Massive bryozoan colony

Because of the large volumes of water involved, chemical treatment is usually recommended only as a last resort. Our strategies are more often based on finding and eliminating the causes of bryozoan build-up in the system. Seasonal climate, water chemistry, plant configuration, and the fouling species are important factors in designing an effective control strategy.

Bryozoans threaten industrial cooling systems when an accumulation that has been building over time suddenly lets go. A damaging slug of bryozoans can range in volume from a square inch to more than a square foot. It can overwhelm inlet filters, plug condensers, disrupt instrumentation, and disable emergency circulation.

Common Powerplant fouling micro-organisms:

• Plumatella vaihiriae, Fredericella indica, Paludicella articulata
• Cordylophora caspia
