IChemE Approved Online CPD Course

Biological Wastewater Treatment and Anaerobic Digestion: Theory, Design and Practice

Course lecturer: Dr Davide Dionisi
School of Engineering
University of Aberdeen

The University of Aberdeen is delighted to offer this IChemE Approved online CPD Course which is aimed at professionals and PhD students working in the areas of biological wastewater treatment and anaerobic digestion.

This advanced course describes how to optimise and design biological wastewater treatment and anaerobic digestion processes in order to maximise treatment efficiency while minimising the capital and operating costs.


The course starts from the fundamentals of the biological processes relevant for wastewater treatment (e.g. kinetics and stoichiometry, COD balance, aeration and settling) and moves to their application to the design and optimisation of the following processes: activated sludge (carbon and carbon and nitrogen removal), anaerobic digestion, sequencing batch reactors, attached growth processes.

What is covered:

  • Fundamentals of biological wastewater treatment
  • Kinetics and stoichiometry of biological reactions
  • Step-by-step process of how to develop and solve the mass balances and design equations
  • The main processes used in the industry are described and the corresponding design equations are developed
  • The course includes numerical examples and design problems, solved by the course lecturer using Microsoft Excel.
