Black and Grey Water Systems

Keeping black and grey water systems performing cleanly and consistently.


Managing black and grey water on board vessels has become increasingly complex as regulatory requirements continue to evolve.

Storage, collection and treatment systems are expected to perform reliably while avoiding odours, blockages, corrosion and downstream compliance issues.

Our black and grey water solutions are designed to support these systems in day-to-day operation. Using application-specific biology and eco-benign® chemistry, they help break down organic waste, fats and build-up at source, reducing the need for aggressive or incompatible chemical treatments.

By working with sewage and waste water systems rather than against them, our products support consistent performance over time and help avoid the cycle of reactive maintenance and short-term fixes.

Where our solutions are used

Grey water storage tanks and associated pipework

Black water collection and holding systems

Sewage treatment plants and transfer lines

Galley, accommodation and laundry waste systems

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.

Proud to work with industry leaders
