IR-150 RO Antiscalant and Dispersant


IR-150 is a high-effective scale inhibitor. It is suitable for the reverse to osmose (RO), nanofiltration (NF), and ultrafiltration (UF) systems. IR-150 can inhibit the scale deposit on the membrane surface, improve water quality, and lower the operation expanse.


AppearanceAmber transparent liquid
pH Value (1% water solution)2.85±1.0
Density (20℃), g/cm31.10 Min.


IR-150 has the following applications.

  1. Used together with organic flocculants.
  2. Used for drinking water system.
  3. Inhibit scale formation of calcium carbonate, calcium sulfate, barium sulfate, and strontium sulfate. 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.
  8. Good resistance to alumina oxide and ferric oxide.


For best effectiveness, IR-150 should be added before a static mixer or cylindric filter, the dosage of 3~6 mg/L is expected, and it can be diluted by RO liquid or deionized water.

Notes: extra or insufficient dosage will harm the RO membrane.
