Principles of Wastewater Treatment

IWES, University of Queensland, WaterAid Wastewater treatment

Target Audience

Engineers, scientists and managers who require an excellent introduction to the principles of wastewater treatment.

Description

The aim of this course is to teach the key enabling scientific and process engineering fundamentals which underpin wastewater treatment processes. These are taught via real wastewater treatment problems and case studies.

This is the most popular wastewater fundamentals course offered in Australia. Now featuring site visits, real case study data and exercises, and state-of-the-art multi-media teaching resources.
