IR-200 RO Antiscalant and Dispersant


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

  1. Used together with organic flocculants.
  2. Used for a drinking water system.
  3. Inhibit scale formation of calcium carbonate, calcium sulfate, barium sulfate, and strontium sulfate, and no scale is formed even when the 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.
