HL-CONT Plus Rivercruise

Advanced Wastwater Purification for Inland Shipping

HAMANN HL-CONT PLUS RIVERCRUISE – advanced wastewater purification for inland shipping. Modular design for maximum flexibillity. Demountable to simplify retrofit projects. Small footprint for efficient use of space.


Benefits of HL-CONT Plus Rivercruise – Advanced Wastewater Purification for Inland Shipping

Small Footprint

HL-CONT Plus RiverCruise systems only require roughly one third of the space of comparable systems by other manufacturers, using space efficiently. A ship’s tank can be upgraded or converted to act as an MBBR (Moving Bed Bioreactor) module, which further reduces space requirements.

Modular Design – Flexible Installation

HL-CONT Plus RiverCruise advanced wastewater purification for inland shipping consist of three separate modules that can be installed separately from each other, even on different decks, offering outstanding flexibility.

Dismountable for Easy Retrofits

Both Dissolved Air Flotation (DAF) units of a HL-CONT Plus RiverCruise system can be completely dismantled so that the largest components are small enough to fit through standard size hatches and doors. This also makes our wastewater purification systems the perfect retrofit solution.

Advanced Wastewater Purification Technology

Dissolved Air Flotation and Moving Bed Bioreactors

HAMANN HL-CONT Plus RiverCruise advanced wastewater purification for inland shipping use a combination of our Dissolved Air Flotation (DAF) and Moving Bed Bioreactor technologies. The two DAF (Dissolved Air Flotation) units separate the suspended solids (TSS) and reduce the chemical (COD) and biological (BOD) oxygen demand. In the Moving Bed Biorector (MBBR) the carbon compound is eliminated (BSB5, CSB and TOC). The principle of our DAF technology can be observed when opening a bottle of sparkling water: Pressurized water can hold gas that escapes rapidly when the pressure is released. In our system the macerated sewage is saturated with air under pressure. By suddenly releasing the pressure we create microbubbles that adhere to suspended solids in the sewage and float them to the top of the flotation tank. The accumulated sludge is skimmed and lead to a sludge tank.

Uncompromising Quality

Top Quality Components and Materials

We use only the best components from reputable manufacturers and carefully select all materials to meet the requirements of operation in a maritime environment. HL-CONT Plus RiverCruise sewage treatment plants are made entirely of metal; all parts in contact with the wastewater are made of stainless steel.

Designed and Manufactured in Germany

All our plants and systems are designed and manufactured in Hollenstedt, Germany according to our DNVGL-accredited ISO 9001 quality management system.

Proven Track Record in Marine Wastewater Treatment

HAMANN delivered its first sewage treatment plant back in 1972, even before the first IMO resolution on sewage treatment was adopted. Since then, we have installed over 5.500 sewage treatment systems on superyachts, ferries, cruise ships and naval vessels all over the world.

Unrivalled Performance in Wastewater Treatment

Ease of Operation

The routine functions are fully automatic, no special crew skills are required to operate a HL-CONT Plus RiverCruise advanced wastewater purification system.

Ultimate Reliability

Proven technology and manufacturing to the highest quality standards combined with straightforward operation and low maintenance requirements give our wastewater treatment systems the reliability they are known for around the world.

No Membranes or Filters – Minimun Maintenance Requirements

There are no membranes or filters in HAMANN HL-CONT Plus RiverCruise advanced wastewater purification systems, because they have to be cleaned, maintained and replaced regularly. All routine maintenance work can be carried out quickly and easily by the crew on board. The open design allows easy access to all components for inspection and service purposes.
