Rotating dynamic membrane separation technology adopts the form of "membrane movement", that is, during the separation process, the disk-shaped membrane rotates at a high speed, without requiring a large amount of material to circulate. A rotating disk is used to drive the fluid to rotate, and the viscosity of the fluid itself drives it. At the same time, the rotation will generate centrifugal force to cause the fluid to flow radially, driving the fluid to enter and exit the device, so that high membrane surface shear force can be generated even at a very low inlet flow rate. Minimize the impact of membrane fouling and concentration polarization and improve membrane flux. This technology is different from traditional dynamic membrane separation technology. It can minimize the driving force of the process, rely on the rotation of the system itself to achieve membrane regeneration, ensure filtration and separation accuracy and processing capacity, and achieve continuous and efficient operation of the process. Based on rotating dynamic membrane filtration technology, continuous, efficient and dynamic operation of membrane separation technology in the fields of liquid purification, wastewater treatment, liquid-solid separation, etc. can be realized, and membrane separation technology can be better applied in practical industries and energy conservation and environmental protection industries, and drive the progress of related industries.
