Effluent and Waste Treatment

Recommended Prerequisites

Background on General Chemistry.    

Teaching Methods

 Theoretical (by using multimedia projector) and theoretical-practical training to discuss case-studies.   

Learning Outcomes

Students must recognize environmental issues related with solid, liquid and gaseous wastes; it is expected that after this unit students have the ability to propose appropriate processes of waste treatments.

They should be able to recognize and apply basic concepts and principles in Environmental Chemistry; to apply the acquired knowledge in accordance with a professional approach; to have the ability to solve problems within the field of Environmental Chemistry; to have the ability to characterize an effluent, to determine its source and propose appropriate treatment techniques; to make decisions based on scientific grounds; to be capable to communicate and to pass information by using a clear speech and appropriate wording; to have acquired skills that allow to present a communication, and to argue as well, for an expert audience ; to acquire skills to enable self-learning throughout life.
