Improving by removing. Cleaning both bilge and EGR bleed-off water with effective flocculation technology.
The CD EGR for EGR bleed-off and bilge water offers a streamlined approach to minimize equipment, installation, operational cost and CO2 footprint. While bilge water and EGR bleed-off water fall under different MARPOL Annexes, necessitating segregation, our system ensures they remain separate. This includes distinct holding tanks and sludge tanks. System segregation valves prevent any mixing, including the sludge generated during treatment. The class-approved automated switch-over sequence, managed by system automation, ensures seamless operation. rom the control panel, the operator can effortlessly choose the waste stream for treatment, the recorder or WhiteBox® (optional), oversee, record and segregate the vital discharge parameters, ensuring accurate record-keeping as mandated.
Process description: The CD-unit can take suction from either the EGR bleed-off tank or the Bilge water holding tank. Three three-way valves connected to a selector switch secure that the waste streams are never mixed. The EGR bleed-off water is collected in a bleed-off water drain tank of a cascade type. The tank should be equipped with heating coils to heat the bleed-off water to 40-55 °C, solid sensors that will detect solidification of soot. The system must have segregated sludge tanks as per the Marpol requirements. The wastewater is treated overboard through a WhiteBox® by the CD unit and all vital system data such as tank levels, valve positions, oil content, discharged volume etc. is recorded and logged in the WhiteBox® recorder.

Marinfloc introduces the WTS, engineered for seamless integration with MAN-ES EGR system. Building on two decades of industry experience, we utilize the proven Marinfloc flocculation process to ensure that the WTS not only meets but exceeds operational expectations. Crafted from robust stainless steel, it stands as a testament to durability and precision. To further empower ship crews, we’ve embedded intuitive digital functionalities for streamlined documentation. And for those navigating with MAN-ES engines, the WTS offers the added versatility of doubling as an efficient bilge water separator. A blend of innovation, reliability, and performance – that’s the Marinfloc promise.
MAN-ES EGR Technology: MAN Energy Solutions’ Exhaust Gas Recirculation (EGR) is a proven method to reduce NOx emissions. By reintroducing a portion of the exhaust gas back into the engine, it ensures vessels remain compliant with environmental regulations.
1. Standalone EGR Bleed-off Water Treatment: Specifically designed to treat the bleed-off water from the EGR system, ensuring optimal water quality and regulatory compliance.
2. Combined EGR and Bilge Water Treatment (WTS–>CD-EGR): A dual-purpose solution that integrates wastewater treatment from the EGR system with bilge water separation. This can either be purchased as a combined unit or the standalone WTS can be upgraded to ensure compliance with necessary regulations for bilge water separation.
A Tailored Solution for Modern Vessels: Marinfloc’s WTS for MAN-ES EGR systems provides shipowners with the flexibility to select a solution that best fits their operational requirements, whether it’s standalone wastewater treatment or an integrated approach with the necessary upgrades for bilge water separation.

Marinfloc introduces the WTS, engineered for seamless integration with WinGD iCER system. Building on two decades of industry experience, we utilize the proven Marinfloc flocculation process to ensure that the WTS not only meets but exceeds operational expectations. Crafted from robust stainless steel, it stands as a testament to durability and precision. To further empower ship crews, we’ve embedded intuitive digital functionalities for streamlined documentation. The iCER technology, with its focus on reducing methane slip and fuel consumption, aligns perfectly with Marinfloc’s commitment to sustainability and efficiency.
WinGD’s iCER Technology: The Intelligent Control through Exhaust Recycling (iCER) is WinGD’s innovative solution for their X-DF2.0 engines. This low-pressure recirculation concept is tailored for the X-DF Otto cycle engine technology, offering benefits like reduced fuel consumption, minimized methane slip, and enhanced combustion stability. With the maritime industry moving towards stricter environmental regulations, the iCER technology anticipates future needs, ensuring compliance and sustainability.
Benefits of Integrating WTS with iCER: Marinfloc’s WTS, when integrated with WinGD’s iCER technology, offers a holistic solution for wastewater treatment. The system ensures that the water treated aligns with the environmental benefits of the iCER technology, further reducing the environmental footprint of the vessel. This combined approach ensures that shipowners not only meet regulatory requirements but also contribute significantly to maritime sustainability.
Unlike conventional systems that operate at fixed capacities, the WTS system stands out with its adaptability. It can automatically adjust its overboard discharge capacity in line with water generation, ensuring a consistent supply of treated water to the iCER system. Managed by the Discharge Control Unit tailored for the WIN GD application, this adaptability not only reduces energy consumption and consumable use but also minimizes the CO2 footprint, making it a cost-effective solution for shipowners and operators.

Today’s complex regulatory environment makes it increasingly difficult for crew members to rely on often outdated hard-copy manuals. Failure to have the latest regulations on hand can lead to accidental discharge, which in turn can lead to fines and reputational harm. Ocean Guardian simplifies environmental operations planning, providing key decision making data at your fingertips.
To take care of your continuity we offer 2 options to ensure a cost effective way to keep your OMD unit compliant with the I.M.O. Resolution MEPC.107(49).

The CD unit is a dissolved air flotation and flocculation unit that treats bilge water to below 5 ppm. The technology enables treatment of bilge water of various composition as the operator can adjust the dosage to the current conditions at hand. It was developed onboard ships not simply to fulfil the MARPOL requirements but to meet onboard conditions.
Key benefits
The treatment process
The process can be divided in five stages: Oil separation, Aeration, Flocculation, Flotation and Filtration.
Max capacity 0.25m³ per hour.

The Marinfloc Whitebox® is a failsafe overboard discharge monitoring and control unit. It is installed between the Oily Water Separator (OWS) and the overboard valve. It prevents non-compliant discharge of bilge water and helps to protect the crew from accusations as it presents the evidence of the vessels activities regarding discharge. Apart from logging it also helps prevent illegal discharge from occurring.
All vital discharge data is recorded and linked to the vessel’s GPS; the Whitebox® houses all necessary monitoring and control equipment for the overboard discharge. A digital recorder stores all critical data such as oil content, valve settings, flow via the oil content monitor and overboard flow, door open/closed, vessel position, and time.
The Whitebox can also monitor sewage overboard pump or STP running if connected.The data is stored in a secure digital format in the recorder and the history can be presented on the display or on a separate computer. That enables the crew to present the discharge data to USCG, Vetting, Class or port state and can prove that the operations have been compliant. The data is so detailed that extensive analysis can be made for preventive and performance reports.
The OCEAN GUARDIAN® can be connected to the Whitebox that can close the three way valve in the Whitebox when the vessel passes the 12 nautical mile line anywhere in the world. The Whitebox can also be used to monitor the discharge from the clean drains such as drains from the AC system or air cooler drains from the main engine. This type of water is generally very clean and could be pumped directly overboard which is approved by most classification societies. However as it may contain oil we recommend to discharge it through the Whitebox and if oil is present it will be directed to the bilge water tank for treatment by the OWS. This will greatly reduce the daily bilge water yield and the operation time and running costs of the OWS.
