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 ...

Well, as I have written several ideas in a very old posts, such as UF fractionation, TiO2 coating, photocatalysis effect to molecular weight distribution including gel filtration chromatography, now I want to summarize what I have done and brief result.

Well known as GFC, this is usually used to fractionate protein. It is based on molecular size, when larger particles will eluete first, followed by smaller molecule. In my experiment, I will employ this to fractionate humic substance. There are several points from which the method in using this GFC. ...

I have mentioned several information on my post about the effect of photocatalysis process to particle size distribution. Now in this post, I would like to a little bit further explain it more as I am really courious about this.

In this post, I would like to focus the effect of photocatalysis, in this case represented by Titanium dioxide and UV irradiation for organic particle distribution, which is natural organic matter, represented by Dissolved Organic Carbon, humical acid. I would like to know which organic particle size in responsible for ...
