WTTP 2061: Inorganic Species in Water

The focus of this course is on the study of inorganic species (metals and non-metals) that are found in water and wastewater. Topics include identification and removal techniques of inorganic species in treatment systems. Basic terminology, reactions and equation analysis are also covered.

Learning outcomes

  • Identify common metals and non-metals that are important for water treatment
  • Identify redox reactions and explain what is meant by the terms oxidations and reduction
  • Explain the process of complexation
  • Explain the concept of conductivity
  • Understand a simple electrochemical cell
  • Describe the acceptable levels of metals and non-metals in drinking water
  • Describe the possible environmental sources, both natural and non-natural, of metals and non-metals
  • Identify important anions and cations in water
  • Explain how conductivity is measured
  • Explain the removal process, such as aeration, sedimentation, filtration and ion exchange for inorganic species in water
  • Outline some analytical processes for determining inorganic content in water

Course topics

The course is divided into three major sections:

  • Section 1: Introduction/Review
  • Section 2: Electrochemistry and Conductivity
  • Section 3: Metals and Nonmetals: Issues, Treatment, and Analysis
