Biofilm colonization on solids surfaces is a normal form of microbial growth in most environmental niches, and represents a habitat where most microbial catalyzed activity occurs. Biofilm development in engineering and environmental systems represents one of the most important and persistent issues in the water industry around the world, causing corrosion, membrane biofouling and blockage in filtration systems and pipes. There is no single one-for-all treatment for effective biofouling control because of the highly diverse microbial compositions and characteristics for biofilm developed under different bulk fluid and engineering conditions. The proposed study aims to address the City of Edmonton's groundwater diversion system biofouling control needs. Through conducting field biocide treatment studies in groundwater diversion pipes, and assessing biofilm development and elimination in groundwater systems, the proposed research will (i) identify the effective biocide types and dosing strategies and (ii) establish groundwater biofouling control strategies.

固体表面的生物膜定植是大多数环境生态位中微生物生长的正常形式，并且代表了大多数微生物催化活性发生的栖息地。生物膜在工程和环境系统中的发展是世界范围内水工业中最重要和最持久的问题之一，它会导致过滤系统和管道的腐蚀、膜生物污染和堵塞。由于在不同的流体和工程条件下形成的生物膜的微生物组成和特征高度不同，因此没有一种单一的、万能的处理方法可以有效地控制生物污染。拟议的研究旨在解决埃德蒙顿市地下水改道系统的生物污染控制需求。通过对地下水导流管道进行现场杀菌剂处理研究，并评估地下水系统中生物膜的发展和消除，建议的研究将(i)确定有效的杀菌剂类型和剂量策略，（ii）建立地下水生物污染控制策略。
