Global water scarcity necessitates the reuse of domestic, agricultural and industrial wastewaters. To achieve this objective, in many cases advanced treatment concepts are required, in which biological treatment processes for removal and recovery of bulk contaminants are supported by physical-chemical treatment methods for removal of trace and/or non-biodegradable contaminants. In this course, the emphasis is on these physical-chemical unit operations and technology trains for drinking water purification and micropollutants removal from water. Membrane treatment and advanced oxidation processes are some examples of the unit operations. This course deals with the background knowledge required for reactor design, optimization of reactor performance and scaling up. This includes physical transport phenomena, chemical and physical equilibria, chemical reaction kinetics, phase separation, and biological processes. A number of realistic cases are described, which illustrate how, based on wastewater characteristics and effluent requirements, the appropriate unit processes can be selected and designed.
Learning outcomes:
After successful completion of this course students are expected to be able to:
- apply the principles of diffusion and mass transfer for modeling and design of separation processes;
- model coupling of mass transfer, mass diffusion and chemical or biological reactions for reactor design;
- integrate this knowledge for complex integrated design calculations;
- evaluate a broad range of advanced water treatment technologies for application in water reuse systems;
- evaluate water quality with respect to chemical and biological safety for use in drinking water applications;
- select and design drinking water technology trains for water purification.
