Marine water and waste specialist Hamworthy has unveiled its new Ultra Trident MBR, a membrane bioreactor that brings wastewater treatment to a wider range of vessels.
Hamworthy's first major new system development since becoming independent in June 2026, Ultra Trident represents the latest generation of its MBR technology. Designed to help ships treat black and grey water efficiently and reduce the impact of wastewater discharges on the marine environment, it combines straightforward operation, accessible maintenance and predictable lifecycle costs while requiring less onboard space.
Ultra Trident's compact design allows shipowners and shipyards to specify high-performance biological and membrane treatment where machinery space has previously limited its use. It also reduces the footprint required on larger vessels, freeing valuable space for other onboard systems and functions.
The Ultra Trident range covers treatment capacities from approximately 2 to 200 cubic meters per day. Its flexible configuration makes it suitable for small and mid-sized cruise ships, expedition vessels, ferries, naval and coastguard vessels, research ships, offshore support vessels and merchant ships. The packaged design also supports retrofit projects where machinery space is limited, while multiple units can be installed to provide additional capacity or redundancy.
