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 have the following properties.

  1. Used together with organic flocculants.
  2. Used for the 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 aluminum oxide and ferric oxide.

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