IR-150 RO Antiscalant and Dispersant


IR-150 is a high-effective scale inhibitor. It is suitable for reverse osmose (RO), nanofiltration (NF) and ultrafiltration (UF) system. IR-150 can inhibit the scale deposit on the membrane surface. And also improve water quality. Lower operation expanse. IR-150 RO antiscalant and dispersant has the following properties.

  1. Used together with organic flocculants.
  2. Used for the 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.
  8. Good resistance to aluminum oxide and ferric oxide.

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