In recent years the analyzes keeping us updated on the content of biodegradable organic substances and the possibility of secondary propagation of microorganisms in drinking water have come into the center of our attention. The drinking water that does not allow propagation of microorganisms even at the minimum residual concentrations of disinfectants is labeled as biologically stable water. Permanganate chemical oxygen demand (CODMn), absorbance at 254 nm (A254) and culturable microorganisms are commonly determined as frequently monitored parameters that indicate the presence of organic substances The highest values of CODMn and A254 were measured in raw water. During the water treatment a gradual decrease in both indicators was observed. The largest decrease was recorded after the coagulation with sand filtration. The highest biological recovery was recorded in July. The water was dominated by the filamentous cyanobacteria of Aphanizomenon. Preozonization was followed by a slight decrease in the numbers of organisms caused probably by the decay of some cells due to ozone exposure. Coagulation with sand filtration resulted in the removal of most organisms from water. Further elimination occurred at GAU.
