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.

Learning outcomes and competences

LEARNING OUTCOMES. The students will be able to acquire:
• knowledge in methodologies for environmental quality monitoring and in the domain of wastewater and residues treatment and be capable of using this knowledge for problem formulation, resolution and discussion;
• personal and professional skills and attributes, namely experimentation and knowledge discovery, systemic 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 should attend all the laboratory classes, including those that are protected by the article 4, line) a and b).
- Students have to do all the laboratory assignments and reach a minimum grade of 10 in each module (NP).

Calculation formula of final grade

The final mark (NF) is calculated in accordance with the distribution of classes for each component: Instrumental Methods of Analysis (MIA – lab E105), Environment (AMB – lab E002) and Microbiology (BIO – lab E-105).

NF = 4/14 MIA + 7/14 AMB + 3/14 BIO

MIA = 0.7 NP + 0.3 NT = 0.4 AC + 0.3 NR + 0.3 NT
AMB = 0.7 NP + 0.3 NT = 0.4 AC + 0.3 NR + 0.3 NT
BIO = 0.6 NP + 0.4 NT = 0.6 AC + 0.4 NT

where:
NP - mark of laboratory work, consisting of AC and NR;
AC - mark of the continuous assessment, according to the short-reports, information on the individual laboratory skills, preparation of the experimental work, correct utilization of the laboratory book, active participation in the laboratory tasks and discussion of results;
NR - mark of a complete report done by each group of students (one after the MIA component and another after the AMB component).
NT - mark of written short-tests, with practical and theoretical questions. 3 short-tests will be done, i.e. one after each component: MIA (planned: March 5 - 9), AMB (planned: April 30 - May 4) and BIO (planned: May 28 - June 1), in specific days and place to be scheduled. The minimum NT mark is 7/20.
