INDION 8115 Antiscalant for RO Membrane

INDION 8115 Antiscalant and RO Filtration Chemicals are excellent for reverse osmosis, nano filtration and electro dialysis reversal systems. It is highly effective in inhibiting the formation and growth of calcium phosphate, calcium carbonate, calcium/strontium/barium sulphate scales.

  • Certified to ANSI/NSF Standard 60 for the production of potable water by RO/NF/EDR
  • Highly effective across a broad spectrum of waters
  • Minimises scaling and reduces the frequency of membrane cleaning
  • Will reduce and usually replace the need for acid addition
  • Excellent threshold inhibitor and crystal distorter of alkaline earth metals & silica scales
  • Effective at low dosages
  • Compatible with most membrane types
  • Maintains colloids and metal ions in suspension until rejection thus minimising fouling


INDION 8115  RO Filtration Chemicals minimizes or eliminates acid feed for scale control, also disperses suspended solids and colloids thus improving system efficiency.
