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.

固体表面上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动发生的栖息地。工程和环境系统中的生物膜发展是世界各地水工业中最重要和最持久的问题之一，会导致过滤系统和管道的腐蚀、膜生物污垢和堵塞。由于在不同的大量流体和工程条件下形成的微生物组成和生物膜特性高度多样化，因此没有单一的一劳永逸的处理方法可以有效控制生物污垢。拟议的研究旨在解决埃德蒙顿市地下水引水系统的生物污垢控制需求。通过在地下水引水管中进行现场杀菌剂处理研究，并评估地下水系统中生物膜的形成和消除，拟议的研究将（i）确定有效的杀菌剂类型和剂量策略，以及（ii）建立地下水生物污垢控制策略。
