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 our 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. This 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 up to 70% smaller than that of a comparable system from other manufacturers.

KEY BENEFITS OF HL-CONT PLUS OCEANCRUISE AWT SYSTEMS
ALASKA & BALTIC SEA COMPLIANT
HAMANN HL-CONT Plus OceanCruise systems are certified according to IMO MEPC.227(64) incl. Sect.4.2 and EU MED B & D. They comply with US 33 CFR 159 Subpart E (Alaska) to obtain a permit under the Commercial Passenger Vessel Environmental Compliance (CPVEC) Program of the Alaska Department of Environmental Conservation (ADEC).**
MODULAR DESIGN
HL-CONT PLUS OceanCruise systems consist of four separate modules: Two Dissolved Air Flotation (DAF) units and two Moving Bed Biofilm Reactors (MBBR). Each module can be installed in a different location apart from the other modules, offering exceptional flexibility and the best possible use of space. Ship tanks can be converted to MBBR modules, further reducing the already small footprint of the system.
CUSTOMISED SYSTEMS
HL-CONT PLUS OceanCruise systems are customised to the individual requirements of the customers and the respective conditions on board the vessels.

HL-CONT PLUS OCEANCRUISE TREATMENT TECHNOLOGY
PREPARATION: CREATING THE SEWAGE MIX
HAMANN HL-CONT PLUS OceanCruise 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.
PRE-TREATMENT
The sewage mix 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 we separate the suspended solids (TSS) and reduce the chemical (COD) and biological (BOD) oxygen demand. With the addition of a flocculant, the solids create a sludge foam on the surface, 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.
BIOLOGICAL TREATMENT
The pre-treated sewage is drained into the two-stage biological treatment of the HL-CONT PLUS OceanCruise system, consisting of two Moving Bed Biofilm Reactors (MBBR). Circulating between the denitrification and nitrification stages, bacteria metabolize the nitrogen compound in the sewage.
FINAL TREATMENT
Since the bacterial processes in the biological treatment also produces biomass, the solids have to be removed in the second DAF unit. The flocculant used in this process also removes the phosphorus.
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 HL-CONT PLUS OceanCruise plant is safe to be discharged overboard (if permitted).
