Biofilm microbial community characteristics of stainless steel adsorbed with silver ions

The formation of biofilm on pipe wall is a common concern in distribution system, which spurred researchers to develop more effective scheme for water disinfection. In the present study, a strategy to synthesize the silver-loaded stainless steel (SS-Ag) as an antibacterial material was proposed. The antibacterial efficiency of SS-Ag in a long-term period and its effect on the microbial community of biofilm were investigated at lab-scale. This work provides a new method for controlling biofilm fouling to ensure the biosafety of water distribution system.
