Course Critical Performance and Learning Outcomes

  Critical Performance:
Learning Outcomes:

To achieve the critical performance, students will have demonstrated the ability to:

  1. Identify the principal contaminants of untreated water from various sources, and explain how their removal can provide economic benefits, energy conservation and water conservation in both municipal and industrial settings.
  2. Describe the phenomenon of ionization and explain its significance in water treatment.
  3. Describe the test procedures normally associated with water treatment.
  4. Describe the principal methods used in external water treatment and evaluate them with reference to energy and water conservation.
  5. Describe the principal methods used in internal water treatment and evaluate them with reference to energy and water conservation.
  6. Discuss the use of water treatment in recirculating systems, steam boiler systems, humidification systems, control systems and cogeneration systems, and indicate how such treatment improves energy and water conservation.
  7. Explain how water treatment applies to health and safety, including sewage discharge.
  8. Describe the application of water treatment to potable and domestic water systems and to pool and spa systems for both commercial and residential uses.
