Ultrafiltration Membrane Elements

Spiral Wound Ultrafiltration Membrane

VUF Series ultrafiltration membrane is spiral wound polyether sulfone membrane element. It has the characteristics of high heat resistance and chemical stability, uniform pore size and high molecule cut off accuracy. The VUF series ultrafiltration membrane is welded by rotary welding process, which ensures very low fluid resistance and high durability of the membrane element.

Applications

VUF series ultrafiltration membrane can effectively remove proteins, viruses, macromolecular organics, pigments, polysaccharides and other macromolecular from water, and permeate inorganic salts, micromolecular pigments, monosaccharides and other micromolecular substances and water. It also can be used for separating different molecular weight materials to achieve the purpose of decolorization, purification and separation and concentration. VUF series ultrafiltration membranes are mainly used in the treatment of electronic ultrapure water, drinking water, municipal water and various industrial water, the pretreatment of RO system, and the separation and concentration of materials in biochemical, pharmaceutical and food industry.

The VUF series is mainly used for separation and concentration of specific material with molecular weight cut off (MWCO) at 4k, 6k, 8k, 10k, 20k, 67k Da. VUF series applies the feed channel spacer of 31, 46 and 90mil, and is favorably equipped with the fiberglass housing of sanitary-grade housing.
