30 People Marine Sewage Treatment Plant | MEPC.227(64) & GB3552-2018 Certified
Compact Marine Wastewater Treatment System for Small Vessels
Our 30 people marine sewage treatment plant is an essential MARPOL Annex IV compliant solution for small to mid-sized vessels. This advanced A/O-MBR system combines anaerobic-aerobic biological treatment with membrane filtration to effectively process both black water (toilet waste) and grey water (galley/laundry effluent) while meeting strict IMO and Chinese GB3552-2018 standards.
Key Features & Benefits
✔ Dual Waste Stream Processing – Handles 2.31 m³/day black water + 5.28 m³/day grey water
✔ Advanced A/O-MBR Technology – Micro-electrolysis + membrane bioreactor for superior treatment
✔ Compact Design – 3.6×1.65×1.78m footprint ideal for space-constrained vessels
✔ Global Voltage Compatibility – 220-690V, 50/60Hz operation
✔ Certified Performance – Meets MEPC.227(64) & GB3552-2018 requirements
