Objectives
Manage and operate physical, chemical and biological treatment systems for wastewater treatment plants.
Use specification sheets and manuals for the various treatment organs.
Perform measurements of process variables.
Calculate treatment efficiencies.
Diagnose critical operating situations and propose action measures.
Management of the final destination of the sludge.
Prepare technical operational reports.
Program
I. Introduction to treatment units. Characteristics of a liquid effluent. Pollutant characteristics. Levels of liquid effluent treatment. Global operation of a WWTP.
II. Physical treatment of liquid effluents. Principles and applications of the screening, sifting, sanding, oil and grease removal, flotation, flocculation, sedimentation, decantation and filtration processes.
III. Chemical wastewater treatment processes. Principles and applications of adsorption, ion exchange, disinfection, oxidation, precipitation and membrane processes
IV. Biological wastewater treatment processes. Aerobic processes, activated sludge systems and variants, aerated lagoons, photosynthetic lagoons, percolation filters and discs
biological. Anoxic processes in suspension and in fixed film. Anaerobic processes, anaerobic digesters and anaerobic filters. Natural treatments. Soil and built wetland treatments.
V. Sludge treatment and final destination. Thickening, stabilization, conditioning, dehydration, drying, composting and deposition operations.
Evaluation Methodology
The evaluation will be carried out through the presentation of a work of bibliographic review and application of the knowledge obtained in the course focusing on a theme to be proposed by the responsible teacher.
