Oxidation processes are a success story in water treatment as they are the first treatment step applied in the early 20th century to provide hygienically safe water. Thereby oxidants such as chlorine, chlorine dioxide or ozone are often applied. However, ongoing research continuously discovers new important insights which can lead to improvement (e.g., degradation of persistent pollutants) but also limitations of oxidation processes (e.g., emerging toxic by-products). To cope with the rapid knowledge gain and to meet the current state of the art, the content of the course will be continuously updated on basis of the latest literature. In brief the course provides:
· A decent insight in the complex processes happening in oxidative water treatment
· skills to choose individual treatment options for a specific water resources
· Experimental tools for investigation of oxidation processes (efficiency, by-product formation, reaction kinetics)
· Options for simulating pollutant degradation and disinfection in real water applications
· Insights in reaction kinetics and mechanisms of oxidants used in water treatment
· Influence of water matrix constituents such as organic matter and halides and carbonates
· Integration of oxidation processes in the water treatment chain
· Mechanisms of pollutant degradation and disinfection processes
· Skills to assess the quality of current literature and strategies to evaluate literature as a scientific reviewerFor fostering the learning effect the course is divided in lecture and tutorial
For fostering the learning effect the course is divided in lectures and tutorials
Learning objectives:
The students will learn how to treat individual source waters (e.g., surface water, wastewater or groundwater) on basis of the source water quality (e.g., content of organic matter and halides). Furthermore, experimental setups will be explained to briefly characterise water oxidative processes in bench scale experiments to determine the optimal oxidant dose.
The students will be able to perform all important experiments to investigate oxidation processes in terms of pollutant degradation, disinfection, product formation and energy demand and how to develop strategies for polishing water treatment steps (e.g., strategies for minimizing by-product formation)
The students will learn to assess the quality of research papers and insights on the process of scientific publishing. They will experience the limitations of the peer-review-process.
