8114 Antiscalant

INDION 8114 is an aqueous anionic polyelectrolyte solution for use in reverse osmosis (RO) applications. It inhibits the formation and growth of alkaline earth carbonate and sulfate scales. INDION 8114 also disperses suspended solids and colloids.

   Corrosivity

INDION 8114 is supplied at pH 4.3 to 5.3 and therefore does not require corrosive labeling or placards. Based on test results using the NACE Standard TM-O1-69(76) test procedure, INDION 8114 is not considered corrosive.

  Aquatic Toxicity

Aquatic toxicity testing indicates that INDION 8111 is relatively non-toxic to rainbow trout, daphnia, algae, inland silverside and mysid shrimp. Test results are available on specific request.
Packaging

INDION 8114 is available in packing of 5 kgs, 30 kgs and 200 kgs respectively.

Dosing

Typical dosage of INDION 8114 for controlling scale formation and minimising fouling in RO systems ranges from 5 to 20 ppm. A dosage projection is required for each system to determine the proper dosage. A complete water analysis is required and a filter analysis is recommended as a basis for accurate dosage projection.

  
Features   Benefits
  • Excellent dispersant of suspended solids and colloids
    		•
  • Maintains suspended solids and colloids in suspension     until rejection, thus minimising fouling
    		•
  • Excellent stabilizer of metal ions
    		•
  • Keeps metal (aluminium, iron, manganese) ions in     solution so they do not contribute to membrane fouling
    		•
  • Threshold inhibitor of alkaiine earth scales
    		•
  • Minimises or eliminates acid feed for scale control.     Inhibits the precipitation of:
        - CaCO3 at an LSI (or S & DSI ) up to +2.6
        - CaSO4, up to 1.8 times supersaturation
    		•
  • Crystal distorter
    		•
  • Modifies the crystalline structure of scale-forming     minerals such that they do not adhere well to     membrane and equipment surfaces, thus improving     system efficiency
    		•
  • Effective at low dosages
    		•
  • Cost-effective
    		•
  • NSF approved
    		•
  • Acceptable for use in potable water application
    		•
  • Water soluble
    		•
  • Can be injected as neat product or diluted as required
    		•
  • Contains no phosphorus
    		•
  • Complies with stringent effluent discharge requirements     for phosphorus
    		•
  • Hydrolytically, thermally, biologically stable
    		•
  • Retains activity during storage and use
    		•
  • Consistent product quality
    		•
  • Ensures predictable performance
