摘要

The integrated membrane process for clarification and concentration of sodium salt of vitamin C is projected as an emerging technology in operations where salts/ions recovery is the prime objective. This study presents a novel integrated microfiltration-reverse osmosis process. The study achieved a product recovery rate of 94.7% and an overall product retention of 91.40%. A significant contribution of cake layer and fouling resistance was observed indicating greater salt retention. The MF process effectively removed larger impurities, while the RO process concentrated the desired product. The average flux values for microfiltration and reverse osmosis unit were 14.13 and 7.19 L/m2 h, respectively. The results indicate that the integrated MF-RO system can significantly enhance the recovery of sodium ascorbyl phosphate, demonstrating its potential for practical applications in industries focused on salts and ions recovery. Good restoration of water permeability of the membrane for both MF-RO was observed after cleaning treatment.
