Institut für Apparate- und Umwelttechnik (IAUT)

Objectives (competences):

The student should be able to

  • identify the relevant physical, chemical and biological properties of a wastewater
  • understand the fundamentals of wastewater treatment technologies
  • identify the relevant physical, chemical and biological properties of biosolids from wastewater treatment
  • develop creative solutions for the treatment of wastewater and the control of  emissions to surface water

The course is designed for Master student of “CEE and PSEE” and related courses like UEPT, VT, BSYT and SGA.

Simulation Lab offered for PSEE and SGA master study programmes.

In safety engineering the basic task is to work on indepedent projects in different dimensions. The main goal of this course is the challenge to work independently as an engineer. So you have the task to train yourself in process planing with the process simulation software "ASPEN". For this process you will with support from your team complete different exercises in this course using the e-learning tool. The main task is to write a short document (10 to 12 pages) about a task in process engineering. This task you work on as a group (3 students) and in the document you should describe your work decicions. For example: Which Property package or modell you use and why?

The delivery date for the document and the calculation file as e-mail-appendix is the 31. January 2019. There is no possibility to extend this.

So have fun and good luck

The students gain skills for structuring and writing scientific articles on selected fields of safety or environmental technology. They are able to evaluate published work of other authors and to describe the scientific motivation for their own efforts. They learn appropriate reporting of own scientific achievements and handling of references. Based on the results obtained students are able to derive and express meaningful conclusions.
