Ballast Water Treatment Unit

Tehado designs and builds complete ballast water treatment systems with capacities ranging from 100 to 2,500 m³/h, for both newbuilds and refits. Together with our parent company, Marine Service Noord, we manage the entire process, from engineering and assembly to installation and commissioning. To date, we have delivered multiple systems for leading names in the maritime industry.

Based on the functional requirements and vessel operating profile, we provide independent advice on the most suitable OEM and treatment technology. We take into account applicable regulations, operation in salt, fresh and brackish water, and the Total Cost of Ownership (TCO), including both capital and operational costs. Depending on the application, solutions can be based on UV technology, electrolysis or electrocatalytic treatment.

For newbuilds, we design compact, pre-assembled skids wherever possible, integrating components, instrumentation and pipework efficiently. For refits, we opt for a modular configuration, depending on the available space. Using 3D engineering in Cadmatic and 3D scans of existing engine rooms, we carefully prepare the integration process and minimise installation time on board.
