Most wastewater plants waste energy fighting physics. MABR works with it.
Traditional aeration blows bubbles through water a brute-force approach that squanders up to 90% of the oxygen before bacteria ever use it. MABR technology takes a fundamentally different route.
A spirally wound, semi-permeable membrane delivers oxygen directly to a biofilm growing on its surface molecule by molecule, precisely where the bacteria need it. Oxygen transfer efficiency exceeds 90%, compared to 10–20% for conventional diffused aeration. The energy savings are not marginal. They are transformational.
One tank. Two processes. Zero compromise.
Conventional treatment plants require separate aerobic and anoxic environments dedicated tanks, additional pumping, more real estate just to complete the nitrogen cycle. The MABR achieves simultaneous nitrification and denitrification (SND) within a single vessel.
Here’s why: the biofilm on the membrane surface is oxygen-saturated, driving nitrification. Just millimeters away, the bulk liquid remains anoxic, completing denitrification. No additional carbon dosing. No inter-stage recirculation. No extra tankage.
The result: total nitrogen removal in a footprint up to 50% smaller than conventional activated sludge systems while meeting effluent standards as stringent as South Africa’s Special Limits (COD < 30 mg/L, NH₄-N < 2 mg/L, NO₃ < 11 mg/L).
Built for where infrastructure is hardest.
The Aspiral™ by Fluence units are pre-assembled, containerized, and plug-and-play ready. They can be deployed in weeks, not years, no civil works, no large concrete structures, no specialist construction crews on-site. Capacity scales modularly, so a system serving 500 people today can be expanded to serve 5,000 tomorrow without redesign.
For municipalities, mines, industrial operators, and developers across Sub-Saharan Africa and the Middle East, this changes the calculus entirely. High-performance treatment is no longer the exclusive domain of cities with deep infrastructure budgets.
MEB Energy: the integrator that makes it work.
MEB doesn’t just supply equipment we engineer complete water and wastewater solutions around it. From feasibility and process design through to commissioning and operator training, our teams have deployed MABR-based systems in some of the most demanding environments on the continent.
If your operation generates wastewater that needs to meet compliance, protect a water source, or enable reuse MABR is worth a serious look.
