摘要
This study shows examination results pertaining to the assessment of operation of coalescence separations installed on the way of flow of rainwater and meltwater to Slupia river. The study was performed within Slupia river water protection programme. Content of total suspension as well as concentrations of organic compounds from the BTEX and paraffin group were determined in samples taken from the inlet to and outlet from the separators. It appears from the study performed that in no case admissible content (> 15 mg/dm(3)) of determined petroleum-derived substances had occurred in the samples of rainwater and meltwater and a high degree of elimination of those compounds, due to separators operation, was achieved. In 13 samples taken from the separator outlet, the admissible total suspension content was exceeded (above 100 mg/dm(3)). Efficiency of all separators operation reflected in the elimination of total suspension amounted, on average, to 67.5%. The lowest total suspension elimination efficiency has been noted for separator No. 14 (40%).
