Product Description

AXEON's S-200 Antiscalant is a highly effective and specially formulated for feedwater with even the highest levels of metal oxides, silica, and scale-forming minerals. It is effective over a wide range of contaminant 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.

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

Appearance: Clear colorless liquid
Specific Gravity: 1.08 ± 0.05
pH: 1.5 ± 0.8

AXEON S-200 Antiscalant should be injected into the feedstream prior to the static mixer and cartridge filter. 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 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.

S-200 is Made in the USA.
