Water Pollution and Wastewater Treatment

It is recommended the knowledge acquired in previous units of the degree, namely in Chemistry, Fluid Mechanics, Microbiology and Separation Processes.

Theoretical classes lecturing the contents of the curricular unit using, whenever possible, the presentation of practical examples. In theoreticalpractical classes, after a general discussion about the problems, students are encouraged to continue with its resolution and at the end a discussion of the results is made. The evaluation is done by a final exam and consists of a written exam

This course provides students with knowledge of the main problems associated with water pollution and the most common methods of treating wastewater. After an introduction to the theme of water pollution, the main pollutants are identified and the most important wastewater treatment systems are described. It is intended that at the end of the frequency of this course students should: i) understand the functioning of the main wastewater treatment technologies; ii) dimension some of the described wastewater treatment processes; iii) know the main legal requirements about water; iv) understand the operation of a wastewater treatment plant and v) identify and understand the importance of the biotic component of such systems
