NOx emission reduction
GEA bilgEGR Solution is a combined Exhaust Gas Recirculation (EGR) and oily bilge water system designed to treat water on board ships. After treatment, the purified water can be discharged into the sea.

When implementing Exhaust Gas Recirculation (EGR) technology in marine engines, it is necessary to consider the treatment of EGR wash water before its discharge into the sea.
During the EGR process, the recirculated exhaust gas come into contact with contaminants such as soot, sulfur compounds, and acidic components. As a result, the wash water generated from cleaning the EGR system can contain pollutants that need to be treated to ensure compliance with environmental regulations.
The GEA bilgEGR Solution is a system designed for both bilge water treatment and EGR wash water purification. GEA bilgEGR Solution is a practical installation for minimizing the equipment and installation costs associated with the discharge of EGR wash water and bilge water on board. This is achieved through proper design and control of the combined system.
