Wastewater Chemistry

Issues adressed:

This 12hr course 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.

Issues addressed

DAY 1 Chemistry Basics

  • Water and wastewater chemical reaction types, equilibrium and kinetics
  • Introduction to chemical calculation tools – Calculating in Excel and using PhreeqC
  • Gas exchange – solubility, mass transfer, design and operation
  • Minerals precipitation – solubility, rates

DAY 2 Operation and Analysis

  • pH control in wastewater and water processes
  • Estimating and controlling inorganic scale formation
  • Nutrient recovery using physico-chemical processes
  • Sewer sulfide control with chemicals
  • Disinfection in water treatment, dosing and chemicals

What do you get?

• 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.

Who should attend?

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.
