20-Persons Marine Sewage Treatment Equipment | MEPC.227(64) & GB3552-2018 Certified
Compact & Efficient Wastewater Solution for Small Vessels
Our 20-persons marine sewage treatment equipment is an essential pollution control system that meets MARPOL Annex IV requirements for small ships and yachts. This advanced A/O-MBR system combines physical separation, anaerobic-aerobic treatment, and membrane filtration to process 1.54 m³/day black water and 3.52 m³/day grey water while exceeding IMO MEPC.227(64) and Chinese GB3552-2018 standards.
Key Features & Benefits
✔ Dual Waste Stream Processing – Handles both black water (toilet waste) and grey water (galley/laundry)
✔ Advanced A/O-MBR Technology – Micro-electrolysis + membrane bioreactor for superior treatment
✔ Compact Marine Design – 3.05×1.5×1.3m footprint ideal for space-limited vessels
✔ Global Voltage Compatibility – 220-690V, 50/60Hz operation
✔ Certified Performance – Meets strictest international discharge standards
