Course description and aims
This lecture provides the knowledge and tools necessary to understand a range of environmental aqueous processes in natural waters (river, lake, ocean and so forth) and engineered waters (water and wastewater treatment systems). In the first 5 classes, students learn fundamentals in chemical reaction including thermodynamics and kinetics. The next 5 classes introduce specific reactions that occur in natural and engineered waters including acid-base, complexation and redox reactions. The last 5 classes provide some examples (e.g., nutrient cycles in watershed, disinfection in drinking water treatment, fate and behavior of organic contaminants, etc.) to which the aforementioned chemical theory can be applied in natural and engineered systems.
All over the world, the aquatic environment is expected to be the place which serve a good quality of water resource to human society and accommodate fruitful ecosystem and this can be achieved by properly managing and preserving water quality. This lecture aims to cultivate the ability of students, by using chemical reaction theory, to quantitatively assess the influence of human activities to the water quality and ecosystems including impact of wastewater discharge and climate changes to the water quality formation in watershed and transformation of water quality in treatment processes.
Student learning outcomes
By the end of this course, students will be able to:
• Understand fundamental concept and theory that govern aqueous environmental processes including thermodynamics, kinetics and non-ideal system modeling.
• Understand a range of aqueous processes including acid-base equilibrium, oxidation-reduction reactions, elementary and complex reactions, mass balance and transport, multiphase reaction modelling (solid/water/air interface processes).
• Apply problem-solving algebraical, geometric and computational tools for the quantitative characterization and prediction of water quality composition in the engineered water and also natural waters.
• Understand the impact of human activities (e.g., wastewater discharge and climate change) to the water quality in river, lake, coastal and oceanic waters
