Features of planted membrane filters

This post was last edited by sunjl1981 on 2013-1-6 20:06 Let’s discuss the characteristics of the planted membrane filter. Our company uses the planted membrane filter, but the overall effect is not very good, especially the membrane is easily blocked and the backwashing is not thorough. .Note ← ) # ← , .
What the poster is talking about is that the outside of the filter tube is a planted membrane filter wrapped with filter cloth. We have this kind of process, which is divided into two types: coarse filtration and fine filtration. The coarse filtration is pre-coated with fly ash. The effect we use is not bad. If the MgoH2 content in the coarse filtration is high and the pressure rises quickly, it can only filter CaCO3. The effect is OK, but the effect cannot be compared with Kai Membrane and Gore: loveliness:
Yes, the filter element is wrapped with filter cloth and is often easily clogged.
The main reason is that they are afraid of colloids, which can easily gather other impurities and form an impurity layer on the membrane. :lol Magnesium hydroxide and ferric hydroxide are colloids that can easily gather other impurities. The content of colloidal impurities must be controlled. Please tell me if I’m wrong!
After about a month of use, you can use 10--15% hydrochloric acid to clean it.
