Antiscalant for RO Membrane
CAS Number: 37971-36-1
RO membrane antiscalants are specialty formulations designed to prevent the precipitation of calcium carbonate, calcium sulfate, barium sulfate, silica, and metal oxide scales on reverse osmosis and nanofiltration membrane surfaces. They extend membrane life, maintain high permeate flux, and allow operation at higher recovery ratios. These products are certified for use in drinking water RO systems.
