Abstract

Objectives and Background: The increasing demand for drinking water has led scientists to the use of saline waters, but existing DESALINATING processes are very expensive. CARBON AEROGEL is a type of organic aerogel that is suitable for desalination owing to its unique porous structure. Low potential of fouling and deposits, very low wastewater production, electrostatic regeneration of aerogels and, in turn, no need to acid consumption, and lower power consumption are some of this technology benefits.Materials and Method: In this experimental- analytical study, the purpose was survey of saline and brackish water desalination using CARBON AEROGEL technology and its comparison with electrolysis.The community studied was synthetic salt water samples, using of TDS and EC indicators. The minimum synthetic samples were 243. In this regard, after polymerization of Resorsinol and Formaldehyde compounds under ambient pressure conditions and then its pyrolysis, we fabricated plates of CARBON AEROGEL.Result: With manufacturing in the pilot-scale, the effect of different parameters, including input salt concentration, current, water flow, distance of between electrodes and pH, on NaCl sorption amount of CARBON AEROGEL electrodes were studied. Generally, adsorption amount increased with increasing of current and NaCl concentration and decreased with increasing of distance electrodes, flow and pH.Results: Fabricating reactor at pilot-scale, we studied the effect of different parameters, including input salt concentration, current, water flow, intra-distance of electrodes, and pH on the NaCl sorption using CARBON AEROGEL electrodes. Generally, adsorption capacity increased with increasing of current and NaCl concentration in the inlet flow, and it decreased with increasing intra-distance of electrodes, flow, and pH.Conclusion: Under the most optimal conditions, our results showed that the NaCl adsorption rate on CARBON AEROGEL electrodes was about 1.43´10-4 M NaCl per g of CARBON AEROGELs indicating its cost-effectiveness.
