How To Prevent Gypsum Scale | Engineer Live

May 18, 2020· If gypsum scale has already built up, perhaps due to using ineffective antiscalants or dosing inappropriately, removing it without damaging the membrane is challenging, but not impossible. This should be done as promptly as possible to prevent the scale itself causing irreversible damage to the membrane surface.
