• Nasa Tech Briefs - Electrodialysi s To Remove Ammonium Ions From Wastewater: Electrodialysi s has been shown to be an effective means for removing ammonium ions from wastewater without use of consumable chemicals and without adding other substances to the treated water. It should be possible to apply this treatment principle to wastewater streams to be recycled in life-support systems for spacecraft and other closed habitats. Effluents from some industrial processes that generate high concentration of ammonium ions may also be treatable by this principle. In electrodialysi s an electric potential is applied across a membrane that is selectively permeable by the ions of interest ? in this case, ammonium (NH4+). Typically, a membrane suitable for this purpose comprises a polymer matrix, within which ionophores are immobilized. Membranes based on perfluorosulfo nic acid and membranes in which nonactin serves as the ionophore have been found to function efficiently as selective transporters of ammonium ions from effluent to concentrated-w aste stream.
