Objectives

BACKGROUND
This course consists of structured laboratory classes, where the theoretical concepts are applied in practice, helping to consolidate the knowledge acquired in other courses and develop skills in working in a laboratory environment.

SPECIFIC AIMS
This course aims to provide students consolidation of knowledge acquired in other courses and practical knowledge on various topics relevant to an environmental engineer: principles of instrumental analysis, physicochemical and microbiologic characterization parameters of water and wastewater and unit operations in water and wastewater treatment. It is also intended to develop teamwork and report writing skills.

PREVIOUS KNOWLEDGE
EA0012 Environmental Chemistry II: principles of instrumental analysis
EA0016 Effluents and Residues Characterization
EA0013 Microbiology

PERCENTUAL DISTRIBUTION
Scientific component (establishes and develops scientific bases) – 20%
Technological component (apply to design and process operation) – 80%

LEARNING OUTCOMES
At the end of this course unit students will be able to:
- knowledge in methodologies for monitoring environmental quality in the domain of wastewater and residues and be capable of using problem formulation, resolution and discussion;
- knowledge in methodologies for monitoring environmental quality in the domain of wastewater and residues and be capable of using them in the design of problem solutions and in the forecast and prediction of those problems, including potential counterproductive effects;
- personal and professional skills and attributes, namely experimentation and knowledge discovery, system thinking, personal skills and attitudes and professional skills and attitudes;
- interpersonal skills: teamwork and communication
Conceiving, designing, implementing and operating systems in the enterprise and societal context.

Eligibility for exams

- Students must attend all the laboratory classes, including the ones that are protected by the article 4, line) a and b).
- Students have at do all the lab assignments and reach a minimum grade of 10 in each module.

Calculation formula of final grade

The final grade (NF) is calculated by:
NF =1/2 AMB + 1/4 MIA + 1/4 BIO
in accordance with the number of classes for each component: Environment (AMB – lab E002), Instrumental Methods of Analysis (MIA – lab E105) e Microbiology (BIO – lab E-105).

The final grades of AMB and MIA components are:
AMB = 0,7 NP+0,3 NT = 0,4 AC + 0,3 NR + 0,3 NT and
MIA = 0,7 NP+0,3 NT = 0,4 AC + 0,3 NR + 0,3 NT, where:
-NP – laboratory work evaluation
-AC is the mark of the continuous assessment, which is done by the average of the results and discussion page prepared by the group of students after each laboratory work. The AC grade can be modified (plus or minus 1 point) according to the information on the individual laboratory skills, preparation of the experimental work, correct utilization of the lab exercise book and participation on the discussion of the laboratory work.
-NR is the grade of a complete report done by each student, one after MIA component and other after the AMB component, and chosen between all the component works.
-NT is the grade of written tests, with practical and theoretical questions on of the theme. Tests will be done one after MIA laboratory work and other after AMB laboratory work. The minimum NT grade is 7/20.

The final grade of BIO component is:
BIO = 0.6 AC + 0.4 NT, where:
-AC is the grade of the continuous evaluation, which includes the grade of the report of the laboratory work done by the group of students. The report should be divided in: objective, a scheme of the procedure used (based on the legislation), results, discussion and conclusions of the work. The AC grade can be modified (plus or minus 1 point) according with the information on the individual laboratory skills, preparation of the experimental work, correct utilization of the lab exercise book and participation on the discussion of the laboratory work.
-NT is the grade of a written test, with practical and theoretical questions on of the theme. The test will be done after the laboratory work. The minimum NT grade is 7/20.
