Nutrient Removal Course

The Colorado Water Quality Control Commission adopted new nutrient criteria in Regulation 31 and Regulation 85 in 2012.  The nutrient criteria have operational and capital expenditure implications for all wastewater treatment plants in Colorado.  This course will walk attendees through the new regulatory requirements and basic and advanced themes in nitrogen and phosphorus removal.  The course is focused on operational considerations and troubleshooting.

No classes scheduled for 2017.
