With increasing requirement worldwide, the advent of desalination technology using carbon nanotubes to address energy issues seems a practical option. This project intends to provide an in-depth insight on the application of MWCNTs to heighten the performance of seawater desalination in a universal manner. The mechanical and chemical properties of this material to facilitate excellent flux of water transport and salt rejection are outlined. The raw MWCNTs are modified accordingly and subsequent tests are then carried out to study the characteristic changes of MWCNTs. With use of FTC apparatus, desalination trials are then carried out for various samples and concentrations that help in optimization of desalination technique using MWCNTs. Cost effective measures are then analyzed and are modified accordingly. By measuring the TDS before and after we show the efficiency of the desalination process with each sample and concentration. The current hurdles and future challenges related to this technology are also addressed.
