When the ultrafiltration membrane is clogged, what cleaning methods are there?

Date of release:2018-08-27 Author: Click:

During the operation of the ultrafiltration membrane, the fear is that the entire membrane is clogged due to too much or too much impurities. This is very undesired, but it is often encountered. These conditions are inevitable in some cases. So there needs to be a particularly good way to solve it, this is the issue of concern.


Ultrafiltration is a pressure-driven membrane separation process with a filtration accuracy in the range of 0.005-0.01 um. The main component of ultrafiltration technology is ultrafiltration membrane. After using for a period of time, the ultrafiltration membrane will deposit some separated substances and other impurities on the surface of the membrane, which will pollute and block the membrane. The effective cleaning of the membrane is An important means of extending the life of the membrane. Commonly used cleaning methods are chemical cleaning and physical cleaning.


Ultrafiltration membrane clear maintenance

How to clean and protect the ultrafiltration membrane? The ultrafiltration membrane has a pore size range of 0.01 micron or less. By applying a suitable pressure to one side of the membrane, solute molecules smaller than the pore size can be sieved to separate particles having a molecular weight greater than 500 Daltons (atomic mass units) and a particle size greater than 10 nm.



1. Raw water uses fungicides to kill bacteria and microorganisms and maintain proper residual chlorine.


2. Pre-filtration removes the solid particle suspension, and when the colloid content is high, it is pretreated by flocculation precipitation.


3, regular backwashing, rapid flushing, regular chemical flushing.


4, dynamic filtration, discharge concentrated water, recycling depends on the quality of raw water.


5. Slowly raise and lower pressure to prevent impact.


In fact, we think about the problem is very simple, why these impurities can be adsorbed on the ultrafiltration membrane, because the problem of internal liquid flow is flowing in the direction of the membrane, this result will inevitably occur, with this kind of thinking, it can be simple The solution is to reverse the operation of the ultrafiltration membrane, so that it can flow down the impurities in the membrane, which is very good and the time is very
