摘要：

In the sugar industry, ion-exchange resins have a problem with regeneration waste disposal since the regeneration effluent contains a high concentration of sodium chloride and colored organics. In the present work the recovery and recycling of waste brine previously used for decolorizing sugar liquor has been investigated using cost-effective organic spiral-wound nanofiltration membranes. A 74% reduction in salt consumption and an 89% reduction in water consumption were achieved in the batch configuration at VCF 9.
