The closed loop is the most frequently used system. The seawater used in the process is continuously re-circulated. Detailed information can be found in our brochure.

How does it work?

Instead of being re-used, the process water is discharged directly back to sea while complying fully to the IMO regulations. Optionally the seawater can be pumped through a water treatment system to remove all solids and oil. Detailed information can be found in our brochure.

How does it work?

The hybrid scrubber system can run in both closed or open loop mode. Water is either re-circulated or discharged back to sea.

Damen Green Solutions’ latest development is a one step scrubber wash water aftertreatment solution that ensures a better, safer environment.

Several countries have already banned open-loop systems discharging wash water in their ports. Vessel operators are being advised to switch to close-loop operation. With this unique aftertreatment system a simple integrated solution ensures both compliance in those regions and a cleaner environment.

This filter solution collects inlet water from the scrubber wash water collection tank. The filter can handle any wash water in one step and creates dry sludge with up to 85% dry content and clean effluent water in accordance with descriptions given in MEPC 259(68).

The system is easy to operate and needs no difficult chemical injections. The system is also designed for easy mainteance.

The system can be designed as a skidded solution or as a modular system.

Retrofit projects for scrubbers will have an impact on the existing vessel. Quite some systems need to be installed and commissioned.

The owner will always decide at which place in the world such a retrofit project will be executed. Damen simply will, in close cooperation with the owner, offer such installation work at that place. This can be reached by forwarding the required material package to this particular county/yard together with a Supervisor. This Damen Supervisor can work together with the local yard management/personnel to execute the scrubber installation work.
