In this post I want to know about the flux recovery rate. From the book Basic Principles of Membrane Technology I found out the explanation about recovery rate. It define the ratio between qp and qr. Qp is permeate flow rate while Qr is feed stream flow rate. Before I ...

This post is dedicated to answer several questions raised why TiO2 being a popular photocatalyst and thus often being used for photocatalysis and photodegradation any unwanted compounds or chemicals including microorganism, organic particles.
I just found in a paper of Weimin Xi (2001), he stated that TiO2 is having considerable photocatalytic ...

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 ...

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 ...

Combine with microfiltration, ultrafiltration (UF) is a low pressure membrane. UF is usually used for potable water treatment, biological wastewater treatment and also for ultrapure water production. The latter is common method for metal or electronic industries. UF typically operates within 40-1000 kPa (5.8-145 psi) (0.4-10 bar) having molecular weight ...
