Abstract
|
|
|
A laboratory experiment was performed to investigate the nitrate removal from groundwater using Iron chloride(Ⅲ) coated activated carbon (ICCAC). The breakthrough profiles of two ionic species, such as nitrate and sulfate showed that nitrate was selectively exchanged with chloride in ICCAC. The FeCl₃-coated activated carbon produced about 26 BV (Bed volume) of throughout when treating groundwater containing about 25 mg/l of NO₃-N. The regeneration of ICCAC with 1M KCl was effective at a flow rate of 4 BV/hr. The ion exchange technology seems to be suitable technology
for the treatment of small volumes of groundwater polluted by nitrate.
