OptiSea uses new treatment to avoid fouling on seawater

SUEZ’s OptiSea uses a combination of chemical treatment and digital monitoring to prevent deposition and fouling in cooling systems that rely on seawater. OptiSea will reduce Total Cost of Operation (TCO) for customers by maximizing cycles of concentration and optimizing chemical usage, with performance assurance through real-time deposition monitoring.

Using seawater in cooling systems presents special challenges. The composition of seawater differs from place to place across the globe, and there are wide variations in the type and quantity of suspended solids. Macrofouling organisms in the water have a high growth rate, and seawater tends to have a high ionic strength. Taken together, these reasons mean that seawater cooling systems require specialized modeling, treatment, and monitoring systems to ensure peak production and optimized efficiencies, especially plate-and-frame heat exchangers.

OptiSea effectively models high ionic strength seawater, provides deposition and suspended solids control, and monitors deposition accumulation and heat transfer performance in realtime, while optimizing chemical usage with three layers of supervisory monitoring and control protection.
