Took a rather dry subject and explained in an easy to follow, accessible manner. Had great knowledge of the subject matter. I liked the combination of theory of guidelines combined with active examples from SEQ water. - Sydney 2016 View all testimonials

Wastewater Chemistry

This course is not currently scheduled for a future event

This course addresses the essentials of wastewater chemistry, including:

  • The forgotten basics, such as the periodic table of elements, molecules and ions;
  • The importance of chemical conditions such as pH, alkalinity, saturation extents and redox; and
  • Chemical reagents, how they work.
The course content (day 1) is reinforced by a series of application area workshops (day 2) including control of turbidity, sewer corrosion, odour control, inorganic scale prevention, nutrient recovery and biofouling. The course also discusses operational set-points for chemical dosing. The course does NOT deal with biochemistry.

This highly interactive course uses a series of workshop based exercises to introduce basic chemistry concepts.  The course will use spread-sheeting extensively, and participants should bring a laptop computer (with Microsoft Excel installed).  Macros should be enabled.


Day 1: Chemistry Basics

  • The periodic table of elements, molecules and ions
  • Writing and understanding chemical reactions
  • Concentration, moles
  • Equilibrium, pH, acids and bases, alkalinity
  • Minerals precipitation, gas exchange and saturation extents
  • Redox

Day 2: Operation and Analysis

  • Application workshop - odour control
  • Application workshop - turbidity, including Jar testing
  • Application workshop - inorganic scale prevention
  • Application workshop - nutrient recovery
  • Application workshop - sewer corrosion
  • Application workshop - biofouling


  • Access to world class wastewater chemist
  • Workshops on real applications with wastewater
  • Core skills and tools to take back to your workplace, which will enable you to analyse and trouble-shoot your wastewater problems
  • A USB containing all electronic materials used in the course including basic Microsoft Excel spreadsheet calculation tools.


This course is of particular relevance to practitioners in the wastewater sector, or for people in process operations roles where chemicals are dosed for wastewater treatment.
