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.
