INSTRUCTOR:
Lee H. Odell, P.E., M.ASCE
Purpose and Background
Drinking water technologies are rapidly changing to meet a variety of regulatory requirements, emerging contaminants, and customer demands. This course will focus on understanding how these technologies work and when to apply them. Knowing the breadth and depth of drinking water technologies is important for anyone involved in drinking water.
Benefits and Learning Outcomes
Upon completion of this course, you will be able to:
- Identify appropriate residual handling requirements, disposal technologies, and understand the challenges in residual disposal.
- Describe how monitoring technologies and regulations are used to ensure water quality in the distribution system.
- Distinguish modern surface water treatment methods from past methods, and describe this evolution.
- Learn why chemical mixing, charge neutralization, and floc formation are critical components of all surface water treatment processes.
- Describe the different types of clarification systems used in earlier plants and the advantages/disadvantages of each method.
- Identify what new technologies can be applied to disinfect water to the same degree as we can detect contaminants.
- Explain chemical feed system design and design considerations.
- Explain the evolution of different groundwater treatment systems and the drivers that led to this evolution.
- Describe the application and uses of less commonly deployed technologies used for the removal of contaminants found in groundwater.
- Describe the various sources of marginal water and the technologies used for treating the water.
Assessment of Learning Outcomes
Achievement of the learning outcomes by attendees will be assessed through (3) exams.
Who Should Attend?
- State drinking water regulators
- Civil and environmental engineers
- Public agency engineers
- Hydrogeologists
- Water resource engineers
How to Earn your CEUs/PDHs
This course is worth 2.4 CEUs/24 PDHs. To receive your certificate of completion, you will need to complete (3) exams and receive a passing score of 70% or higher.
How do I convert CEUs to PDHs?
1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
