Abstract

The paper presents results of qualitative analysis of non-regulated organic pollutants in municipal wastewater and treated municipal wastewater with flocculation, ozone and UV process using GC-MS. The majority of the pollutants in the influent of the municipal wastewater treatment facility were either food related or due to the diffuse discharge from products used both in households and in industry. In the case of biological treatment process removed some organic pollutants effectively. But some organic pollutants were not removed with biological treatment. Thus, additional steps to improve the quality of effluent municipal wastewater will require a more rigorous control of consumer products used in household and municipal wastewater process using advanced treatment processs. The obtained data contributed to the evaluation of pollutants discharges to the ecosystem as well as to the characterization of pollution sources in the basin.
