System of using soft spberical particles to proceed membrane cleaning and its cleaning method

Abstract

A system and method for washing membrane by soft spherical particles and liquid flowing features that a washing liquid channel and a small particle circulator for releasing small particles are used to clean the surface of membrane, restoring the membrane permeability.

Description

technical field [0001] The present invention relates to a membrane cleaning system and its cleaning method. Furthermore, it relates to a membrane cleaning system and its cleaning method capable of bringing the following effects: soft spherical particles and feed liquid run synchronously, relying on the particles in the running process It rubs against the membrane and causes the disturbance of the liquid flow, completes the cleaning of the membrane surface and restores the membrane flux. Background technique [0002] Membrane separation technology has developed rapidly in the past 20 years and has been widely used in chemical, food, medicine, electronics and other industries. However, the membrane will be polluted during use, which will reduce the performance of the membrane. In severe cases, the value of membrane separation will lose its practical application value, thus limiting the application field of membrane separation technology. An effective cleaning method is an imp...

AI Technical Summary

Problems solved by technology

There are certain defects in the chemical cleaning method: for a system with complex components, it is relatively difficult to choose a cleaning agent, and at the same time, cleaning waste liquid will be generated, and its cleaning effect is also limited

But this cleaning method has the problem of low cleaning efficiency.

[0004] The cleaning effect of the above cleaning methods is limited by their own conditions, and cannot completely solve the problem of membrane fouling during the use of the membrane, especially in the treatment of viscous materials.
