(Bio)Fouling

Fouling and biofouling are among the most persistent and costly problems in industrial water systems – from boilers and heat exchangers to cooling towers and seawater intakes. Whether it’s caused by mineral particles, corrosion debris, or biofilm-forming bacteria, these layers accumulate over time, disrupting flow, lowering thermal efficiency, and sheltering corrosion-causing microbes.

(Bio)fouling doesn’t just make your system dirty,  it makes it unstable, inefficient, and vulnerable.

What causes (bio)fouling?

  • Warm, stagnant, or low-flow water zones
  • Inorganic particles (like rust or scale) accumulating in pipes
  • algae, bacteria, or marine organisms forming sticky biofilms
  • Inadequate microbial or chemical control
  • Lack of early monitoring and system mapping

HydroGreen’s (Bio)fouling Defence Strategy

We combine real-time monitoring, smart disinfection, and non-chemical disruption to control fouling at every level – starting with root cause identification and sustainable prevention.

✅ Merus® Technology (by Pronomar)

Using a patented oscillation ring, Merus® disrupts both organic and inorganic fouling. It alters the behaviour of minerals, bacteria, and biofilm-forming organisms, preventing deposits from taking hold and making them easier to flush away.

  • Non-invasive installation
  • Works 24/7 without adding chemicals
  • Proven results in seawater and freshwater systems

✅ Biofilm Monitoring (by Lagotec)

Early detection is key. Lagotec sensors continuously monitor biofilm activity on key surfaces inside your system. This enables proactive treatment decisions — before performance is affected.

  • Real-time data on microbial growth
  • Helps optimise biocide dosing
  • Validates treatment effectiveness
