[Specifics of sorption after purification of permeates produced by nanofiltration of washing water in pressurized modules].
Data on the quality of sorption afterpurification of permeates produced by nanofiltration of washing water in the ECOPSY-95 project are presented. Washing water contained essentially different detergents. Nanofiltration was performed with reeled composite membrane filters (OPMN-K). Nanofiltrated permeates were further treated with sorption techniques. The investigation confirmed the possibility get a filtrate complying with the washing water requirements. It was demonstrated that afterpurification of nanofiltered permeates by sorption improves the quality of regenerated water and also extends useful life of expandable sorption materials as compared to washing water that was not subjected to nanofiltration. Combination of nanofitration and sorption can be favorable to decrease the size of filter cartridges by 30-50%.
