What Is Biofilm in Water Systems? Causes, Risks and Control Methods
Posted by David Cannon on 12th Oct 2026
Biofilm can become a persistent problem in water systems when microbial growth accumulates on equipment, membranes, and other wetted surfaces. In systems with biofilm in water pipes or biofilm in water lines, microbial deposits can contribute to water quality concerns, biological fouling, flow restrictions, and conditions that may promote corrosion or interfere with equipment performance.
Established biofilm can also be difficult to control because microorganisms within the biofilm matrix may be
