Biofilm growth in water distribution systems
WebJul 1, 2024 · Controlling biofilm growth in water distribution systems remains one of the major challenges. The results of this study suggest that biofilm growth and removal in the main pipe system can be, to a limited extent, controlled with different flow regimes. Water flow velocities higher than 2 m s −1 reduced bacterial adhesion significantly, but WebDec 1, 2024 · The presence of biofilms in drinking water distribution systems (DWDS) is a global public health concern as they can harbor pathogenic microorganisms. Sodium hypochlorite (NaOCl) is the most commonly used disinfectant for microbial growth control in DWDS. However, its effect on biofilm removal is still unclear.
