Conventional technologies have clear limitations in the treatment of wastewater with high concentrations of FOG (Fats, Oils and Greases) and high levels of COD (Chemical Oxygen Demand) or solids.
Especially the variation in wastewater strength and composition has traditionally been a major cause of unstable systems, whether the processes were physical, chemical, or biological in nature.
The aerobic membrane bioreactor (MBR) does a remarkably good job in producing clean and directly reusable water, even if close monitoring has to be taken for granted in most older systems.
The aerobic MBR uses biological treatment with microorganisms that flourish in the presence of oxygen. The aerobic reactor is a basin in which bacteria feed and multiply on the nutrients in the wastewater. Blowers aerate the basin continuously to provide enough oxygen.
