A new automated sewage treatment plant solution promises to help operators achieve compliance with MEPC. 227 (64).
De Nora Marine Technologies’ Mariner M64 is a compact, dual-technology marine sewage treatment plant solution (STP) –combining the unique benefits of both electrolytic and biological treatment.
It means vessels with the system can achieve regulatory wastewater compliance with MEPC.227 (64).
“The Mariner M64 unit breaks the historical mould of STP operations and now gives operators, as well as the fishery market, the confidence of using two proven and effective technologies for effective wastewater treatment,” said Dana Casbeer, global product manager, De Nora Marine Technologies.
“It is perfect for vessels where space is a constraint and simple operation is required.”
Clever technology
The Mariner M64 unit features biological treatment through advanced Moving Bed Biofilm Reactor (MBBR) technology with recirculation electrolysis process and reverse polarity – enabling vessel operators to enjoy a small, lightweight unit, which can be easily installed in compact areas.
Combining two opposing technologies, EC and biological, and including an independent, recirculation EC treatment stage prior to discharge allows the Mariner M64 design to function differently from other systems on the market.
Biological treatment on the front end aligned with the recirculation electrolysis through a patent-pending design on the back end prior to discharge, the Mariner M64 unit features an easily maintainable “slider” cell and achieves effective oxidation with lower power consumption – helping to reduce a vessel’s carbon footprint.
The system involves zero chemical dosing for treatment and automatic operation is accomplished with a push of a button. It contains no messy influent sewage screens or filters and is fully automated via a dynamic interface screen – providing continuous, quality discharge of wastewater.
IMO certification of the Mariner M64 technology is expected by the end of 2022.
