Planning ahead: theses
Wednesday, March 14th, 2007Right, I am trying to list here what I am planning to do within short time: At the moment, I am cleaning my all membranes after TiO2-UV batch: 1 kD, 15 and 50 kD, two pieces for each.

TiO2 coating procedures
Tuesday, March 13th, 2007There are various methods available to coat TiO2 onto the surface of the membrane. I will explain briefly some of them, and the method I used. Ion assisted deposition This method was used for coating on super-hydrophobic porous teflon membrane. The author stated that the coating of TiO2 by the chemical wet ...
TiO2-UV batch for UF fractionation
Saturday, March 10th, 2007The result of my experiment employing TiO2-UV was not satisfying. In terms of flux, TiO2-UV membrane showed severe decline after 30, 60, and around 90 minutes. Not only that, the rejection of membrane coated by TiO2 under UV exposure was lower than naked membrane. This probably due to smaller ...
TiO2-UV performance
Monday, March 5th, 2007First stage of experiment has been accomplished. The result was not satisfying. I used 50, 15 and 1 kD. In terms of flux and accumulated flux, TiO2-UV displayed lower result compare to just naked membrane. Although for 50 kD and 15 kD initial flux were higher than naked membrane, but ...
Abstract for Scientific Paper
Saturday, March 3rd, 2007Yesterday I was requested to join Internation Symposium held in Taiwan. One of the requirement to join is to submit abstract before due date which is next week. While I am writing my own abstract, I think it is good idea to put something here about how to write abstract. ...
Complete the first task
Thursday, February 22nd, 2007So, basically what I am going to do is to complete first target within this month. I hope I can accomplish it ontime. It has already been posted before about the performance in terms of flux, rejection of several membrane pore size, 50 kD and 15 kD. Now, I will ...
Seems TiO2+UV do not have effect toward HA removal
Tuesday, February 20th, 2007I almost finished my current short term goal. I did some tests, using membrane 50 kD, 15 kD. For both, I used same comparison, one using TiO2 coating plus UV, the other one without them, just naked membrane. Seems that percentage removal of TOC between TiO2+UV membrane and just naked ...
