KEY FEATURES OF HAMANN SEWAGE TREATMENT PLANTS

MINIMISED FOOTPRINT
Due to our technology and design, the footprint of HAMANN sewage treatment plants (STP), or marine sanitation devices (MSD) can be up to 70% smaller than comparable systems from other manufacturers – depending on the model.

DISMOUNTABLE FOR RETROFITTING
HAMANN plants can be almost completely assembled at the location of installation on board the vessel to facilitate movement to the site through most doors and hatches. A huge benefi t in refi t projects, where this feature can often spare cutting an opening into the hull, saving a lot of time and costs.

EASE OF OPERATION & LOW MAINTENANCE
Routine functions on HAMANN plants are fully automatic and no specialised skills are required for daily operation. Our technology eliminates the need for fi lters and membranes, which would require a lot of work for regular cleaning and replacement. Routine maintenance on HAMANN plants can be carried out quickly and easily by the crew on board. The open design allows instant access to all components for inspection and service purposes.

RELIABILITY
Proven technology and manufacturing to the highest quality standards combined with straightforward operation and low maintenance requirements give HAMANN plants the reliability and longevity they are known for around the world.
