Express Method for Assessing the Efficiency of Antiscalants Used in Baromembrane Systems

Abstract

Membrane separation of solutions is inextricably connected with the phenomenon of concentration polarization. If the solution composition includes hardness salts, it involves the possible precipitation on the membrane surface. In practice, special antiscalant chemicals are used to prevent sediment formation in the process of membrane separation. The application of antiscalants is associated with the need of determining their optimal dosage for each specific entity subject to separation. In many cases, it requires long-term experiments. This paper proposes an express method for the selection of antiscalants and assessment of their efficiency.
