Fouling and chemical stability study on SiC-Al2O3 ultrafiltration membrane for sodium alginate filtration under constant flux crossflow mode

Trials of surface modifications using low pressure chemical vapor deposition (LPCVD) has successfully decreased the high temperature needed for the fabrication of SiC membrane from 2000°C to below 900 °C. With this great success on the reduction of the energy con-sumption, however, further studies on the chemical stability and the fouling...

Quantifying defects in ceramic tight ultra- and nanofiltration membranes and investigating their robustness

One of the perceived benefits of ceramic membranes is their robustness, which makes them suitable for treating high organic load waste streams. In particular, ceramic tight ultrafiltration (tUF) and nanofiltration (NF) form an important barrier against small colloids and organic molecules. In order to achieve this barrier, the quality of the...
