IR-191 RO Antiscalant and Dispersant


IR-191 is mainly used in the RO membrane system. It can be used as an antiscalant and anti-choking agent in high saltwater and drinking water. This RO antiscalant and dispersant have the following properties.

  1. Used in many water quality systems, good scale inhibition ability.
  2. Lower scale deposit and reduce RO pipeline cleaning frequency.
  3. Reduce or replace the acid fill treatment.
  4. Good economic effect.
  5. Suitable for all RO pipeline types and as an effective ferrium insulator.
  6. Stable and effective than Calgon (SHMP).
  7. High water flux density for the RO pipeline.

SolubilitySoluble well in any ratio


IR-191 should be added before the static mixer or cylindric filter for the best effect. A dosage of 1~4 mg/L is expected. IR-191 can be diluted by RO liquid or by deionized water.

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