HAMANN HL-CONT PLUS sewage treatment plants (STP), or marine sanitation devices (MSD), are available in many different sizes, offering treatment capacities from 3000 litres/day up to 288000 litres/day. Stainless steel construction on frames, top-quality components and extensive customisation options make these systems the all-rounders in the our STP program. HAMANN HL-CONT PLUS plants are renowned for their compact dimensions. In addition, they can be almost completely assembled at the location of installation on board the vessel.
KEY BENEFITS HAMANN HL-CONT PLUS
EXTENSIVE CUSTOMIZATION OPTIONS
We offer a wide range of customization options for HL-CONT PLUS sewage treatment plants. This enables us to supply a system that exactly meets our customer’s specifications.
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 benefit in refit 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 HL-CONT PLUS plants are fully automatic and no specialised skills are required for daily operation. 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.

HAMANN HL-CONT PLUS SEWAGE TREATMENT TECHNOLOGY
CREATING THE SEWAGE MIX
HAMANN HL-CONT PLUS 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.
The sewage mixture from the sewage mixing tank is first run through a macerator to chop up solid and fibrous components.
By means of our Dissolved Air Flotation (DAF) technology, HAMANN HL-CONT PLUS 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.
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 PLUS sewage treatment plant is safe to be discharged overboard (if permitted).
