Stan1268, Report II:The objective of this part of the study was to develop a simple method tointroduce the zwitterions or other functional groups into surface membranes in order toaddress the deficiencies identified in Part I of this project: decrease irreversible fouling,most importantly for DNAN and under conditions of high ionic strength, enhancerejections and increase recovery of treated water. The selected surface modificationmethod is a one-step operation based on alkoxysilane polycondensation by sol-gelprocess
