text: While the AnMBR technology has many benefits for revolutionizing wastewater treatment, it does not come without its drawbacks. The AnMBR is prone to membrane fouling by aggregation of bacteria. This proves to be quite dangerous for the technology as it would drastically reduce the efficiency of filtration, in turn also increasing energy consumption, making the entire process more expensive. Membrane fouling also leads to the technology having to be replaced much more often, which is also expensive. In addition, the anaerobic bacteria are susceptible to entering the effluent, which leads to their loss in the reactor unit.
