Passenger Vessels
Advanced Wastewater Treatment for Demanding Regulations
Passenger vessels face some of the strictest wastewater treatment requirements in the maritime industry, particularly when operating in Special Areas like the Baltic Sea, governed under IMO MEPC 227(64), section 4.2. At G&O Bioreactors, we deliver advanced membrane systems engineered to meet and exceed these standards.
IMO & Special Area Compliance
Since 2016, regulations have required effective removal of nutrients like phosphorus and nitrogen to prevent environmental damage. G&O was among the first to obtain approvals under these tightened rules, and we continue to adapt as more areas adopt similar requirements.
Tailored Systems for Passenger Operations
Our solutions are specifically engineered for the unique challenges of passenger vessels:
- Flexible integration: We work closely with ship designers and owners to minimise installation footprints.
- Smart tank solutions: Our systems can be built directly into the vessel’s structural tanks, reducing the need for additional engine room space.
- Global approvals: Units are approved for Transport Canada and Chilean Navy requirement as well as fully compliant with the effluent demands of US Coast Guard for type 1 +2 + Alaska regulation.
Compatibility Without Compromise
We frequently meet concerns about system compatibility. It’s a common misconception that collection systems (e.g., toilets and vacuum systems) must come from the same provider as the treatment plant. In reality, G&O systems are designed to interface with any brand of collection system.
For those seeking a more complete setup, G&O can also supply integrated grease separation and intermediate pump tanks, ensuring reliable downstream flow to the treatment plant.
Unlike many wastewater treatment systems, G&O Bioreactors operate without the need for chemical dosing or complex PLC control systems. This not only simplifies the installation process but also significantly reduces commissioning efforts and ongoing maintenance requirements. By eliminating chlorine-based disinfection, our systems minimise both environmental risk and operational disruptions, ensuring more stable uptime, fewer alarms, and easier handling for the crew.
Our membrane systems offer a robust and future-proof solution to wastewater compliance – without the need for unnecessary system overhauls.
