This course will cover drinking water quality and associated public health concerns. Particular emphasis will be placed on the multiple-barrier concept for the inactivation of microorganisms, as well as the preservation of distribution system water quality. A substantial portion of the course will deal with practical design of commonly used treatment processes for the production of potable water.
This course isn't currently offered through IZUNA Part-time Studies. Please check back next term or subscribe to receive email updates.
Upon successful completion, students will be able to:
Appraise the significance of water demand (based on water consumption statistics) and the characterization of water quality in relation to treatment system design.
Assess key bacteriological water quality parameters to ensure the production of potable water according to criteria established under the Guidelines for Canadian Drinking Water Quality and the BC Safe Drinking Water Regulation.
Compare the water treatment philosophies practiced in North America and other parts of the world, including discussion of standards set by the WHO and EEC.
Discuss the significance of source water protection to minimize water quality risks.
Analyze the principles of coagulation/flocculation as they pertain to water treatment plant design.
Analyze the principles of clarification as they pertain to water treatment plant design.
Illustrate the principles of filtration as they pertain to water treatment plant design. Describe conventional, direct, diatomaceous earth, slow sand and membrane processes.
Discuss filter operation, defining the concept of headloss and relationship to backwash requirements and media types.
Apply the principles of water softening to the removal of hardness from scale forming waters, including the calculation of dosage requirements for various water softening scenarios.
Discuss the principles of corrosion control as they pertain to water treatment process design.
Discuss the principles of primary and secondary disinfection as they pertain to water treatment process design. In additional to chlorine based treatment, discuss alternative technologies including ozone and ultraviolet light.
Discuss the formation potential of disinfection by-products and microbial regrowth in distribution systems and their associated exposure risks.
