Aims :

The course teaches the know of different biological unitary operations for wastewater treatment plants . This course want to give the means for design the plants.

Topics :

Law
Law analysis in force for the design and realization of treatment and drinkable waters plants. Law analysis in force for sludge treatment plants.

Waste water
Project data for waste water treatment plants.

Biological treatments
Attached and suspended growth reactors, kinetics of biological growth. Aerobic and anaerobic processes; theory of processes design.

Design in advanced treatments
Biological nitrogen removal, nitrification, denitrification. Biological phosphorus removal. Combined removal of nitrogen and phosphorus by biological methods.
Removal of nutrients by physical and chemical processes.
MBR processes, Constructed Wetlands.

Simulation models
Simulation model in biological processes: IAWPRC model.
Calculation example for real plants.

Plant design
Phoredox process and its modifications, UCT process and its modification
systems for small communities

Sewage sludge treatment
Biological treatment of sludge. Sludge anaerobic digestion and aerobic stabilization, composting; process theory and design methods.

Practices
Wastewater treatment plant design
