Enhancement of Membrane Separation Performance

Surface modification of polymer membranes is required to adjust the properties of a base membrane polymer for various filtration applications (drinking and waste water treatment, seawater desalination, liquid/liquid separation). The zeta potential is sensitive to small changes in the surface chemistry and thus suitable for monitoring membrane performance. This application note demonstrates the real-time measurement of surface Zeta Potential using the SurPASS 3 system from Anton Paar.
