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
Continuous assessment: Theory tests. The assessment of chapters I, II and III will be carried out through three written tests with a total score of 13 points.
The assessment of chapters IV and V will be carried out through a written test with a total score of 7 points. Students whose sum of two marks exceeds or equals 10 points and who have a minimum of 6 points in relation to chapters I, II and II and 3 points in relation to chapters IV and V are exempt from the exam.
Exam assessment: During exam or appeal periods, students will be able to take only one written test that weighs the same as the continuous assessment and the minimum mark for approval is 10.

Teaching Method
In theoretical classes, students learn about the different types of effluent treatment, putting into practice the fundamental knowledge through the resolution of exercises and equipment design.
