  • Bubble Aeration Efficiency
  • Membrane Aeration Efficiency
  • How much oxygen can be delivered
  • How oxygen transfer is maintained to prevent the system turning anaerobic

OxyFas - Integrated Activated Sludge Data Sheet

How OxyMem's MABR Can Transform Your Wastewater Plant


The Membrane Aerated Biofilm Reactor is a game changer for wastewater treatment. Understand how to apply the MABR to reduce OPEX intensive biological treatment with smarter aeration. You will learn: 

  • The Historical Context
  • Anaerobic Conversion
  • Aerobic Conversion
  • Introduction to MABR
  • The MABR Process
  • Key Benefits of MABR

IFAS MABR Solutions


As plants move towards the end of their working life it often means wastewater is not being treated to the required discharge levels. These installations are operating well beyond their intended lifespan and beyond their intended capacity. These issues all contribute to an inefficient and unsustainable demand for energy. The MABR can be deployed in a matter of days to supplement the biological treatment capacity of an existing Activated Sludge process and increase the treatment capacity by 50% allowing for either treatment capacity or higher effluent quality.

Mini MABR for testing


OxyTube provides end users with an opportunity to experience advanced Membrane Aerated Biofilm Reactor (MABR) technology first hand, on your own wastewater facility, with minimal investment. The robust, high quality stainless steel tube is 20cm in diameter and just 120cm in length. As a result, it can easily be dropped into a biological tank on your facility.

Efficient Wastewater Treatment


Wastewater treatment is a process used to convert wastewater into an effluent (out-flowing of water to a receiving body of water) that can then be returned to the water cycle, with minimal impact on the environment, or can be directly reused. However, a global estimate by UNDP and UN-Habitat is that 90% of all wastewater generated is released into the environment untreated. In many developing countries the bulk of domestic and industrial wastewater is discharged without any treatment or after primary treatment only. .

Who Invented MABR?


We continue to be amazed by the number of companies that attempt to take credit for the invention of the Membrane Aerated Biofilm Reactor. You would think that for something that has only recently come to market (2013) that it would be easy to confirm who was responsible, but the reality is the concept has been around for a very long time. This is also one of the reasons that MABR patents are challenging to find as most of them have expired.

  • Optimized membrane volume

  • Simple deployment

What is MABR? Membrane Aerated Biofilm Reactor Explained


The MABR habitat creates an ideal environment to support a very resilient biofilm that can withstand hydraulic shock loads and process upsets. The biofilm absorbs and consumes carbon and nitrogen based pollutants, but unlike conventional fixed film/biofilm systems (MBBR, RBC) it is incredibility energy efficient.
