Marine growth, Seashells, Mussels, Barnacles

Marine growth refers to the settlement and accumulation of mussels, seashells, and barnacles on inner pipe surfaces when seawater is used for drinking water production or cooling purposes. This phenomenon occurs when larval organisms pass through filters and settle in low-flow areas or favorable conditions within piping systems. As these organisms grow, they create increasingly thick shell layers that accumulate at narrow points, particularly at heat exchanger inlets, significantly reducing water flow and heat exchanger capacity.

The Merus technology addresses marine growth through two mechanisms: first, by maintaining clean, smooth pipe surfaces through treatment that prevents incrustation and corrosion, eliminating settlement sites for larvae; and second, by creating a stable film of pure water at the surface that reduces friction and prevents larvae from gaining sufficient grip to settle and grow. This chemical-free approach proves environmentally preferable to traditional biocide treatments like chlorine, which are increasingly restricted by environmental regulations and can harm marine ecosystems.
