AbstractThis lecture deals with prospective assessments of emerging technologies as well as with the assessment of long-term environmental impact caused by today's activities.
Objective- Understanding prospective environmental assessments, including scenario analysis techniques, prospective emission models, dynamic MFA and LCA.
- Ability to properly plan and conduct prospective environmental assessment studies, for example on emerging technologies or on technical processes that cause long-term environmental impacts.
- Being aware of the uncertainties involved in prospective studies.
- Getting to know measures to prevent long-term emissions or impact in case studies
- Knowing the arguments in favor and against a temporally differentiated weighting of environmental impacts (discounting)
Content- Scenario analysis
- Dynamic material flow analysis
- Temporal differentiation in LCA
- Systems dynamics tools
- Assessment of future and present environmental impact
- Case studies

Process Engineering in Urban Water Management
102-0217-01LProcess Engineering Ib Information
Prerequisite: 102-0217-00L Process Engineering Ia (given in HS).
O3 credits2GE. Morgenroth
AbstractThe purpose of this course is to build on the fundamental understanding of biological processes and wastewater treatment applications that were studied in Process Engineering Ia. Case studies that are jointly discussed in class and student led projects allow you to advance the understanding and critical analysis of biological treatment processes.
ObjectiveStudents should be able to evaluate existing wastewater treatment plants and future designs using basic process understanding, mathematical modeling tools, and knowledge obtained from the current literature. The students shall be capable to apply and recognize the limits of the kinetic models which have been developed to simulate these systems.
ContentAdvanced modeling of activated sludge systems
Nitrification, denitrification, and biological P elimination
Enrichment in mixed culture systems using, e.g., selectors
Biofilm kinetics and application to full scale plants
Critical review of treatment processes
Lecture notesCopies of overheads will be made available.

AbstractAn increasing demand for infrastructure management skills can be observed in the environmental engineering practice. This course gives an introductory overview of infrastructure management skills needed for urban water infrastructures, with a specific focus on pipe deterioration and engineering economics.
ObjectiveAfter successfully finishing the class, the participants will have the following skills and knowledge:
- They can perform basic engineering economic analysis
- Know the typical value and costs involved in running a wastewater infrastructure
- Know the key principles of infrastructure management
- Know how to quantify the future rehabilitation demand
ContentThe nationwide coverage of water distribution and wastewater treatment is one of the major public works achievements in Switzerland and other countries. Annually and per person, 135,000 kg of drinking water is produced and distributed and over 535,000 kg of stormwater and wastewater is drained. These impressive services are done with a pipe network with a length of almost 200,000 km and a total replacement value of 30,000 CHF per capita.

Water services in Switzerland are moving from a phase of new constructions into one of maintenance and optimization. The aim today must be to ensure that existing infrastructure is professionally maintained, to reduce costs, and to ensure the implementation of modern, improved technologies and approaches. These challenging tasks call for sound expertise and professional management.

This course gives an introduction into basic principles of water infrastructure management. The focus is primarily on Switzerland, but most methods and conclusions are valid for many other countries.
