Wastewater treatment is essential to ensure the quality of the liquid that will be returned to communities or discharged into the environment. Biological treatments have the purpose of reducing the soluble organic load concentrated in the influent to a confident level through microbiological digestion, this type of treatment can be classified between suspended biomass systems and attached growth systems. MBBR (moving bed biofilm reactor) technology is an adhered growth biological wastewater treatment method where plastic media are introduced into an aeration tank, these media have a specific surface area large enough for the development of biomass. The objective of this research was verifying the efficiency of MBBR technology exposed to real conditions of a wastewater treatment plant with effluents from a mass production food factory. The research required the design of a scale biological reactor and the daily monitoring of critical quality parameters during 165 days of study, as a result, it was proved that the system can guarantee an efficiency greater than 70% in the removal of chemical oxygen demand and a concentration of suspended solids lower than 300 mg/L inside the bioreactor.
