OxyMem - Membrane Aerated Biofilm Reactor (MABR)

OxyMem simply solves OPEX intensive wastewater treatment with smarter aeration

The OxyMem Membrane Aerated Biofilm Reactor (MABR) is deployed as a modular cage design which can be fitted directly into an existing aeration tank. The OxyMem MABR combines  biological treatment for carbon and nitrogen removal  which brings effluent to required discharge standards, all incorporated into a compact structure.

Biological treatment  is accomplished through an attached growth system supported by an array of hollow fibre membranes. The MABR habitat creates an ideal environment to support a robust biofilm which absorbs and consumes carbon and nitrogen based pollutants. This offers improved nutrient removal, energy efficiency and impressive process resilience in a reduced footprint. The typical caged unit for municipal and industrial use is sized for an oxygen delivery capacity of 25kg of O2 / day when operating on air. OxyMem can also operate on Oxygen – 100kg /day.

How does it work?

Following primary treatment the influent travels through the OxyMem MABR and in doing so the  nutrient content is consumed by biofilm  that is attached to the membranes. The MABR uses hollow fibre, gas permeable membranes, to support the fixed film ecosystem for the biology which allows for direct delivery of oxygen to the micro-organisms. MABR can achieve 95% oxygen transfer rates which results in superior energy (75% saving) and process (8kgO2/ kWh) performance.

The MABR combines biological treatment for carbon and nitrogen removal which brings effluent to required discharge standards, all incorporated into a compact ‘drop in’ structure. Biological treatment is accomplished through an attached growth system supported by an array of hollow fibre membranes. The MABR habitat creates an ideal environment to support a robust biofilm which absorbs and consumes carbon and nitrogen based pollutants. This offers improved nutrient removal, energy efficiency and impressive process resilience in a reduced footprint.

What are the benefits?

• The oxygen transfer efficiency per unit of energy is 8kg O2/kWh compared to 1-2kg O2/kWh achieved from fine bubble in a conventional activated sludge process.
• The energy consumption of the system is 0.25 kWh/kg COD removed, which provides approximately 4X reduction in the energy of fine bubble diffusion used in activated sludge.
• 50% less sludge production compared to conventional activated sludge.
• OxyMem’s highly automated process significantly reduces operator support time.
• OxyMem can achieve all of this in a greatly reduced footprint.
