20 Persons Sewage Treatment Equipment

Our cutting-edge 20 Persons Sewage Treatment Equipment is a state-of-the-art pollution prevention system meticulously engineered to meet the rigorous demands of MARPOL Annex IV regulations for small ships, yachts, and marine drilling platforms. This high-efficiency wastewater treatment unit employs an advanced A/O-MBR (Anaerobic-Aerobic Membrane Bioreactor) system, integrating physical separation, micro-electrolysis, and membrane filtration to effectively process up to 1.54 m³/day of black water (toilet waste) and 3.52 m³/day of grey water (galley/laundry/shower drainage), ensuring compliance with IMO MEPC.227(64) and Chinese GB3552-2018 standards for marine sewage discharge.

Key Features & Benefits:

• Dual Waste Stream Processing: Simultaneously treats both black water (toilet waste) and grey water (galley, laundry, shower drainage) for comprehensive wastewater management.
• Advanced A/O-MBR Technology: Combines anaerobic-aerobic treatment with micro-electrolysis and membrane filtration for superior purification performance.
• Compact Marine Design: Features a space-saving footprint of 3.05×1.5×1.3m, making it ideal for small vessels and yachts with limited space.
• Global Voltage Compatibility: Operates efficiently on 220-690V, 50/60Hz power supplies, ensuring worldwide applicability.
• Certified Performance: Meets the strictest international discharge standards, including MARPOL Annex IV, IMO MEPC.227(64), and GB3552-2018, ensuring environmental compliance.
• Versatile Application: Suitable for marine and offshore installations, as well as terrestrial sewage treatment when paired with appropriate pretreatment for grey water.
• Class Society Certifications: Holds certifications from CCS, GL, ABS, DNV, BV, RS, and other leading classification societies, ensuring quality and reliability.

Suitable Applications for 20-Person Marine Sewage Treatment Plant:

This marine sewage treatment system is designed to prevent pollution from ships and marine drilling platforms in accordance with the revised Annex IV of the International Convention for the Prevention of Pollution from Ships (MARPOL 73/78). It effectively treats human body wastes and toilet wastewater (black water) to meet the effluent standards of IMO MEPC.159(55), allowing for safe discharge overboard. The system is also applicable for treating galley and shower drainage (grey water), provided that the grey water is pretreated and a model with sufficient capacity is selected. Additionally, it can be used for terrestrial sewage treatment, achieving national reuse water quality requirements.
