Interesting question is raised because that result that what I have got. Interesting, in one side it is known that the coating of TiO2 has caused higher affinity of membrane surface. In my opinion higher affinity, more or less, means higher permeability, higher chance that more water passes the pore of membrane. But my experiment shows the opposite. I just did a simple permeability though, but I think despite of its simplicity, it offers a very powerful tool to gain some insight about what is going on after coating in terms of its ability to allow water pass through the membrane. This post is dedicated to find out is it really true that the coating of TiO2 affect the pore size of membrane surface and make it denser.
I do not care if this post will contain only a couple hundred words. I just found an interesting definition of cake formation on the membrane surface. As you probably aware, this cake formation along with pore blockage, concentration polarization have caused fouling, sort of clogging in conventional filter, which increase negative value of membrane … Read more
