According to the water quality monitoring for the human consumption in Croatia for 2018, most of the water from locaI (and individual) water supply systems w ere unsafe to drink, primarily due to the presence of microbiological and heavy metal contamination, Commonly used w ater disinfection process with chlorine and its compounds can produce carcinogenic byproducts, such as chlorinated hydrocarbons and nitrosamines. Also, conventional methods for removal of heavy metals, such as reverse osmosis and ion exchange, are very complex and expensive in general. According to the recent research, advanced oxidation and electrochemical processes show the possibility for efective removal of various pollutants in water purification process. Therefore, the purpose of this project is to determine the applicability of the electrocoagulation (EC) and ultrasound (US), as an advanced oxidation process, for removing microbial and heavy metals contamination in drinking water preparation.

The finaI goaI of the project is to construct a small water purification system (EC and US reactor with settling tank) with optimum configuration defined on the project research, that will include different process parameters, as w ell as the design of the system, ln order to create a continuous water puriflcation system. The lack of the possibility for continuous treatment is one of the greatest shortcomings of the existing research. The research will undergo through five phases in which a research group and laboratory will be established and the EC and US efficiency for pollutants removal will be investigated for different process parameters. Then, through numerical modelling, the necessary design of the system elements will be defined in order to achieve the continuity of the purification process. Also, the effects of the system design on the removal efficiency will be investigated. Finally, the pollutants removal efficiency will be determined on the constructed and optimized system.
