Abstract

The effectiveness of treatment using sequential biological reactor (SBR) technology is demonstrated at the Domžale-Kamnik Central wastewater treatment plant (WWTP). The tests were done with the Allium metaphase test and show the degree of genotoxicity, by observing the aberration of the metaphase chromosomes of the onion plant Allium cepa L. (A. cepa). The results were compared with final treated effluent (FTE) samples and river samples before and after the outflow treated water. The third river sample looks like a negative control (–K), since the sample does not show toxic and genotoxic load. With this, we determined the: (i) effects of treatment at the WWTP and, (ii) as a result, the quality of the Kamniška Bistrica (KB) river after the outflow of water from the WWTP. The lower the level of cytotoxicity and genotoxicity in wastewater, the fewer damaged chromosomes in the chromosome set test plant onion A. cepa, the greater the treatment effect in the WWTP.
