During the last cruise ship season in Alaska, the sewage treatment systems in sewage treatment treatment systems developed by Wärtsilä Water & Waste achieved a 98.2% compliance level against the stringent verification tests conducted by the Alaska Department of Environmental Conservation (DEC).
This figure, based on publicly audited data, places the company above the overall fleet average (94.7%) and ahead of the results obtained by other brands in the sector (90.8%).
MBR technology for sewage treatment on cruise ships
The solutions from Wärtsiläsolutions, based on Hamworthy membrane bioreactorsmembrane bioreactors combine biological processes and advanced filtration. This technology allows stable, high quality effluents to be obtained without the use of chemicals.
In addition, the system features real-time monitoring sensors that integrate with remote technical support, ensuring consistent results across different types of vessels and routes.
Transparent evaluation and external verification
Each cruise ship operating in Alaskan waters must undergo periodic sampling of treated water for laboratory analysis. The results are published on an individual basis, making the program one of the most stringent and open in maritime environmental regulation. The high performance of Wärtsilä systems in this environment demonstrates their technical robustness and operational reliability.
Our design prioritizes compliance from day one. Ongoing technical support and system adaptability are key to maintaining this level of compliance in demanding conditions such as Alaska.
