- Abstract:
- The drinking water distribution system is a critical infrastructure that transports drinking water from the water treatment plant to end-users. However, during the distribution process, there would be a problem of water quality degradation. The growth and detachment of biofilms on pipe walls were the important reasons which affecting water quality. This article presents a critical review of research on the growth and detachment process of biofilms, the structure of biofilms, and the reasons why they detach into the bulk water. The results indicate that disinfection, nutrient concentration, and changes in hydraulic conditions can cause the biofilm to detach into the bulk water, which affects water quality. Therefore, care must be taken with the detachment of biofilm to ensure the safety of drinking water in the drinking water distribution system.
