Industrial Reverse Osmosis S-200 Antiscalant

Industrial Reverse Osmosis S-200 AntiscalantAXEON S-200 Antiscalant is a highly effective antiscalant, specially formulated for feedwater with the highest levels of metal oxides, silica and scale-forming minerals. It is effective over a wide range of concentrations, and does not flocculate dissolved polymers such as residual coagulants, iron or aluminum-rich silica. Use of this product is recommended for reducing the operating and capital costs of reverse osmosis (RO), nanofiltration (NF) and ultrafiltration (UF) systems. It inhibits polymerization of reactive silica, and disperses colloidal (non-reactive) silica.


  1. Effective in retarding polymerization and precipitation of silica
  2. Effectively controls inorganic scales over a large concentration range
  3. Certified under ANSI/NSF Standard 60 for drinking water production
  4. Compatible with major manufacturer’s RO, NF, and UF membranes
  5. Does not flocculate dissolved iron/aluminum oxide/silicate complexes
  6. May be used diluted or undiluted
  7. Effective in feedwaters with pH range 5.0 – 10.0
  8. Particularly effective for controlling coagulation of colloidal silica by aluminum, iron and heavy metal salts.


Appearance Clear, colorless pH 1.5 ± 0.8
Specific Gravity 1.08 ± 0.05 Packaging 5 gallons, 55 gallons

Dosing Recommendations

AXEON S-200 Antiscalant should be injected into the feedstream prior to the static mixter and cartridge filter. Effective pH range is 5 - 10. If frozen, may be thawed and mixed before use. Stability is excellent, but best used within 12 months.

In the useful dosage range of 1 - 50 ppm, S-200 controls of a wide range of inorganic scales along with reactive and nonreactive silica at high levels. By monitoring the concentrate stream and trend charts, optimal dosage can be achieved for the control of silica gels and scales, which form chemically linked foulants prone to flocculation with organic materials.
