INDION 8211 RO Filtration Antiscalant

INDION 8211 Antiscalant is an excellent multi functional filtration chemical for use in reverse osmosis, nano filtration and electro dialysis reversal systems. It inhibits the formation and growth of silica, calcium carbonate, calcium sulphate, strontium sulphate, barium sulphate, calcium fluorides and metal oxides scales.

  • 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

Description

INDION 8211 RO Filtration Antiscalant minimizes or eliminates acid feed for scale control, also disperses metal ions and colloids thus improving RO system efficiency.
