This optional subject allows students to implement and improve the theoretical concepts acquired within the subjects of the environmental orientation that run before (Environmental Engineering and Water Management and Treatment) and in parallel (Air Pollution Prevention and Treatment).
Its overall objective is therefore to gain an academic-technical training, at small-scale lab and pilot plant level, in the management and operation of treatment systems used in liquid and air streams. By doing so, students will become familiar with equipments and processes that may be found in their future career, and at the same time an specific focus will be paid on safety issues and sustainability.
The course consists of a set of experiments where pilot plants and lab units are operated with relation to treatment technologies, both physical-chemical and biological, more common for liquid and air effluents. The program is divided in two main sections:
Section I. Wastewater Treatment
1.- Aerobic wastewater treatment plant at laboratory scale.
2.- Studies of settling for settlers and thickeners design.
3.- Sludge flotation treatment.
4 .- Coagulation-flocculation assays: Jar-test.
5.- Removal of dyes with fenton reagent
6.- Removal of dyes with ozone
Section II. Treatment of air streams and acoustic pollution
7 .- Solid removal from gaseous streams
8.- Environmental noise maping
Specific aims (per section): The contents of each experiment are described below as the aims of each one.
Section I. Wastewater Treatment
In the activated sludge system, two parameters with importance on operation and design will be analysed: oxygen consumption rate and volumetric mass transfer coefficient. Also a mass balance will be developed to confirm the oxygen consumption rate previously determined. This type of reactor will be analysed based on several parameters (pH, dissolved oxygen, etc).
The students will study, based on settling characteristics of several materials (sand, biological and chemical sludge) the design of desanders, settlers and thickeners. The experimental data allow them the scale-up of slid-liquid units to be used in wastewater plants.
An example of the units used to the separation of low-density solids is the flotation units using dispersed or dissolved air. In this type of experiment the use of dissolved air will be used by the previous saturation of the liquid phase at different pressures producing the clarification of the water and obtaining a thickening sludge.
To complete the studies on settling, several experiments on coagulation-flocculation will be carried out to obtain an optimized settling of solids in the wastewater by the addition of coagulants or flocculants. The main aim of this work is to study the procedure to produce the coagulation using different substances (organic or inorganic) optimizing the amount and pH. An economic analysis will be also performed as an additional criterion.
The Fenton process will be used to treat effluents that involve the presence of industrial dyes to remove the colour. The optimal conditions regard pH, Fe2+ amount and H2O2 amount will be obtained. Under these conditions the overall kinetics will be determined.
Also ozone as oxidizing agent will be used to treat wastewater from textile industry. Several tests will be carried out to obtain the colour removal rate and estimate the possible implementation of this type of technique.
Section II. Treatment of air streams and acoustic pollution
Suspended solids in gas phases will be removed and the influence of main parameters (operation variables and solids characteristics) will be analysed on the basis efficiency of each type of separator. The gas flowrate and solids concentration will be the variables to be studied. Also the influence of size and density of solids will be additional studies. The efficiency of separation will be determined based on solids concentration in each part by filtration.
A sound level meter will be used to carry out a noise map. These experiments consist in determination of noise indices and specially the noise caused by the traffic in previously defined zones proposing different improving measurements.

In this course the student will acquire or perform a series of general skills, desirable in any university degree, and a series of specific characteristics linked to Chemical Engineering. Within the framework of competencies that are designed for certification, students will be instructed in the following competencies:
Generals
CG7 –Analyze the social and environmental impact
Transversals:
CT4 –Use and development of informatics applications.
CT6 –Problems resolution
CT7 –Take decisions
CT8 –Teamwork
CT13 –Apply the knowledge to the practice
CT14 –Adaptation to new situations
CT16 –Sensibility to environmental fields
Specifics
CI10 –Basic and applied knowledge to environmental technologies and sustainability
SCENARIO 1:
At the beginning of each group, an overview of the subject will be given by focusing on the objectives to be achieved, the different types of experiments available and how the student must face them and the final lab report. Afterwards, students receive information about the safety rules, which must be read and followed.
Students will be distributed in working groups of 3 people (max). Each group is expected to perform a total of 4 experiments.
Virtual campus (Moodle) and MS TEAMS will be used for communication; using the virtual campus for providing de manuals and all the complementary information of interest.
SCENARIO 2:
Will run as scenario 1.
SCENARIO 3:
The hours of laboratory practices will be replaced by presentations, videos and / or MS Teams and calculations with data supplied by the teacher previously obtained with the same equipment under study. Teaching will be therefore virtual and synchronism (MS Teams).
Table 1 shows the evaluation of competences corresponding to each activity to be carried out.

The evaluation of the performance of each student will take into account three different aspects: i) attitude and laboratory work, ii) quality of the final lab report, and iii) oral presentation and defence, where both quality and clarity of the presentation as well as the capacity to answer the questions done by professors will be evaluated.
The student's grade will be a weighted average of the three elements. To pass the subject a minimum performance of 30% is required in all of them.
If the student failed at the 1st opportunity and having done the experiments, the 2nd opportunity will imply a final test.
Attendance is compulsory in the three scenarios, so any person not attending to more than 20% of the hours will get a FAIL.
Next table indicates the competences evaluation planning in each activity.

The weight of each item in the final will depend on the scenario:
# Scenarios 1 and 2 – FACE-TO-FACE EVALUATION: Attitude and laboratory work (30%), quality of the final lab report (30%) and oral presentation and defence (40%).
# Scenario 3 – VIRTUAL EVALUATION (Virtual campus and/or TEAMS): Proactive following (10%), quality of the final lab report (40%) and oral presentation and defence (50%).
In cases of fraudulent performance of exercises or probes, the provisions of the Regulations for evaluating student academic performance and reviewing grades will apply.
The course has a workload of 4,5 ECTS (European Credit Transfer System). Each ECTS credit corresponds to 25 hours of total work. For this particular course, the credits are allocated as follows:
Activity····················Face-to-face hours·············Factor············Personal work·········· TOTAL
Laboratory··························38···························1,5·····················57······················95

TOTAL································42··························· - ······················70,5···················112,5
Face-to-face hours represent the number of hours of classroom material through the various activities carried out. The factor indicates the estimated hours the student has to dedicate to each hour of activity. Personal work hours are obtained by multiplying the two previous elements and represents the total workload involved in each activity.
To succeed in this subject, students need math skills (numerical methods for solving equations and statistical analysis of data) and expertise in topics such as wastewater treatment, gas treatment and fluid mechanics.
Microsoft Word and Excel competence and familiarity in the use of a simulation program is also advisable. A basic level of English in the Spanish/Galician group to make easier the use of books, scientific papers and web sites. For the English group the language requirements stablished in the LEDUS regulation will be apply.
Subject will be taught in English (GROUP 1) and Spanish/Galician (GROUP 2).
The admission and permanence of the students enrolled in the practical laboratory requires that they know and comply with the standards included in the Protocol of basic training in security matters for experimental spaces of the Higher Technical School of Engineering, available in the security section of their Web.
For the face-to-face teaching, the mask must be used during the student's stay in the Centre. Follow scrupulously all the indications of the health authorities and of the USC itself, for the protection of the health of the Covid-19. Wear a mask, apply a hydrogel or wash your hands with soap and water following the instructions, and when possible increase the distance with the rest of the classmates and professors.
For telematic teaching:
• It is necessary to have a computer with a microphone and a camera to carry out the telematic activities scheduled throughout the course.
• Improve information and digital skills with the resources available at USC.
