Our products
We deliver biological waste water treatment solutions for the maritime industry. We can treat both grey and black water before it is let out into the ocean. Our bioreactors live up to all rules and requirements, securing you operational flexibility while you protect marine eco systems where you operate.

What is grey and black waste water?
Grey water
Grey waste water from the vessel is all the water that comes from sinks, showers, cleaning, cooking etc.
Black water
Black waste water from the vessel is all the water that comes from toilets and medical treatments.
Bioreactors
Conventional bioreactor
Biological cleaning – removing E.coli
The bioreactor is a 100% biological treatment system, which uses a fixed biofilm combined with UV treatment for a sustainable solution. The system can handle all grey and black water from any vessel or offshore facility with no need for filters, dilution or chemicals during normal treatment.
This system lives up to IMO requirements.
Advanced bioreactor
Biological cleaning – removing E.coli, phosphorous, nitrogen and microplastic
With the advanced bioreactor, it is possible to go beyond regulations to protect the environment. It is a biological process in combination with a unique membrane treatment. In addition to this, phosphorous and nitrogen is removed, thereby living up to the rules for special areas in MEPC 227(64). The advanced solution is for those who face the toughest challenges, including cruise ships in protected waters and ship owners with an ambitious environmental agenda.
This system exceeds the strictest IMO regulations.
STP Solupak & STP Solupak HT – GNC Marine
STP Solupak & STP Solupak HT
STP Solupak can help by providing additional nutrients or stabilising factors, ensuring the microbes function optimally and continue to break down wastewater effectively.
This product proactively maintains optimal conditions for the microbes in the bioreactors, restoring and revitalising your system.
Our STP Solupak HT is supplied in 100g soluble sachets, a highly active natural microbial additive designed for start-up, maintenance and toxic shock recovery in biological sewage treatment plants, and marine sanitation devices. The blend of naturally occurring microbes tackles tough organic matter, ensuring high BOD reduction, short hydraulic retention times and low residual sludge.
LA 20 – GNC Marine
LA 20
LA 20 is a unique bio-based descaling product for cleaning and maintenance solution designed for marine and offshore sanitary systems. The product combines an excellent moderately acidic, bio-based cleaning chemistry with scale prevention and scale removal technology.
Key features of LA 20 includes:
- Comprehensive cleaning and sanitation
- Scale prevention and removal
- Environmentally safe and biodegradable
- Effective Antimicrobial Action
- Low-foaming formula
- Material compatibility
ARC 360 – GNC Marine
ARC 360
ARC 360 is an advanced 2-in-1 degreaser and descaling solution designed for marine and offshore environments.
Formulated with bio-based degreasing surfactants and incorporating an effective corrosion inhibitor, ARC 360 can be utilised in manual and cleaning in place (CIP) operations, offering a safer and more effective alternative to conventional acids.
This product improves scale removal, so there is no need for a separate degreaser treatment and is also optimised to protect exposed, cleaning metal surfaces, welds and joints.
Key features of ARC 360 includes:
- 2-in-1 cleaning and descaling
- Enhanced corrosion protection
- Environmentally safe
- Superior performance
- Non-abrasive & Material-friendly
We have a solution for any challenge
Navies
We have the needed approvals and live up to all requirements in order to deliver to navies around the world.
Offshore
Our systems can be delivered with all special features required offshore e.g. EEX/ATEX approvals.
Passenger vessels
We have systems that live up to and exceed the strictest requirements from IMO including those for passenger vessels and special areas.
Retrofit
We are experienced in custom building bioreactors and fit them into even the tightest spaces on existing vessels.
We can deliver auxiliary solutions or connect with existing systems
Grease separating units
A well dimensioned grease separation is essential for a well functioning water treatment system for both black and grey water. Besides reducing the organic load of the treatment plant, it also prevents grease from building up in the vessel tanks and piping.
Vacuum collection solutions
The majority of our treatment systems are delivered with a G&O vacuum collection integrated into the system control and structure.
Sludge handling solutions
Sludge handling procedures will become a requirement in future marine regulations. We can dewater the sludge to minimise the volume of tanks required for storing sludge, returning water to the sewage treatment plant for processing before discharge.
Sludge can be incinerated or disposed as solid waste.
Customer case
A2SEA Challengers story
Off the mainland coast, an offshore construction vessel, A2SEA’s Sea Challenger, found itself to have met the capacity of its biological sewage treatment plant. A four-month project caused an increase in personnel on board the vessel and meant a quick solution for waste water treatment was needed.
