Workshop A

Workshop A: Dewatering Optimization Workshop - Practical Ways to Improve Performance
Tuesday, March 31, 2020
8:30 AM – 5:00 PM

The Dewatering Optimization – Practical Ways to Improve Performance workshop will focus on practical solutions to increase dewatering performance including drier cake solids, better solids capture, reduced polymer consumption, and reduced O&M costs for dewatering processes. The information from the workshop will provide municipal attendees the knowledge and resources to better perform their jobs with lower O&M costs, consultants to provide more informative and better dewatering equipment advice and manufacturers to provide better and more optimum machine performance at lower O&M costs.

Workshop B

Workshop B: Seeking the Skinny on Sludge: MOP-8 Stabilization Fundamentals
Tuesday, March 31, 2020
8:30 AM – 5:00 PM

This workshop features authors of the MOP-8 chapter on stabilization and will provide a base of knowledge around fundamentals of stabilization processes (such as design, operation, and construction) so that attendees can incorporate principals learned into their mission in the workplace.

Topics covered in the workshop include:

Comparison of stabilization methods
Process objectives
Process fundamentals such as microbiology
Design fundamentals such as common design parameters and sizing criteria
O&M considerations such as equipment and instrumentation and controls
Construction considerations

Workshop C

Workshop C: Fundamentals of Digestion using Process Simulators
Tuesday, March 31, 2019
8:30 AM – 5:00 PM

As the current utility workforce ages, new training techniques are needed for the next generation of O&M professionals. This workshop will present hands-on operator training incorporating the fundamentals of anaerobic and aerobic digester process operation and troubleshooting augmented with participants using process simulators to demonstrate responses to system loading and operational changes. Each lecture module in the program will be accompanied by participants being led through a series of simulations that will provide examples of system performance including troubleshooting. The simulator platform used does not require any prior experience with modeling software.

Workshop D

Workshop D: Communicating about Emerging Contaminants in Biosolids
Tuesday, March 31, 2020
8:30 AM – 12:00 PM

This workshop will provide the practical tactics needed to engage on the urgent communications needs around emerging contaminants, with a focus on PFAS. Participants will learn about the fundamentals and techniques of public health risk communications and crisis communications, and how to apply them in the water sector. The workshop will provide a window into the responses to recent biosolids concerns around the country, such as in Maine, and share valuable lessons learned. Participants will be presented with a toolkit of resources that can used to conduct communications on biosolids and emerging contaminants, including for the media, digital, advocacy, and public engagement. This workshop will be led by national experts in risk, crisis, and biosolids communications.

Workshop E

Workshop E: Greenhouse Gas Accounting for Wastewater Utilities
Tuesday, March 31, 2020
1:30 PM – 5:00 PM

Participants in the GHG Accounting workshop will learn how to calculate GHG emissions and offsets for water resource recovery facilities (WRRFs), and gain insight into the best ways to optimize their WRRFs to reduce their carbon footprint. The workshop will be split into two main sections: 1) participants will learn about the latest policies and research relevant to GHG accounting, and 2) participants will engage on hands-on GHG accounting exercises.

Tour 1: Ensuring Sustainable and Reliable Solids Management for the Future at MCES
April 2, 2020
1:00 PM – 4:30 PM

MCES’s Metropolitan Wastewater Treatment Plant in Saint Paul is the largest wastewater treatment facility in Minnesota, receiving ~170 mgd (26,800 m3/hr) of influent flow and processing ~240 dtpd (9,070 kg/hr) of biosolids in 2018. The plant has been incinerating wastewater solids for 80 years and has one of the most advanced and highest-performing air pollution control systems in the country. Now, MCES is planning for the future, with plans to spend $180 million to add a fourth incinerator and renew its existing solids treatment facilities to ensure operational reliability and continued minimal impact on the surrounding community and the environment. The presentation and tour will discuss our customized project communications tools (https://metrocouncil.org/metrosolids) and will highlight MCES’ objectives including: Maintaining Exceptional Air Quality, Recovering Energy, Ensuring Cost Effectiveness, Keeping Greenhouse Gas Emissions Low, and Ensuring Overall Low Impact.
