- Abstract
- High concentrations of heavy metal and nitrate nitrogen concentrations cause severe problems in groundwater system all over the world. Especially, arsenic, lead and manganese are the most common heavy metals troubled in groundwater in Korea (Kim et al., 2015). Membrane separation technologies such as electrodialysis (ED) are increasingly being utilized due to its superior removal of dissolved contaminants (Jung et al., 2011; Mendoza et al., 2015; Ortiz et al., 2006). In this study, removal of heavy metals and nitrate nitrogen by an ED system was evaluated with the polluted groundwater in a rural area. Effects of different valance on separation during ED are also discussed.
