This series of webinars and workshops is targeted for water resource recovery facilities (WRRF) staff and will cover the fundamental concepts of operating biological and chemical water resource recovery systems to achieve various treatment objectives. Two primary focus areas for the training are nutrient removal and sludge digestion processes.

The webinar training session format will have a typical duration of 90 minutes and will include a presentation of fundamental concepts related to that topic. Each main topic covered will be supported by real-world examples and/or computer simulations performed by the instructors to illustrate the relationships between key process parameters and plant performance.

The workshop training format will typically have a longer duration of 3-4 hours and will provide a greater depth of subject matter. In addition, the workshop format will include a hands-on component by providing participants with access to process simulator software. The workshop format includes a series of modules with each covering a fundamental treatment concept, that will then be followed up with attendees being led through a series of simulations to demonstrate how the concept is applied to a plant layout. Following completion of the modules and example simulations, participants will be given problems to solve on their own, with solutions provided at the end of the problem-solving period.

The simulator software will be provided in advance of the workshop to allow participants to become familiar with the state-of-the-art SimuWorksTM software developed by Hydromantis. This program is commonly used for treatment process evaluation and design, but has been enhanced to serve as a platform for plant O&M manuals and operator training. This software is the basis for the simulator event included in WEFTEC Operations Challenge.

Presenter Information

Paul Dombrowski has more than 30 years of professional experience and is currently the Chief Technologist with Woodard & Curran. He has led the evaluation and design of numerous plant upgrades many that that focus on nutrient removal. Paul has contributed to numerous journal articles and textbooks including many recent WEF Manuals of Practice. In recognition to his contributions to wastewater design and operations, Paul has received the NEWEA Peloquin Award, the EPA Region 1 Trainer Award, the WEF Morgan Operational Solutions Medal, the WEF Furhman Medal and has been recognized as a WEF Fellow. He is a professional engineer, a board certified environmental engineer and certified wastewater operator.

Spencer Snowling has enjoyed working on many interesting and challenging simulation projects during his 20 years as part of the product development team at Hydromantis Environmental Software Solutions. He’s had the opportunity to apply advanced simulation technologies to process troubleshooting and optimization projects at municipal and industrial wastewater treatment systems around the world. He also enjoys a keen interest in the development of simulation-based teaching tools, and led the development of the simulator used in the annual WEF Operations Challenge competition. Spencer is also an adjunct professor at McMaster University in the Dept of Civil Engineering.
