摘要

The aims of the work and research question deals with the removal of two natural nitrogen compounds,nammonium and nitrate and an organic compounds from groundwater in the sensitive aquatic area (CuroniannSpit, Lithuania). The effects of both ammonium presence and nitrate compounds were studied using naturalngroundwater in the water treatment plants. Organic compounds were studied at Total Organic Carbon (TOC), DissolvednOrganic Carbon (DOC), Color (Pt scale) and UV methods. The amines were varied in the range of 0.11–n0.32 μg Lu00011. At ammonium concentration of 790 μg Lu00011, the amines formations were close to 0.66 μg Lu00011 maximumnobtained in the groundwater. The highest ammonium removals were obtained at water treatment plantsnof approximately 15 mg Lu00011 TOC. Continuous tests showed a linear relationship between TOC and DOC concentrationnrates. The conclusions drawn that the most biodegradable compound was the ammonium. The TOC/DOCnrates increased with the decreased of ammonium concentrations. Optimal process conditions in this work werenobtained at the TOC and DOC of approximately 16 and 14 mg Lu00011, respectively, with high efficient of ammoniumnremoval, as well as minimum amines formation rate.
