Desalination in Mining. With improvements in technology, desalination is becoming more viable both to provide source water and to treat process water Water access is a problem that must be overcome when starting or enlarging any mining project, and a lack of sufficient water in arid regions can be a deal-killer. Another water problem associated ...

Treatment of Ammonia-Nitrogen Wastewater by Electrodialysis
Treatment of Ammonia-Nitrogen Wastewater by Electrodialysis

The ammonia-nitrogen ,wastewater, was purified by using ,electrodialysis, (ED) device in this paper. The NH4Cl solution was used as the artificial ammonia-nitrogen ,wastewater,. Various unsteady factors in the experiment may cause the concentration polarization phenomenon, which may have negative effect on ED cell performance and its lifetime. The limiting voltage was confirmed as 12V in this study.
