DEYUAN MARINE Launches Domestic Sewage Treatment System for Ships, Empowering Green and Compliant Voyages with Cutting-edge Technologies
Publish Time: 2026-04-09 Origin: Site
DEYUAN MARINE has launched a marine domestic sewage treatment system, designed and manufactured in strict accordance with international maritime standards. The system has obtained authoritative certifications from multiple classification societies and is supported by mature supporting technologies, enabling highly efficient and compliant treatment of shipboard domestic sewage. It provides reliable equipment support for the green development of the shipping industry and fully meets the environmental operation requirements of ocean-going vessels.
Built to International Standards for Full Compliance
Developed in accordance with the latest IMO resolution MEPC.227(64), the system has passed certifications from IACS member classification societies including CCS, ABS, LR, BV and DNV.GL, fully complying with the provisions of MARPOL Annex IV. It is the standard choice for ocean-going vessels of 400 gross tonnage and above.
Adopting an integrated biological treatment + ultrafiltration process, the system can simultaneously treat both black water and grey water from ships. The treated effluent quality precisely meets international discharge standards, technically ensuring full compliance of ship sewage discharge.
Highly Adaptive Design for Outstanding Practicality
With a rated treatment capacity covering 10–400 persons, the system adapts to vessels of various tonnages and passenger capacities, and can also be extended to onshore sewage treatment applications. It supports dual power specifications of 380V/50Hz or 440V/60Hz, matching power standards across different regions worldwide.
In addition, the system features an asbestos-free design and holds the official marine product certification from China Classification Society (CCS), meeting the safety and environmental requirements of marine equipment while standardizing daily maintenance.
Supported by Supporting Technologies for More Efficient Operation and Maintenance
The system is equipped with the mature technical system of the HBNA Series domestic sewage treatment units. Its composite process of oxidative degradation + microfiltration + physical disinfection, combined with MBR membrane separation and UV disinfection, ensures that key effluent indicators such as COD and BOD₅ far exceed industrial standards. The equipment is compact in size and structure, with no secondary pollution.
The fully automatic electric control system of HBNA supporting technology supports manual/auto dual-mode operation and is equipped with remote signal output. The standardized systems for sludge cultivation and acclimation, MBR membrane module chemical cleaning, and troubleshooting greatly reduce equipment operation difficulty and later-stage operation and maintenance costs.
With international compliance as the core, adaptability and practicality as the foundation, and efficient operation and maintenance as the guarantee, DEYUAN MARINE’s marine domestic sewage treatment system, integrated with HBNA’s professional supporting technologies, forms a one-stop ship sewage treatment solution. It injects robust impetus into ocean-going vessels to uphold environmental protection concepts, achieve compliant voyages, and drive the environmental upgrading of the shipping industry.
