영문 초록

A laboratory experiment was performed to investipate 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 throughput when treating groundwater which contained about 25mg/l of NO3-N. The regeneration of ICCAC with 1M KCl is possible 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.
