BioFlow for Boats & Yachts
Eco-friendly marine sewage treatment
Marine sewage systems face conditions that household plumbing never does: compact pipework, concentrated organic waste and long periods when the vessel sits unused. The result is often persistent odours and buildup inside the pipes.
BioFlow is designed with nautical sewage systems in mind, giving boat and yacht owners a simple way to support cleaner, better-maintained plumbing.
Whether you look after a private boat, a charter yacht or another marine vessel, BioFlow is added straight through the toilet — no dismantling, no complicated procedure.

The science, simply
How Does BioFlow Work?
BioFlow works with natural enzymes and compounds derived from brown seaweed.
Once poured into the sewage system, these natural components help break down organic matter and dissolve buildup inside the drain pipes.
The result is a cleaner pipe system and fewer unpleasant odours — without relying on aggressive chemical drain cleaners.
