An activated sludge treatment system is a living ecosystem and requires special care to ensure that the organisms are healthy and provided with the proper environment for them to flourish. There are many factors that can have an effect on the efficiency and overall operations of an activated sludge treatment plant and there are many operational adjustments that need to be made on a daily basis to keep the system running at its best. Two calculations that are often used to determine those adjustments are food/microorganism (F/M) ratio and mean cell residence time (MCRT).

Electronic materials are included with registration.

Zoom information and student guide are included in your order confirmation.

Each operator must be able to log into Zoom individually with a single device for Contact Hours**.

Prior to class, attendees will need their own zoom account which includes their name, phone number and possibly email address. 

Attendees can use a computer, phone, or tablet to attend program, however, for the best experience, a device with a web cam and speaker is best.

**Attendees can share a computer for viewing. But, each attendee must also log into a device individually (e.g. View on computer at the plant as a group, but also log into Zoom individually with your phone). Attendees must individually answer periodic poll questions and take quizzes during program. This is necessary to verify attendance and participation. This will involve typing into a device.
