Reverse Osmosis Membrane Antiscalant
Specifically formulated polymeric antiscalant for reverse osmosis (RO) and nanofiltration (NF) membranes, preventing calcium carbonate, calcium sulfate, silica, barium sulfate, and strontium sulfate scaling in concentrate streams. Enables higher system recovery rates while extending membrane cleaning intervals. Compatible with all commercial thin-film composite membranes.
