HL-CONT Plus OceanCruise
The HAMANN HL-CONT Plus OceanCruise range of advanced wastewater treatment systems (AWTS) 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).
Combining the physical and biological treatment technologies, HL-CONT Plus OceanCruise systems eliminate the need for filters and membranes.
Another key feature is the modular design.
HL-CONT Plus OceanCruise plants consist of four separate modules, which can be installed apart from each other, even on different decks, which gives tremendous flexibility when it comes to fitting a sewage system into a hull.
Moreover, ship’s tanks may be converted to become the biological treatment modules.
The footprint of a HAMANN HL-CONT Plus OceanCruise system can be significantly smaller than that of a comparable system from other manufacturers.
KEY FACTS - HL-CONT Plus OceanCruise AWT systems
ALASKA & BALTIC SEA COMPLIANT
HAMANN HL-CONT Plus OceanCruise advanced wastewater treatment systems (AWTS) comply with the strictest regulations on sewage discharge in place today:
The IMO‘s MEPC.227(64) section 4.2 regarding the Baltic Sea and MARPOL Annex IV special area as well as US 33 CFR 159 Subpart E regarding the waters of the state of Alaska.**
EASE OF OPERATION & LOW MAINTENANCE
Routine functions on HAMANN plants are fully automatic and no specialised skills are required to operate them.
The technology eliminates the need for filters and membranes, which would require a lot of work for regular cleaning and replacement.
The open design of the DAF units allows instant access to all components for inspection and service purposes, why routine maintenance on HAMANN plants can be carried out quickly and easily by the crew on board.
SMALL FOOTPRINT
Due to their technology and design, the footprint of HAMANN HL-CONT Plus OceanCruise advanced wastewater treatment systems (AWTS) can be significnatly smaller than comparable
systems from other manufacturers.
Ship tanks can be converted to MBBR modules which further reduces the already small footprint of the system.
RETROFIT-FRIENDLY MODULAR DESIGN
Each of the four separate modules of a HAMANN HL-CONT Plus OceanCruise system is only a fraction of the size of a comparable single block plant, why it is much easier to find the space to install them, – especiallly on an existing vessel.
In addition, the DAF units of HAMANN systems can be delivered dismantled for assembly at the location of installation on board the vessel. – A huge benefit in retrofit projects, where this feature can often spare cutting an opening into the hull, saving a lot of time and money.
COMBINED BLACK WATER & GREY WATER TREATMENT
As all HAMANN plants, the HL-CONT Compact systems are designed to treat black water and grey water as a sewage mixture in the same process.
This benefits the performance and reliability of the sewage treatment system as well as the environment.

SEWAGE TREATMENT TECHNOLOGY - HL-CONT Plus OceanCruise
PREPARATION:
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.
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 their 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.
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 Plus sewage treatment plant is safe to be discharged overboard (if permitted).
