IR-200 RO Antiscalant and Dispersant


IR-200 is a high-effective scale inhibitor, it is suitable for reverse osmose (RO), nanofiltration (NF) and ultrafiltration (UF) system. It can inhibit the scale deposit on the membrane surface, improve water quality, lower operation expanse. This product has the following

  1. Used together with organic flocculants.
  2. Used for a drinking water system.
  3. Inhibit scales formation of calcium carbonate, calcium sulfate, barium sulfate, and strontium sulfate, no scale is formed even when LSI value is 3.0.
  4. Used for almost all RO membranes.
  5. Maintain the surface of the RO membrane clean by dispersing particle blockage.
  6. Effective in pH 5-9.
  7. Used directly, or after dilution.

Good resistance to aluminum oxide and ferric oxide.
