R O Antiscalant Good Chemistry

An antiscalant is a pretreatment that gets injected into the feedwater that flows through the RO membrane, preventing the membrane from scaling. RO membrane scaling occurs when particles accumulate on a membrane, causing the membrane's pores to plug.Antiscalants adsorb on the nuclei of calcium solids and inhibit the crystal growth process. Activation energy of nucleation increased linearly with antiscalant dosage, but it decreased as the regime changed from homogeneous to heterogeneous nucleation.
