You know what a wastewater clarifier does in a general sense---solids go in the bottom, cleaner water comes out the top---but how do you handle the nitty gritty of day-to-day clarifier operation? How do you understand what's happening? How do you troubleshoot?

This week's video offers some answers. It begins with a very brief refresher on the basics and then goes on to dive in to state point analysis and troubleshooting scenarios. It's just under 15 minutes and includes clear diagrams and visuals to help guide you through the concepts.  And if you click through to YouTube, there's a link to the spreadsheet used in the second half.
