Efficient Flocculation for Bilge and EGR Bleed-Off Water
The CD EGR system offers a highly effective solution for cleaning both EGR and Bilge water using advanced flocculation technology. The combined EGR and Bilge Water Treatment system streamlines operations, reducing equipment, installation, operational costs, and the overall CO2 footprint. Despite the different MARPOL Annexes governing bilge water and EGR bleed-off water, the system ensures complete segregation, with separate holding and sludge tanks. System automation, including class-approved segregation valves, prevents any mixing of waste streams and sludge during treatment. From the control panel, operators can effortlessly select the waste stream for treatment, ensuring accurate discharge monitoring, record-keeping, and compliance with MARPOL standards through optional integration with the WhiteBox® system.
Process Overview
The CD unit can handle either EGR bleed-off or bilge water, depending on the selection from a control panel. Three three-way valves, connected to a selector switch, ensure these waste streams never mix. EGR bleed-off water is collected in a cascade-type drain tank, which includes heating coils to maintain a temperature of 40-55°C. Solid sensors in the tank detect soot solidification. Segregated sludge tanks are provided to meet MARPOL requirements. Once processed, wastewater is discharged overboard through a WhiteBox® system, which logs vital data such as tank levels, valve positions, oil content, and discharge volumes, ensuring seamless compliance and traceability.
By integrating bilge and EGR bleed-off water treatment, the CD EGR system ensures operational efficiency while maintaining environmental and regulatory compliance.

Marinfloc Whitebox: Overboard Discharge Monitoring
The Marinfloc Whitebox serves as a failsafe overboard discharge monitoring and control unit. Installed between the Oily Water Separator (OWS) and the overboard valve, it effectively prevents non-compliant discharge of bilge water. Additionally, the Whitebox protects the crew from accusations by presenting evidence of the vessel’s discharge activities. Not only does it log vital data, but it also actively helps prevent illegal discharge.
Comprehensive Data Monitoring
The Whitebox records all essential discharge data and links it to the vessel’s GPS. It houses all necessary monitoring and control equipment for overboard discharge. A digital recorder captures critical information such as oil content, valve settings, flow rates, door status, vessel position, and timestamps.
Moreover, the Whitebox can monitor the sewage overboard pump or Sewage Treatment Plant (STP) if connected. The system stores data in a secure digital format, allowing crews to present discharge data to the USCG, vetting agencies, classification societies, or port state authorities. This comprehensive data set enables detailed analyses for preventive and performance reports.
Furthermore, the OCEAN GUARDIAN® connects to the Whitebox, automatically closing the three-way valve when the vessel crosses the 12-nautical mile line. This feature enhances compliance with international regulations.
Additionally, the Whitebox can monitor discharge from clean drains, such as air conditioning systems or engine cooling drains. While this water is generally clean, it may still contain trace oil. Therefore, we recommend routing it through the Whitebox®. If oil is present, the system directs it to the bilge water tank for treatment by the OWS. This approach significantly reduces daily bilge water yield and lowers both operation time and running costs for the OWS. Overall, the Marinfloc Whitebox® provides a comprehensive solution for monitoring and controlling overboard discharge, ensuring compliance and enhancing operational efficiency.
