Product Description
100 Persons Marine MBR Sewage Treatment System
Product Introduction:
The DY-100 Marine MBR Sewage Treatment System is a compact, high-efficiency wastewater treatment unit specifically designed for marine applications, including vessels, offshore platforms, and island facilities. With a treatment capacity of 7,000 liters per day, this system is rated for 100 persons and delivers effluent quality that fully complies with the latest IMO discharge standards.
Compliance & Certification:
The system meets the requirements of IMO Resolution MEPC.227 (64) – "Revised Guidelines on Implementation of Effluent Standards and Performance Tests for Sewage Treatment Plants". It is type-approved by CCS, with additional certifications available upon request. Each product is supplied with a CCS product certificate.
Effluent Quality (IMO MEPC.227(64) Standards):
The treated effluent from the DY-100 Marine MBR Sewage Treatment System strictly complies with the discharge limits prescribed by IMO Resolution MEPC.227(64). The key parameters are as follows:
*Total Suspended Solids (TSS) – not exceeding 35 mg/L;
*Biochemical Oxygen Demand (BOD₅) – not exceeding 25 mg/L;
*Chemical Oxygen Demand (COD) – not exceeding 125 mg/L;
*Thermotolerant Coliform – not exceeding 100 MPN per 100 mL;
*pH Range – maintained between 6.0 and 8.5;
*Residual Chlorine – not exceeding 0.5 mg/L.

System Composition & Structure:
The DY-100 integrates biological treatment with membrane filtration technology. Its main components include:
1.Main tank (divided into Contact Oxidation Tank 1, Contact Oxidation Tank 2, and MBR membrane tank).
2.Air blower.
3.Crushing pump.
4.Plunger pump.
5.Ultraviolet (UV) sterilizer.
6.Built-in MBR membrane modules.
7.Electric control box.
8.Valves and piping.
All components are mounted on a common steel base frame for easy installation and alignment with the ship's foundation via bolted connections. The system offers both automatic and manual control modes for flexible operation.
Key Features:
*Compact footprint – Space-saving design ideal for confined marine environments.
*High-quality effluent – MBR technology ensures superior solid-liquid separation.
*Reliable disinfection – UV sterilizer provides chemical-free pathogen elimination.
*Corrosion-resistant – Suitable for harsh marine conditions (0–55°C, high humidity).
*Easy maintenance – Modular design with accessible components.
*Global compliance – CCS-certified, meeting international maritime regulations.
Applications:
*Cargo ships and container vessels.
*Passenger ferries and cruise ships.
*Offshore drilling platforms.
*Naval vessels and coast guard ships.
*Remote island facilities.
