This paper presents results of wastewater examination from Belgrade sewerage system (BKS) which are discharged into the river Sava (Fair) and river Danube (Visnjica). Examinations were conducted within the project Eight monitoring spots and are compliant with European Directives concerning wastewater management. Project Eight monitoring spots consist of: continuous measurements of physical and chemical parameters (pH, temperature, redox potential and conductivity), sampling of wastewater during 24 hours, measuring flow rate and analyzing the quality of wastewater from monitoring places located at the discharges into rivers Sava and Danube. This paper shows examination results collected at two discharge points out of eight which are included in this project. The analysis of the quality and the quantity of wastewater sampled continuously during 24 hours, the effects of industrial pollution on them and total pollution load from these two collectors on the recipient is given.

The microbiological quality of the groundwater was monitored by determining relevant physiological groups of bacteria (organotrophic bacteria) which are indicators of water organic pollution. Standard high nutritive medium (Nutrient Agar) and low nutritive medium (R2A agar) were used. The enzymatic activity was also estimated based on IFA determination (index of phosphatase activity). According to the number of organotrophic bacteria and categorization by Kohl (Kohl, 1975) water is generally classified in category II. IFA showed variation of water quality, which varied from polluted to very pollute. The results showed organic pollution of groundwater and confirmed the sensitivity of enzymatic methods. In addition, cultivation methods confirmed superiority of low nutritive media.

It has been established that processing by CTA - peat, under normal pressure, significantly reduces COD of tested wastewater, but at the same time, quickly comes to a stoppage, due to clogging. Results show that filtration process needs to be done under increased pressure. Based on gained results it could be concluded that CTA-peat represent efficient means of eliminating organic matters from wastewaters.
