19. Drinking Water, River Water Purification Systems, Case Study Brcko/Bosnia and Herzegovina

The following chapter shall provide a comprehensive overview of the water treatment plant (WTP) located in Brčko, Bosnia and Herzegovina. Due to the rising drinking and industrial water demand, VA TECH WABAG© was commissioned to build a second WTP for the production of drinking water from surface water. The WTP comprises multi-barrier treatment system focused on the removal of suspended matter and total organic carbon (TOC). The raw water is abstracted from the adjoining Save River and pre-oxidized before being flocculated and clarified in lamella clarifiers. The downstream filtration then removes the remaining suspended solids. The following main ozonation and biological activated carbon (BAC) filtration are responsible for the elimination of organic compounds and other contaminants. Finally, the BAC filtrate is disinfected with chlorine dioxide (ClO₂) and distributed into the water network. The presented technologies are interlinked with other chapters, thus providing a more detailed explanation.
