Sep 29, 2021· This pH increase during desorption is problematic, especially when we operate at high water recoveries, resulting in high salt concentrations in the flow channel during desorption. These conditions, with high salt concentrations combined with high pH values, can lead to the precipitation of salts such as calcium carbonate (scaling) on membranes
