The course aims to equip students with (1) a knowledge base on the
major biochemical, physical and physico-chemical processes relevant
to contemporary wastewater treatment; (2) an appreciation of how
these processes in ideal reactors respond to environmental and
operational factors; (3) a knowledge base regarding the
applications and limitations of these biochemical operations; (4)
an ability to construct, use, and interpret mathematical models of
the main biochemical operations; (5) an ability to perform process
design and analysis for the major unit operations, via appropriate
steady-state computations or the use of dynamic process
simulation.
Læringsmål:
En studerende, der fuldt ud har opfyldt kursets mål, vil kunne:
List and discuss the components of wastewater and their
influence on choice of treatment processes.
Describe and contrast the underlying mechanisms of the
different biochemical and physiochemical reactions used in
wastewater treatment.
Size ideal reactors and estimate operational conditions for
steady-state biochemical removal of organic carbon, nitrogen, and
phosphorous from wastewater by use of mass balances, process
kinetics, process stoichiometry, and reactor hydraulics.
Use, compare, contrast, and apply basic design and operational
differences for suspended growth and biofilm bioreactors
Describe and perform basic stoichiometric and sizing
calculations for chemical unit processes in advanced wastewater
treatment.
Describe and perform basic design calculations for various unit
operations applicable to solids or liquid separation.
Sketch and explain complete process trains for treatment of
various wastewaters, recognizing limitations with respect to energy
consumption, operational simplicity, robustness, and
decentralizability.
Develop and use dynamic mass-balance models to describe, size,
and control biochemical processes in various reactor
configurations
Analyze and evaluate full scale treatment plant performance,
and document the results in a professional engineering report.
Perform the conceptual design of a wastewater treatment plant
appropriate to a set of specified effluent or treatment performance
conditions
Describe and discuss in a report format, as well as orally
present selected bioengineering principals and biotechnology
solutions relevant to contemporary wastewater
management.
Kursusindhold:
The course covers process understanding, process modelling, and
design and operation of treatment unit operation processes for the
removal of soluble and particulate organic carbon, nitrogen,
phosphorus, and synthetic organic chemicals from wastewaters.
Special emphasis is given to biochemical processes and physical
separation processes. Chemical treatment processes are covered at
basic level, necessary to understand how they can optimise/enhance
biochemical treatment processes. Conceptual design and analysis of
biological wastewater treatment plants, is the ultimate goal of the
course. Extensive use of simulation models in all phases of the
course is undertaken (no prior programming experience
required).
