Cleaning method of membrane

 

Functional nano ceramic flat film

Compared with traditional separation media, flat Ceramic membrane has the following advantages:

 

 

Long service life

● Under normal conditions, the service life can reach over 20 years.

High operating flux

● Under MBR conditions, the stable operating flux is higher than 30LMH.

Strong pollution resistance

● Strong anti pollution ability and good membrane regeneration performance.
● Through physical and chemical cleaning, high throughput recovery performance can be maintained for a long time.
● It can be combined with oxidants in the process to control membrane fouling online.

Easy to install and maintain

● Modular structure, convenient system installation and maintenance.
● The preservation and transportation of membranes do not require special preservation solutions.
● High degree of automation, online drug washing does not require manual operation.

Excellent physical and chemical performance

● Good chemical stability, high mechanical strength, acid alkali resistance, and corrosion resistance.
● Uniform pore size distribution and high filtration accuracy.
● Good hydrophilicity.
