inCTRL had a busy and exciting week at the recent WEFTEC conference in Chicago, IL. Here is a summary of our activities:
Friday, September 25, 2015:

• On the Friday before WEFTEC, we organized an Aeration System Modeling Workshop for 20 experts from utilities, consulting firms, manufacturers and universities. We presented our new comprehensive aeration system model library for SIMBA#. Thank you to all the attendees for their valuable feedback. A special thank you to Black & Veatch for hosting the workshop at their Chicago offices. The aeration library will be part of SIMBA# 2, which will be released soon.


• inCTRL sponsored the popular Jammin’ 4 Water event, an open-mic amateur performance night benefiting water charities.

Saturday, September 26, 2015:

• Leiv gave three presentations in Workshop W05: Using On-Line Analyzers to Meet Stringent Nutrient Requirements: a)Designing Process Control Systems Using Dynamic Models, b) Cost of Ownership – Quality Control and Maintenance Planning for On-line Sensors, c) Innovations in Instrumentation & Control.

• At the Modeling Expert Group of the Americas (MEGA) meeting at 5 PM, Peter Vanrolleghem from the Université Laval passed on chairman duties to inCTRL’s CEO Leiv Rieger. John Copp from Primodal was elected as the incoming vice-chair of MEGA.

• Oliver gave a presentation on the activities of the Biofilm Interest Group (BIG) at the MEGA meeting. Oliver is currently the Vice-Chair of BIG.
Sunday, September 27, 2015:

• On Sunday, Leiv Rieger co-chaired Workshop 21 – Knowledge Development Forum: The Future of Modeling at Water Resource Recovery Facilities with Imre Takács from Dynamita. Oliver Schraa presented on Aeration system modeling and Michael Ogurek from ifak presented the Life Cycle Assessment work we have been collaborating on with ICRA. Lluis Corominas presented results from a research project between ICRA, UC Irvine, and inCTRL on the impact of energy tariff structures on treatment costs.

• Oliver joined the Plant Operations and Maintenance Committee (POMC) meeting.
Monday, September 28, 2015:

• Oliver was the assistant moderator for Session 223, Instrumentation and Control Strategies for BNR Processes on Monday from 3:30 PM to 5:00 PM.
• Leiv presented our new methanol dosage controller for multi-stage WRRFs at 4 pm in Session 223. The presentation focused on methanol-based denitrification process fundamentals and our model-based, self-calibrating control solution.
Tuesday, September 29, 2015:

• The day started with Oliver co-chairing the Biofilm Interest Group’s Annual Meeting at 7:15 AM with Leon Downing from CH2M. A business meeting was followed by presentations from Dr. Robert Nerenberg from the University of Notre Dame and Jeff Peeters from GE Power and Water on membrane-aerated biofilm reactors (MABRs) and a discussion session. The meeting had a record turnout this year thanks to our great speakers!

• Later in the morning, inCTRL’s CTO Oliver Schraa, presented SIMBA#’s new comprehensive dynamic aeration system model in Technical Session 305. SIMBA# can now model blowers, pipes, valves, and diffusers allowing the integration of air supply, distribution, and demand. Engineers can use SIMBA# to holistically analyze aeration systems including oxygen requirements, blower performance, air distribution, valve impacts, and controller design and tuning.

• Over lunch, Leiv attended the meeting of WEF’s Automation and Information Technology Committee (AIT).

• In the afternoon, Leiv Rieger and co-authors received the prestigious WEF Eddy Wastewater Principles/Processes Medal for their paper “Ammonia-Based Feedforward and Feedback Aeration Control in Activated Sludge Processes” from the Water Environment Federation (WEF). The WEF Eddy Wastewater Principles/Processes Medal recognizes research that makes a vital contribution to the existing knowledge of the fundamental principles or process of wastewater treatment.

• In the afternoon, Oliver moderated Technical Session 408, BNR Case Studies from 1:30 PM to 5:00 PM.
Wednesday, September 30, 2015:

• Leiv Rieger moderated Technical Session 523, Model Based Planning and Control Approaches.

• In Session 523, Michael Ogurek from ifak presented the paper we collaborated on with ifak, entitled “A Novel Integrated Approach for Designing, Testing, and Implementing Process Control Solutions”.
As you can see, we were very busy at WEFTEC and have a number of exciting developments related to the modeling, operation and control of wastewater treatment plants (WWTPs). Please contact us if you would like more information or would like to collaborate with us.

Stay tuned as we have more exciting developments on the way!
