| Resumo: | New technologies and processes have been developed, searching for higher efficiency to improve the treatment of effluents discharged into the environment. This work presents the performances, advantages, and disadvantages of two of these processes, the MBR (Membrane Bioreactor) and the MABR (Membrane-Aerated Biofilm Reactor), considering that there is not enough literature available for MABR design and for comparing both processes when is needed to choose one of it. To run the experimental study, a 1.2 m3/d MABR pilot plant was installed in parallel with a MBR full-scale sewage treatment plant, in the same place, using the same raw sewage source. The results presented that the MBR had higher removal efficiencies for Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Total Suspended Solids (TSS) and Total Phosphorus (TP). For Total Kjeldahl Nitrogen (TKN), both processes obtained similar values. However, the MABR was more efficient concerning the indicators of energy consumption and COD and TKN load removed per reactor volume. In addition, it was verified the total suspended solids had an essential impact on the performance of the MABR, concluding that it is necessary to have an efficient system to control and remove the TSS from the reactor as well one separation downstream step such as a filtration or sedimentation system. |
