The reactors homogeneity can be achieved by applying intensive mixing systems that have high energy consumption. This paper has the aim of determining the optimal system that can assure the close contact while maintaining the energy need as low as possible.WastewaterMicroorganismsBiological reactorsSymposium Proceedings
