Hollow ultrafiltration membrane is a hollow fiber by the ultrafiltration membrane, which is ultrafiltration technology in the most mature and advanced technology.
Hollow fiber outer diameter is 0.5 to 2.0 mm, while inner diameter is 0.3 to 1.4 mm. Hollow fiber tube wall covered with microporous. The pore size is expressed in terms of the molecular weight of the substance that can be retained, and the molecular weight can be several thousand to several hundred thousand. Raw water in the hollow fiber outside or cavity pressure flow, respectively, constitute the external pressure and internal pressure. Ultrafiltration is a dynamic filtration process, the retained material can be excluded with the concentration of small, not to block the membrane surface, long-term continuous operation. Hollow ultrafiltration membrane experimental equipment is a multi-functional hollow film performance testing, water treatment and material separation equipment. It is suitable for different specifications of the hollow membrane module performance testing. It includes water flux, rejection rate and other performance parameters. At the same time, it also applies to water treatment, a small amount of material filtration and teaching demonstration purposes.
