Subject Title
Water Treatment

Subject Description
This subject covers the key concepts in the field of water treatment as applied to the protection and operation of building mechanical systems.

Credit Status
One credit toward the Building Environmental Systems (BES) Operator Class II Certificate

Learning Outcomes
Upon successful completion of this subject the student will be able to:

- 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.

- Describe the phenomenon of ionization and explain its significance in water treatment.

- Describe the test procedures normally associated with water treatment.

- Describe the principal methods used in external water treatment and evaluate them with reference to energy and water conservation.

- Describe the principal methods used in internal water treatment and evaluate them with reference to energy and water conservation.

- 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.

- Explain how water treatment applies to health and safety, including sewage discharge.

- Describe the application of water treatment to potable and domestic water systems and to pool and spa systems for both commercial and residential uses.

- Provide guidance in the implementation of a water efficiency program in the buildings sector.
