Development of New Filter with Surface Modified MWCNTs

Abstract

In the development of membrane technologies, it needs a better understanding of the material characteristics and its mechanism for the improved membrane systems. This study focuses on the low energy consumption and time-saving system in which several membrane filters are coated by ultrasonic using Multi-Walled Carbon Nano Tube (MWCNT) solutions. The MWCNTs were modified by chemical oxidation and mechanical treatment to improve membrane performance. The morphological and structural analysis was carried out by using the transmission electron microscope (TEM) and raman spectroscopy. Dispersion characteristics of the prepared fluids were examined by UV/Vis/NIR spectrophotometer at operating wavelengths range from 250 to 900 nm. The particle size of the filtrate was investigated by particle size analyzer using incoming samples with a consistent size. In these results, it was confirmed that the mechanically treated filter was more effective than other filters by chemical methods. It is expected that any other membrane filter system can be applied.
