WTTP 2061
Inorganic Species in Water

1.0 Credit


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.

Delivery Method



Industry experience or completion of level two portion of the Water Treatment Technology. WTTP 2051 recommended.


  • 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 Outline

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

Maximum Completion

30 weeks.
