Precon Workshop 1: The Activated Sludge Process and How to Use Lab Data to Monitor & Troubleshoot Your Treatment Process
8:00am - 4:30pm
Session Chair: Erika Schwender, Professional Training Association;
During this workshop we will explore how the activated sludge process is applied in the various treatment processes such as conventional activated sludge treatment plants, oxidation ditches, and sequencing batch reactors. We will discuss different treatment strategies that can be utilized to achieve specific outcomes and which parameters to monitor to optimize your treatment process.
The Activated Sludge Process & using Lab Data for Process Control
Erika Schwender, James Lee
Professional Training Association, United States of America;
“Process Control” is a big topic and successful process control requires in depth knowledge of many different areas of wastewater collection and treatment. During this workshop we will explore how the activated sludge process is applied in the various treatment processes such as conventional activated sludge treatment plants, oxidation ditches, and sequencing batch reactors. We will discuss different treatment strategies that can be utilized to achieve specific outcomes and which parameters to monitor to optimize your treatment process. In addition, we will explain how to:
interpret lab results for tests like TSS, VSS, BOD, alkalinity, microscopy, nutrients, etc. and what they mean for your treatment process
use lab data to monitor the performance of your treatment process
decide which test to request to get the answers you need to fine tune or troubleshoot your operation
identify the best location and time to collect a sample for the purpose you have in mind
We will focus on everyday operations activities and how you can make changes to improve operational efficiency and effluent quality. This workshop is designed to be an interactive class so please bring questions, problems, and scenarios you encountered at your facility to discuss throughout the day.
8:00 Welcome & Intro to Workshop
8:15 - 10:00 Principle operations of an AS system: How we apply AS treatment in other treatment designs than conventional AS systems, e.g. oxidation ditch, SBR, package plants, etc.
10:00 – 10:15 Break
10:15 - 12:00 Treatment Strategies
12:00 – 1:00 Lunch
1:00 - 2:15 Lab data – what tests do we generally perform in WW treatment (DO, pH, TSS, VSS, BOD, CBOD, TS, VS, Alkalinity, VA, Nitrate, Ammonia, TKN, Total & Ortho Phosphate, etc.); What do these numbers mean? Where's the best location to test for them?
2:15 – 2:30 Break
2:30 - 4:30 How can we use this information to optimize or troubleshoot our treatment process?
