Revenue model
- Sewage Treatment Equipment Sales: HAMANN generates revenue primarily from selling sewage treatment plants (STP), advanced wastewater treatment systems (AWTS), and related marine sewage system components including grease separators, conditioning systems, tank transfer systems, and the BlueFloc flocculant product. Products are sold directly to shipyards during newbuild projects and to ship owners/operators for retrofits. The company offers extensive customization options for each project, with systems ranging from compact units (HL-CONT Compact) to large-scale cruise ship installations.
- Technical Consulting & System Design Services: HAMANN provides expert consultancy on sewage and greywater systems from the planning stage through to operation. The company conducts workshops with ship design companies and naval architects before or at the beginning of projects, and works closely with shipyard engineers during detail construction. This consulting is integrated with equipment sales.
- After-Sales Support & Service: With over 40 sales agents and service partners in the HAMANN GLOBAL NETWORK, the company provides customer support and technical field service around the globe. Remote support services are also offered using audiovisual communication tools, reducing travel requirements.

HAMANN product offering
Product offeringCore offering
HAMANN AG designs and manufactures marine sewage treatment plants (STP), advanced wastewater treatment systems (AWTS), grease separators, conditioning systems, tank transfer systems, and flocculant products for installation on yachts, cruise ships, ferries, naval vessels, and offshore platforms. All products are engineered and built in Hollenstedt, Germany, with proprietary Dissolved Air Flotation (DAF), Moving Bed Biofilm Reactor (MBBR), and UV disinfection technologies. The company sells directly to shipyards and ship owners via customized project quotations, supported by technical consultancy and a global after-sales service network.
Product overview
HAMANN AG offers a comprehensive marine sewage system portfolio centered on their HL-CONT sewage treatment plant (STP) and HL-CONT Plus OceanCruise advanced wastewater treatment system (AWTS) product lines. The HL-CONT Compact and HL-CONT Plus STPs form the core offerings, treating black water and grey water mixtures from 3,000 to 288,000 litres/day for yachts, cruise ships, ferries, and commercial vessels. The advanced HL-CONT Plus OceanCruise AWTS adds biological treatment using Moving Bed Biofilm Reactors (MBBR) for compliance with Alaska and Baltic Sea special area requirements. These core treatment systems are complemented by supporting products: GS Compact grease separators for galley water pre-treatment, TA/TAC/TC conditioning systems for sewage holding tank management, and TMS PLUS tank transfer systems for optimizing tank capacity utilization. All systems utilize HAMANN's proprietary Dissolved Air Flotation (DAF) technology and are manufactured in Hollenstedt, Germany to ISO 9001 quality standards, with over 5,500 installations supplied since 1972.

Products and services
- HAMANN HL-CONT Compact Compact sewage treatment plant optimized for common marine operating scenarios up to 3,000 litres/day. Constructed in stainless steel with two alternative layouts (A and B) for mounting flexibility, and certified to IMO, EU-MED, and UK-MER standards. Targeted at yachts, smaller commercial vessels, and any installation where engine room space is constrained.
- HAMANN HL-CONT Plus Versatile marine sewage treatment plant available in capacities from 3,000 to 288,000 litres/day. Stainless steel construction with extensive customization, optional on-site assembly to support retrofits through standard doorways, and certification options including IMO, EU-MED, UK-MER, or USCG Type 2. Deployed across cruise ships, ferries, naval vessels, research vessels, and commercial fleets.
- HAMANN HL-CONT Plus OceanCruise Advanced wastewater treatment system (AWTS) that combines physical and biological treatment technologies for the strictest discharge regimes. Four separate modular units can be installed apart from each other on different decks, with DAF units deliverable dismantled for assembly at the installation site. Achieves Alaska and Baltic Sea compliance via IMO MEPC.227(64) Section 4.2 and eliminates filters and membranes.
- HAMANN GS Compact Grease Separator Grease separator for galley water treatment that keeps the influent to STPs, MSDs, or AWTS free from fats, oils, and grease. Uses simple gravity separation technology and is TÜV Rheinland certified to DIN EN 1825 and DIN EN 4040, supporting compliance on vessels with significant galley effluent such as cruise ships and ferries.
- HAMANN TA/TAC/TC Conditioning Systems Conditioning systems for sewage holding tanks that prevent anaerobic conditions, prevent sedimentation, and keep sewage sludge pumpable, supporting reliable downstream treatment on commercial vessels and cruise ships.
- HAMANN TMS PLUS Tank Transfer System Tank transfer system that manages transfers between holding and mixing tanks, optimizes use of tank capacities, and prepares sewage mixture for treatment. Supports automatic and semi-automatic operation to reduce manual intervention on board.
- BlueFloc Flocculant Flocculant product used in HAMANN wastewater treatment systems to enhance solid separation within the DAF (Dissolved Air Flotation) process, creating larger flakes that float upwards to improve effluent clarity.

HAMANN competitors and assessment
Company assessmentBroad incumbents
- Wärtsilä: Large marine systems integrator with environmental solutions including sewage and wastewater treatment; overlaps with HAMANN in cruise and commercial vessel tenders, often bundling sewage into broader scope-of-supply contracts.
- DESMI Group: Danish marine equipment supplier offering pumps, ballast water treatment, and oil-water separators; overlaps with HAMANN on broader marine environmental systems and competes on integrated environmental tenders.
- Veolia Water Technologies (RWO): Provides marine sewage and wastewater solutions through legacy RWO/IPI brands; competes with HAMANN especially on large cruise and offshore platforms and offers broader water-treatment portfolio leverage.
- Alfa Laval: Global marine equipment incumbent offering a broad portfolio including ballast water treatment and freshwater generation; competes with HAMANN on integrated environmental system tenders where shipyards prefer single-vendor scope.
Emerging players
- Cathelco: UK-based marine environmental equipment supplier specializing in corrosion control, ballast water treatment, and sewage systems; a smaller niche player with partial overlap to HAMANN's marine environmental equipment portfolio.
- WWTE (Wastewater Treatment Engineering): European engineering firm focused on advanced marine wastewater treatment including biological and membrane systems; an emerging specialist with technology overlap to HAMANN's DAF/MBBR architecture, particularly relevant for stricter discharge regimes.
