Industry Leading Performance

  • High selectivity monovalent ion exchange membranes (i.e. remove chlorides and leave in sulfates) that enable advanced separations previously impossible
  • High multivalent ion transference removes scaling ions for reduced fouling in downstream RO and concentration processes
  • Resilient in scaling and oily wastewaters, hydrocarbon tolerance C1–C10

  • Highly resistant to oxidizing agents (up to 1,000 ppm) including bleach

  • Stable over pH 0–12 and up to 60°C (140°F)

  • Smooth membrane surface minimizes fouling and scaling

  • Mechanically strong — ductile and tear resistant

Groundbreaking Selectivity

  • Effectively separate mono- and multi-valent ions with 98% monovalent ionic selectivity
  • Perform previously impossible chemical separations
  • 40% higher selectivity than conventional ion exchange membranes
