KPP60 Pollution – Energy and Counter–Pollution Technologies



Module code: KPP60


ECTS Credit Points:
20

Module Type:
Compulsory


Year:
1st

Language: Greek

Module general description: The purpose of this module is to educate students on issues related to the human environment, the environmental impact of human activities, the pollution of air, water and soil, the production and consumption of energy, and the management of municipal and industrial wastewaters.

Learning Outcomes:
After completing this module, the student should,
- Be able to describe the energy problem and know the advantages, disadvantages, and environmental consequences of the use of conventional, renewable and alternative energy sources.
- Understand the working principles of the most important technologies for the utilization of renewable energy sources and their applicability in Greece.
- Have knowledge of the major pollutants of air, water and soil, their impact on the environment and human health, and the main anthropogenic activities that are responsible for their production.
- Have knowledge of the international, European and national legal framework related to the protection of the environment.
- Be able to describe and evaluate the most important methods that can be applied for the treatment and disposal of municipal and industrial wastewater streams.
-  Have a basic understanding of the physical, chemical and biological processes that take place in a sewage treatment plant and have the ability to design the basic characteristics of individual units.
- Be able to calculate the characteristics and quantities of sludge produced in wastewater treatment processes and to analyze the methods and technologies that can be applied for the stabilization and dewatering of sludge and the destruction of pathogens.
- Be able to choose the most suitable processes for sludge treatment and disposal, to design the basic characteristics of the project and to select methods for recycling and reuse of useful products, including energy production.

Subjects covered:
1. Ecosystems
2. Energy
3.  Processes  for polution control

Ecosystems-pollution and environmental impacts
Introduction and structure of ecosystems (a short description of ecosystems structure, abiotic and biotic compartments, food chain, energy flow, productivity of ecosystems, biochemical cycles and photosynthesis). Wastes and pollution (atmospheric pollutants, water pollution and contamination, soil pollution, solid wastes, noises). Environmental pollution and impacts to human (introduction to the pollution parameters, toxic wastes and compounds, regulations and directives for environmental protection, environmental quality parameters, risk assessments).

Energy sources and uses

Energy needs and its conventional forms (introduction in energy sources, international energy status and problems, energy categories and sources, production and final forms, environmental impacts, uses and typical consumptions, possibilities and limits of alternative energy sources). Environmental impacts (introduction, air pollutants, wastewaters, solid wastes, secondary pollutants and impacts, clean technologies, greenhouse problem). Orthological use of energy (management of energy sources, energy control and stocks, data analysis, alternative solutions, techno-economic studies for alternative solutions). Energy design (methods for energetic design, thermal recovery, co-production of electricity and thermal energy, replacement of electric and other conventional forms of energy by gas, economic evaluation of energy infrastructure works). Alternative and renewal energy sources (advantages and disadvantages of renewal energy sources, technologies for use of renewal energy sources, sunlight systems, wind energy, photovoltaic systems, biomass, geothermic sources and other renewal sources).

Wastewater treatment plants and sludge disposal
Introduction to the wastewater treatment plants (influence of disposal terms on wastewater treatment plants, water out flow quality, alternative techniques in waste treatment and disposal, quantities and characteristics of wastewaters). Pre-treatment systems (bar racks and grit chambers,). First step-mechanical treatment systems (sedimentation, flotation and first step sludge). Biological treatment systems (activated sludge systems, biological filters, biological disks, biological towers, stabilization lakes, technical wetlands). Phosphorus and nitrogen removal. Advanced methods for wastewater treatment (chemical treatment and advanced oxidative methods). Sterilization of wastes by using ozon and UV light.
Wastewater reuse, (irrigation of agricultural areas, ground water enrichments, industrial recycling, rural reuses). Management of industrial wastewaters and co-treatment with municipal sewage. Sludge treatment and disposal (characteristics of sludge, quantities and volumes of production, safety and storage). Stabilization of sludge (anaerobic digestion, chemical stabilization, water removal, fertilisation, thermal treatment). Final disposal of sludge (agricultural use, soil properties improvement, forestry uses, disposal in landfills). Comparative evaluation of different methods for sludge management and disposal in soil.

Teaching Method: Distance education with five Contact Sessions held at weekends during the academic year

Evaluation: Completion of five written assignments during the academic year, the average grade of which constitute a 30 percent of each student's grade, if a pass is obtained in the final or repetitive examination. Final exam grades constitute a 70 percent of the students' final course grade. More information is available
