HAMANN HL-CONT PLUS OceanCruise systems are designed to meet or exceed the highest current standards for sewage and greywater discharge. These advanced wastewater treatment systems are suitable for ships operating in the waters of Alaska or the Baltic Sea (MARPOL Annex IV special area).
Aeration and circulation are two important aspects of sewage systems onbard ships. The contents, the ratio between black water and greywater and the condition of the sewage mix that is fed into a sewage treatment plant have a major impact on the treatment performance.
Sewage transfer management and sewage storage are important tasks of the sewage system on board any vessel. The more separate tanks are used on board and the longer the journey times between ports, the more important it becomes to have an intelligent transfer management system on board that can perform these tasks.
