Biofilm Presence in Potable Wells and Effective Chemical Treatment Strategies for Removal

Biofilm formation within groundwater wells can be extremely problematic, influencing both production and water quality. This presentation will provide an easy-to-understand explanation of the science behind biofilm formation and the role it plays in wells with regards to fouling, including its relation to coliform bacteria.

In addition, a number of treatment strategies used within the industry for biofilm removal will be presented to help arm the attendee with effective removal tactics for real world applications. An overview of common chemical products and their advantages will be covered, including; mineral and organic acids, dispersants, surfactants, and oxidizers. A special focus on improving the effectiveness of chlorination will be made as it is the most common approach for disinfection in the industry.
