Control Strategies for the Mitigation and Removal of Attached Manganese Biofilms

摘要

Biofilm formation and manganese oxidizing bacteria (MOBs) in water transmission and distribution systems can lead to a wide array of water quality issues, operational problems, and negative hydraulic impacts. To investigate possible methods to control biofilm formation, a study using chlorine dioxide (ClO2) and sodium hypochlorite (NaOCl) was performed with rotating annular reactors (ARs). Results showed that low (0.5??mg/LasClO2) and high (1.0??mg/LasClO2) doses ofClO2, and2.0??mg/
