Biofilm Awareness Week is an important reminder that one of the most significant threats to a vessel’s water system is also one of the least visible. Biofilm forms the underlying structure that enables Legionella, Pseudomonas, and other waterborne pathogens to survive, multiply, and spread throughout the potable water networks of yachts and marine vessels.
At Octo Marine, we help Yachts and marine vessels identify, monitor, and reduce biofilm so they can stay compliant and safe.
What Is Biofilm and Why Does It Matter Aboard Yachts and Marine Vessels?
Biofilm is a sticky, resilient layer of microorganisms that adheres to the inner surfaces of pipes, tanks, hoses, filters, and other water-system components. Once established, it forms a protective shield that allows bacteria to survive, multiply, and spread—even when hot water, flushing, or traditional disinfectants are present.
Key factors that promote biofilm development and the growth of Legionella, Pseudomonas, and other waterborne pathogens include:
• Warm or fluctuating water temperatures above 20 °C
• Infrequent use of outlets, especially those not used daily and not flushed at least weekly
• Low, inconsistent, or unstable disinfectant residuals
• The presence of sediment, scale, corrosion, or deposits within tanks and pipework
• Poorly maintained filters (particularly those not replaced monthly), hoses, and fixtures
How HydrasilAg+ Helps Protect Your Vessel.
HydrasilAg+ offers a powerful and targeted solution for marine potable-water systems. Its unique stabilised hydrogen peroxide and silver formulation penetrates and disrupts biofilm, maintains a long-lasting disinfectant residual throughout the entire distribution system, and provides continuous protection against bacterial regrowth. Unlike traditional disinfectants that struggle to break through biofilm, HydrasilAg+ works effectively within pipes, tanks, and water treatment equipment, helping to keep your yacht’s water system clean, safe, and compliant.
