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 significantly smaller than comparable systems from other manufacturers.
OPTIONAL ON-SITE ASSEMBLY FOR RETROFITS
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.

EASE OF OPERATION & LOW MAINTENANCE
Routine functions on HAMANN plants are fully automatic and no specialised skills are required to operate them. Our technology eliminates the need for filters 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.

TWO LAYOUT OPTIONS FOR THE HAMANN HL-CONT Compact
The HL-CONT COMPACT 0125 sewage treatment plant, or marine sanitation device, is available in two alternative layouts, giving even more flexibilty for installation: Layout A with shorter width but more depth and layout B with minimum depth, e.g. for mounting on walls. On delivery, all units are set up in layout A and can be quickly and easily converted by the customer if desired.
HAMANN HL-CONT Compact SEWAGE TREATMENT TECHNOLOGY
PREPARATION: CREATING THE SEWAGE MIX
HAMANN HL-CONT Compact sewage treatment plants are designed to process both blackwater and greywater as a sewage mixture. This mixture is created in the sewage mixing tank from which it is pumped into the sewage treatment plant. Depending on the tank configuration on board, greywater and/or blackwater are transferred into the sewage mixing tank to create the sewage mixture. When the filling level in the sewage mixing tank reaches a predefined level, the feeding pump of the sewage treatment plant starts to operate and the treatment process is initiated.
MACERATION
The sewage mixture from the sewage mixing tank is first run through a macerator to chop up solid and fibrous components.
TSS/COD/BOD REDUCTION
By means of our Dissolved Air Flotation (DAF) technology, HAMANN HL-CONT Compact sewage treatment plants separate the suspended solids (TSS) and reduce the chemical (COD) and biological (BOD) oxygen demand. The sewage is enriched with air under a pressure in the saturator. After being discharged into the flotation tank through the pressure release valve, the excess air forms micro bubbles. A flocculant is added in order to let air bubbles and susupended particles form larger flakes. These flakes float upwards, creating a sludge foam on the surface and leaving the clear phase in the lower part of the flotation tank. The sludge foam spills into the sludge compartment and is subsequently fed into the ship‘s sludge tank.
DISINFECTION
The already largely purified sewage is finally exposed to UV radiation to degrade the DNA of bacteria and microorganisms, rendering them incapable of reproducing and infecting. After this finishing step, the treated sewage from the HAMANN HL-CONT Compact sewage treatment plant is safe to be discharged overboard (if permitted).
