Problem
Recreational vessels must treat onboard blackwater to comply with the Dutch lozingswet and avoid fines, but traditional solutions rely on bulky pump stations, complex installations, and regular maintenance, limiting operational flexibility and contributing to water pollution.
Solution
Fluss delivers the FlussGuard, a patented, fully certified blackwater treatment unit designed for marine applications. The compact all‑in‑one system automatically disinfects toilet waste to meet RLBI, CE and ISO 8099‑2 standards, allowing legal over‑board discharge without external pump stations. Installation is plug‑and‑play: the unit mounts to the deck, connects to existing waste lines via swivel hose fittings, and draws power from a standard 230 V source. Operators select a low (7.5 L/h) or high (15 L/h) power mode, or optionally link to the engine’s coolant circuit for up to 40 L/h with minimal electricity use. The silent, filter‑free cycle requires no consumables, and the integrated pump and heating element ensure consistent pathogen reduction. Compliance documentation is provided for inspections, eliminating the risk of €2 000 penalties and supporting environmentally responsible boating.
Target Audience
Primary customers are owners of motor yachts, sailing yachts, houseboats and other pleasure vessels that need a compact, compliant blackwater solution, as well as marine service dealers installing and maintaining such systems.
