Ultrafiltration membranes are one of the earlier developed high-molecular separation membranes, and ultrafiltration devices were industrialized in the 1960s. They can separate target products of different molecular weights, thus replacing traditional purification processes such as activated carbon decolorization, resin impurity removal, and crystallization extraction, achieving the purposes of decolorization, impurity removal, and product classification.
Wuhan Bona has established long-term and friendly cooperative relationships with numerous global suppliers of organic membrane elements. We have imported a large number of high-performance original organic membrane elements, membrane modules and organic membrane accessories. We offer a variety of materials and molecular weight cut-off spiral wound ultrafiltration membrane elements, which are compact in structure and have a reasonable surface area/volume ratio. By using different flow channel nets (13-120 mil), the width of the feed liquid flow channel can be changed to adapt to feed liquids of various viscosities. We can also select the appropriate ultrafiltration membrane for customers based on their process requirements, treatment systems and related technical requirements.
