About

The course deals with the fundamentals and critical analysis of chemical processes one encounters in the field of Environmental Engineering. The course deals with:

Application of equilibrium equations and material balance equations to calculate conditions in environmental systems at equilibrium using the concept of components.

Use of chemical equilibrium programs such as VMINTEQ to calculate conditions in environmental systems at equilibrium

Application of kinetic equations, stoichiometric relationships and material balances to calculate conditions in environmental systems in which reactions occur that are not at equilibrium.

Application of fundamental aspects of thermodynamics to describe equilibrium conditions in environmental systems.

Defining equilibrium and kinetic limitations as relating to environmental systems and the relative importance of each for chemical processes in environmental systems.

Knowledge of important terminology for chemical processes occurring in environmental systems

Intended audience: Environmental engineering professionals and students pursuing a degree with emphasis in Environmental engineering

Prerequisites: Entry level chemistry course
