Class Chemical and Biological Reactors

This CU is mandatory in the course curriculum and aims to introduce the concepts of dimensioning, functioning and operationalization of chemical and biological reactors.

Not applicable

1. Stoichiometry. Kinetics of chemical and microbiological reactions. Microbial growth. Yield. Mass and energy balance. 2. Reactors. Types of ideal reactors. Characteristic equations and mass and energy balances. Characterization and operation. Scale effect. Residence time. 3. Single-phase discontinuous reactors. Tubular continuous reactors. Perfectly stirred continuous reactors. Comparison of different types of reactors and selection. 4. Use of different types of biological reactors in environmental processes. Applications. 5. Mass transfer and biological reaction. Dimensioning of some types of biological reactors. Activated sludge. Anaerobic digesters. Fixed biomass reactors.

This CU will use some active methodologies that promote greater student involvement in pedagogical activities, such as Flipped Classroom. This methodology will be used in the most practical and laboratory aspects, carried out in a collaborative environment (in groups) and always with peer assessment and self-assessment. Although laboratory work is not an innovative methodology, it is considered important to mention here since carrying it out helps in the consolidation of theoretical contents and in the students' involvement. In terms of digital technologies, the following will be used: moodle; data analysis (Excel or SPSS); Google Forms.
