It is an obligatory course under selection and concerns the study of the wastewater disposal system, mainly into water bodies, after their treatment at the biological treatment plant; it also concerns the simulation of flow and diffusion fields of wastewater. The subject matter of the course is to inform students about the basic principles for environmentally sound design of the disposal system without degradation of the aquatic environment.
Upon successful completion of the course the student will have learned:
• the regulations and the basic principles of the operation of the wastewater disposal systems
• the potential environmental impacts by the wastewater disposal and how to deal with them
• to assess the hydraulic and environmental characteristics, to study and design the appropriate disposal system
• to participate in the development of wastewater disposal systems studies and their environmental impacts
• to supervise the study implementation and to evaluate their operation.
Finally, the aim of the course is to acquire basic knowledge and skills so that qualified engineers can use them in their professional careers either as consultants or as contractors of wastewater disposal systems. In particular, at the end of this course the student will further develop the following skills:
• Ability to understand the essential points, concepts and mechanisms related to the design of wastewater disposal systems• Ability to apply methodologies to predict diffusion and dispersion of pollutants in cases of practical problems and wastewater studies, such as through disposal through submarine pipelines
• Ability to study, lifelong learning and continuing professional development
• Ability to design studies of disposal systems, as well as to interdisciplinary cooperation.
