Investigation of Saline and Brackish Waters Desalination by Carbon Aerogel Technology

The Capacitive Deionization Technology (CDI) with carbon aerogel is a new process to remove salt from saline and brackish waters. Carbon aerogel is type of organic carbon, which your unique porous structure is suitable for desalinating. Low potential for clogging, production low wastewater, electrostatic regeneration aerogels and consequently no need to be acid, including the benefits of this technology. In this regard, the first polymerization resorcinol compounds and formaldehyde in the air pressure and the pyrolysis compounds obtained, Will attempt to create carbon aerogel pages. By manufacturing device in the pilotscale, the effect of different parameters includes the input of NaCl concentration, electric current, flow, distance between electrodes and pH, on NaCl absorption by aerogel carbon electrodes was investigated. Absorption rate by increasing flow and NaCl concentration in the input flow were increases more and increasing the distance between the electrodes, Flow and pH decrease the amount of absorption rate. Results in optimal conditions, Shows the absorption rate 1.43×10-4 moles of NaCl Per gram of was by carbon aerogel that suggests this method is appropriate and cost-effectiveness.
