Biological sewage treatment

Sewage treatment with no efforts

Clean Sewage

CleanSewage Bio is designed to put all efforts with wastewater treatment to the lowest level possible. The accessibility from one side allows ship designers to plan space in the engine room on a whole new level.

Operators and crew are pleased with a hygienic no-touch-cleaning system, an intuitive status control allows checking at a glance, whether the system is running or intervention is necessary. Thereby CleanSewage Bio works with a proven 3-chamber-treatment concept that ensures highest water quality according to MEPC.227(64).
