Marine sanitation products for ships and vessels
Biological treatments and cleaners for marine sanitation systems on ships, tankers and offshore vessels.
Why marine sanitation systems need specialist support
Onboard sanitation systems handle continuous waste streams under strict discharge regulations - and small disruptions can quickly become big problems.
Variation in load, temperature, chemistry and flow can all upset biological treatment, leading to odours, blockages, sludge build-up and reduced efficiency in sewage treatment plants and holding tanks.
Biotal Marine sanitation products are formulated to stabilise and support these systems over time. Using application-specific bacteria and eco-benign® chemistry, our treatments help maintain biological activity, improve waste breakdown, and reduce the build-up of solids and scale across black water, grey water and vacuum systems.
Rather than short-term chemical intervention, our marine sanitation range is designed to keep systems operating as intended - improving consistency, reducing maintenance demand, and supporting compliant discharge under MARPOL Annex IV.
Built for biological stability and discharge compliance
The problem
Sanitation systems disrupt easily
Variation in load, chemicals, temperature and flow can all upset biological treatment in marine sewage treatment plants (MSDs). When the biology destabilises, odours and blockages follow quickly, sludge builds up in holding tanks, and discharge can fall outside MARPOL Annex IV limits - putting compliance at risk during port state inspection.
The Biotal approach
Biology that stabilises the system
Biotal Marine sanitation products use application-specific bacterial strains that maintain biological activity across black water, grey water and vacuum systems. Rather than reactive chemical intervention, our treatments support the system continuously.
The result
Compliant discharge, fewer failures
Stable MSD performance, reduced sludge accumulation in holding tanks, fewer odour complaints, and discharge that stays within MARPOL Annex IV limits - even under variable load.

Our environmentally responsible formulations are award-winning
Sustainability matters
Not all bacteria are equal
We select specific bacterial strains for each application, focusing on performance and environmental compatibility rather than generic biology.
Fermented & processed in our own facility
Producing our biology in-house gives us full control over quality, consistency and environmental standards at every stage.
Scientifically validated, verified strains
Each strain is researched, tested and proven for its intended use, ensuring reliable performance without unnecessary environmental impact.
Gentle on marine life and underwater environments
Our formulations are designed to minimise toxicity beyond oil reduction alone, helping protect marine life and support healthier underwater ecosystems.
