Water and Waste Treatment

 

LEARNING RESULTS

The aim of the course is to make students aware of the principles of water resources management, as well as the specific problems they must solve in the areas of treatment and distribution of drinking water, as well as the treatment and sanitation of urban wastewater. Moreover, to experiment in the laboratory in the application of pilot exercises in selected methods of treatment of drinking water and urban wastewater, as well as in the determination of specialized quality parameters and design parameters of treatment units.

After the successful completion of the course the students will be able:

• to contribute to the design, operation supervision and control of the efficiency of surface or groundwater drinking water treatment systems
• to exercise the envisaged control of effective water disinfection of the water supply networks
• to carry out the prescribed procedures for the approval of the suitability of the swimming pools
• to understand the necessity and consolidate the required methodologies and treatment facilities for the disposal of urban wastewater in the Environment
• to have the knowledge necessary to fully exercise the statutory professional rights in the field of Environmental Engineering and in particular of drinking water and wastewater treatment plants, in order to protect Public Health.

 

GENERAL SKILLS

• Autonomous work on issues related to drinking water systems, wastewater systems and swimming pools
• Teamwork to determine parameters of drinking water and wastewater
• Planning and management of water treatment premises, swimming pool water, wastewater treatment facilities
• Decision-making on issues related to the provision of healthy water and the safe disposal of wastewater in soil or in water bodies
• Respect the natural environment through the use of experimental devices for the protection of public health and the environment in general
• Search, analysis and synthesis of data and information, using the necessary technologies and issues related to water (drinking and swimming pools) disinfection and to the treatment, disposal and recycling of wastewater 

 

CORSE CONTENT

Theory

• General aspects of water supply
• Qualitative characteristics of drinking water
• Disinfection of drinking water-control programs in water supply networks
• Sanitary water intake sources protection measures
• Drinking water treatment plants-control function of hygiene
• Wastewater (pollutants-origin)
• Urban waste-qualitative and quantitative characteristics
• Sewerage-Wastewater treatment plans
• Wastewater treatment methods

Laboratory

• Drinking water:

Determination of drinking water quality parameters, with standard laboratory methods and based on the available laboratory equipment.

Experimental investigation procedures:

disinfection with chlorine, aeration, coagulation-sedimentation, filtering water in relation to the available experimental setups laboratory

Familiarity in the use of laboratory equipment, preparation of solutions, use and calibration of measuring instruments, etc.

Case studies of application of those visits to sites / drinking water treatment plants

Analysis of process flow diagrams and quality checks on compliance with health regulations.

• Swimming pools water:

Study of application cases through educational visits to swimming pools

Calculation-sanitary design of water treatment facilities and quality checks on compliance with health regulations.

• Wastewater:

Determination of BOD₅, COD, and other specialized parameters using spectrophotometer and in conjunction with the available laboratory equipment.

Case studies of application processing systems and sewage-sludge disposal through visits to sites / sewage treatment plants and sewage.

Analysis of process flow diagrams, calculation-dimensioning of the emission control devices and disposal systems and quality controls for compliance with health regulations.

Educational visits to units such as Wastewater Treatment Plants, Drinking Water Treatment Plant of EYDAP, Swimming pools

 

STUDENT EVALUATION

Evaluation in Greek language

 

Theory

During the lectures the scope of this course is analyzed. At the end of each lecture the main points are emphasized.

At the end of the semester the evaluation is based 100% on a written final exam that requires short analysis on several topics and occasional problem solving.

Passing mark is 5/10.

 

Laboratory

During the laboratory, students are divided into groups and perform specific laboratory exercises. Before performing the exercise there is an analysis of the theoretical background, presentation of the instruments, utensils, chemicals to be used and the course of the exercise summarized. Students record and present the results.

Also, the laboratory part includes site visits to Wastewater Treatment Plants, Drinking Water Treatment Plant of EYDAP, Swimming pools.

The evaluation of the laboratory part is done by:

Final written exam at the end of the semester (50%)

Interim written reviews after educational visits (30%)

Projects after completion of laboratory exercises (15%)

Daily evaluation during the laboratory exercises (5%)

For the successful completion of the workshop part a weighted average must be at least five (5.0)
