Membrane for Selective Removal of Ammonium Ions from Water

Eltron Research, Inc.

Boulder, CO

The firm has developed an ammonium-ion selective membrane to be used in a flowing electro dialysis cell configuration for the removal of low levels of ammonium from aqueous effluent streams.

• The firm's phase III plans are to form a separate jointly owned company between Eltron and an investment group for the fabrication and marketing of modular electrodialysis stack technology.

• There are over 1000 elctro dialysis plants installed world wide with the ability to treat 1000 cubic meters of water a day.
• A brief listing of sectors that could benefit from electrode ionization system are listed below.
  • Fish Farms - (Breeding tanks)
  • Animal Husbandry - (ground water run-off)
  • Waste Water Treatment Plants
  • Industrial/Commercial Outlets - (Hotels, Hospitals, and others)
• The firm has received six patents in relation to this technology.

• The firm is a small high technology company dedicated to performing basic and applied research in materials, environmental and catalyst technologies.
• The described technology will further enhance the firm's strategic position in water purification.
• The firm's goal is to be compatible with anticipated NASA needs for ammonium ion removal from space station waste water.
