SWCM-10 Compact Marine Sewage Treatment System for Small Vessels (10-Person Capacity)
The SWCM-10 is a compact, space-efficient marine wastewater treatment plant designed specifically for ships with limited engine room space or those requiring custom configurations. As a modified version of the round SWCM model, it maintains identical technical specifications and performance standards, fully compliant with the latest IMO MARPOL Annex IV 224(67) regulations for marine sewage treatment. This system is ideal for small cruise ships, yachts, fishing vessels, and offshore platforms needing reliable, automated wastewater management solutions.
Custom refitting services are available to meet unique vessel requirements, ensuring seamless integration into existing infrastructure. The SWCM-10 combines advanced MBR (Membrane Bioreactor) technology with innovative design features to optimize performance in confined spaces while delivering superior treatment efficiency.

Frequently Asked Questions (FAQs):
Q1: How does the SWCM-10 comply with marine wastewater regulations?
A: The system meets IMO MARPOL Annex IV 224(67) standards through its advanced MBR treatment process, which effectively removes solids, organic matter, nitrogen, and phosphorus from sewage before discharge.
Q2: What maintenance is required for the membrane system?
A: The SWCM-10 features patented online backflushing technology that automatically cleans the membranes during operation, minimizing manual maintenance. Periodic chemical cleaning may be required every 6-12 months depending on usage.
Q3: Can this system be installed in existing vessels with limited space?
A: Yes, the compact horizontal design and custom refitting options make the SWCM-10 ideal for retrofitting into small engine rooms. Our engineering team can provide installation drawings and support for space-constrained applications.
Q4: What is the power consumption of the SWCM-10?
A: The system requires approximately 1.5kW of power during operation, with energy-efficient components and automatic standby modes to reduce consumption when not in full use.
Q5: How does the air-lift sludge transfer system work?
A: Instead of traditional mechanical pumps, the system uses compressed air to create a lifting effect that transfers sludge between compartments. This approach reduces mechanical complexity, energy consumption, and maintenance requirements while preventing membrane fouling.
Q6: What warranty is provided with the SWCM-10?
A: We offer a 1-year comprehensive warranty covering all components, with extended warranty options available.
Q7: Can the treated water be reused onboard?
A: Yes, with the optional advanced treatment stage, the SWCM-10 can produce effluent suitable for non-potable water reuse applications such as toilet flushing, reducing freshwater consumption onboard by up to 30%.
