In conventional biological treatment, bacteria breakdown pollutants in the presence of oxygen which is pumped through diffuses to create bubbles. Most of the oxygen rises to the surface without being used resulting in energy losses.
OxyMem Advantages:
• Simplicity – Media can be installed into new or existing tanks
• Low Energy – Oxygen is delivered at 4X greater energy efficiency
• Drop in Capacity – Increase biomass by up to 50% in a suspended growth system with the ‘Drop in’ attached growth module without the need for additional tanks.
Oxymem's recent recognitions and news:
- EuropaBio shortlisted OxyMem in 2016 for Innovative European Biotech SME Awards,which recognises innovative biotech SMEs and the crucial role they play in answering some of society’s greatest challenges.
- The Dow Chemical Company announced invested in OxyMem Ltd. to accelerate the commercialisation of OxyMem’ s promising wastewater treatment technology – the Membrane Aerated Biofilm Reactor (MABR).
OxyMem's mission is to make OxyMem MABR the mainstream choice for Biological Aeration for Industrial and Municipal Wastewater Plants.
Conventional wastewater treatment consumes 2-3% of a nation’ s electricity production. This is due a 100 years reliance on bubble diffusion for conventional treatment plants which will typically suffer energy losses of 65-70% in the process because of the oxygen transfer limitations in the bubble aeration process.
The Membrane Aerated Biofilm Reactor (MABR) does not have any such limitations. OxyMem MABR does not rely on bubbles to deliver oxygen which makes it 75% more energy efficient.
We are committed to innovation and continuous improvement
OxyMem is recognised as developing the world’s first commercially available Membrane Aerated Biofilm Reactor (MABR). A leading edge technology for the wastewater treatment market.
We are committed to maintaining the level of technical excellence that has been necessary to deliver the first commercial MABR. We will continue to work with our research partners and our customers to advance innovation around this smart aeration solution so as to remain the recognised pioneer of Membrane Aerated Biofilm Reactor.

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.

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.
