dc.description.abstract | The paper presents some relevant aspects related to the influence of pollution matrix specific to the groundwater supplies, upon the treatment technologies applied in order to remove the inorganic nitrogen - based compounds (ammonium, nitrite, nitrate ions). The main association of ammonium (NH4+) with inorganic/organic pollutants in groundwater are, as follows: NH4+ and metallic ions (Mn Fe); NH4+ and sulphur derivatives (S2-, S2O32-, SO32-); NH4+ and nitrite/nitrate ions (NO2-/ NO3-); NH4+ and natural organic matter (NOM - THMs precursors) in the presence of bromide ion (Br-). Also, the concentration levels of nitrogen - based compounds and associated pollutants are very important in the selection of suitable treatment procedures, including the succession of treatment steps. The treatment technologies developed for NH4+ and NO3- ions removal from groundwater supplies have as specific steps: breakpoint chlorination (NH4+) or biological nitrification (NH4+) and denitrification (NO2-/ NO3-) processes. Among the main problems specific for the most applied technology at industrial level for NH4+ oxidizable pollutants removal (one step chlorination), are mentioned: low treatment efficiency (NH4+, S2-); generation of trihalometanes (THMs), especially brominated ones, with unpleasant consequence upon the treated water quality, which is not proper for human consumption. | en_US |
