Disinfection is one of the main parts of water treatment processes, allowing to maintain microbiological safety. However, it carries the risk of the formation of by-products in the drinking water, which in the long term, may pose
a threat to consumer health. There are many methods to reduce the level of disinfection by-products (DBP) formation, depending on the type and quality of water abstraction. However, this process cannot be fully eliminated in water supply systems with a high potential for their generation. Both the need to ensure the microbiological safety of tap water and the need to reduce the formation of DBP make disinfection a technological process of particular importance in the procedures of managing the safety of water delivered to consumers.
On the example of Municipal Heat Energy, Water Supply and Sewage Company Ltd in Środa Wielkopolska city, the article presents the process of identifying threats resulting from the creation of UPD and actions aimed
at minimizing or eliminating this threat. In connection with the above, preliminary studies were carried out
at the Company, which showed the effectiveness of using coagulation to reduce the potential of UPD formation in the treated water. These activities used a systemic approach to water safety based on risk analysis and management. The aim of the study was to analyze the potential risk of UPD formation in water intended for human consumption and to assess the technological effectiveness of coagulation as an effective protective barrier in risk management.
