2022 Pre-Seminar Workshop #3 - Oxygenation and Circulation Techniques to Improve Water Quality in Raw Water, Wastewater, Stormwater, and Managed Lakes & Ponds


0.3 CEUs



This workshop will inform operators, water resource managers, scientists, engineers, and any interested stakeholder in oxygenation and circulation techniques. The workshop will provide a comprehensive review of both theory and practice of oxygenation and circulation techniques. Participants will be provided the tools and training to be able to properly select and design oxygenation and/or circulation system to address a particular water quality issue(s).

Presenter(s): Patrick Goodwin, Good Aquatics and Raymond Menard, Algae Control Canada
