Pure MABR Biofilm Module with a High Rate Treatment Capacity of 25kg of COD per day.

Membrane Aerated Biofilm Reactor Explained

OxyFILM is a pure biofilm (fixed film) system which allows for aeration from the carrier side. It exploits a gas permeable hollow fibre membrane which allows the bacteria to ‘breath’ by allowing the oxygen to travel across the non porous wall by way of diffusion. 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 incredibily energy efficient.

Key Benefits INCLUDE


1. Easy to Install

OxyMem MABR can easily be installed on site within a short time (hours), and with minimal effort. It can also be installed quickly into a biological process tank on site e.g. it could hang from a wall or suitable structure so that the top of is just above top water level. Once in position, the membrane cartridge is simply connected up to a small air blower and its power is turned on.

2. High Energy Efficiency

Oxygen transfer efficiency per unit of energy is 14kg O2/kWh. 7X more efficient than Conventional Activated Sludge (CAS) and 15X more energy efficient than Moving Bed BioReactor (MBBR). Energy consumption for Industrial applications is typically 0.125 kWh per kg of COD removed. Energy consumption for typical Municipal wastewater treatment is in the order of 0.1 – 0.2 kWh per m³ of wastewater treated.    

3. Low Sludge Production

50% lower sludge production compared to CAS. Biofilm delivers a much lower sludge yield, 0.1-0.15kgTSS/kg COD removed because more of the COD is oxidised to CO2.
