Marine Sewage Treatment System - Triton μ

Sewage Treatment System for Marine / Offshore Applications

Triton μ system is a physicochemical sewage treatment plant, specially designed for treatment of both black (sewage) or the mixture of the back and grey water (wastewater from showers, kitchens, sinks, etc), onboard merchant ships, small yachts and cruise vessels. The system is designed to fulfil requirements of IMO MEPC 159(55) of International Maritime Organisation (IMO) which specifies discharged waste water from sewage treatment plants.

The plant operates in a continuous basis, is fully automatic in normal operation and requires low maintenance.
