Abstract: The workshop on “Pre-treatment strategies for high-rate methane and hydrogen recovery” will provide the insights of the pre-treatment technologies and its potential benefits in anaerobic digestion processes. Specifically, the effectiveness of pre-treatment process in regulating the microbial community shifts, metabolic pathways, and methane, hydrogen (and nutrient) recovery from anaerobic digesters. It also covers the additional topics including, but not limited to, fate of persistent organics, change in pathogen loads and antibiotic resistance gene distribution and energy mass balance of integrating the process and pre-treatment technologies with anaerobic digestion.

Major Themes:

1.Understand the pre-treatment requirements and optimize AD technology 

2.Mass and energy balance for different pre-treatment integration with AD

3.Fate of recalcitrant and emerging contaminants during pre-treatments

4.Microbial community distributions in AD and environmental benefits

Can we use dynamic membrane bioreactors (DMBRs) to intensify and expand AD applications?

Friday, June 17th, 1:30pm - 5:00pm

Rackham Graduate School

Organizers: Tim Fairley-Wax, University of Michigan

Lutgarde Raskin, University of Michigan

Steven Skerlos, University of Michigan

Abstract: Anaerobic dynamic membrane bioreactor (AnDMBR) technology is an emerging approach for low-pressure filtration for waste/wastewater treatment. The technology utilizes a biofilm developed on a mesh support to achieve liquid/solids separation, which also contributes to biological treatment. Due to AnDMBR’s relatively lower fouling propensity than conventional AnMBRs, AnDMBRs have been proposed as a low-cost alternative. Some studies have shown that AnDMBRs may be particularly well-suited to handle higher solids waste streams, such as wastewater sludge or food waste. Other studies have investigated using AnDMBRs for non-biogas AD applications, such as for the production of specific acids. In this workshop, participants will learn about i) the development of AnDMBR technology, ii) approaches to characterize the biofilm layer and evaluate filtration resistance, iii) design considerations and lessons learned to date about operation, and iv) application scenarios for AnDMBRs that conventional AnMBRs cannot serve well.

Better BMP: How to accurately measure biochemical methane potential

Saturday, June 18th, 8:30am - 12:00pm

Rackham Graduate School

Organizers: Sasha D. Hafner, Consulting LLC, USA

Konrad Koch, Technical University of Munich, Germany

Abstract: Measurement of biochemical methane potential (BMP) is essential for anaerobic digestion (AD) research and practice. But the quality of measurements given in peer-reviewed papers and reports vary widely, contributing to low reproducibility in BMP. The purpose of the workshop is to teach participants how to accurately measure BMP and to critically evaluate results. The workshop will cover BMP theory, measurement principles, methods, test design, data collection, data processing, and BMP test validation. A combination of teaching methods will be used in order to encourage participant engagement and knowledge retention. Participants should bring a computer in order to explore the Standard BMP Methods website (https://www.dbfz.de/en/BMP) and use the Online Biogas App OBA (https://biotransformers.shinyapps.io/oba1/).

Mainstream municipal anaerobic treatment – Principles to practice

Saturday, June 18th, 8:30am - 5:00pm

Rackham Graduate School

Organizers: Glenn Daigger, University of Michigan

B. Conall Holohan, NVP Energy & National University of Ireland, Galway

Frank Rogalla, Aqualia

Chungheon Shin, Stanford University

Aleksandra Szcuka, University of Michigan

Abstract: Principles, advances and perspectives of the next generation of municipal wastewater treatment – mainstream anaerobic sewage treatment. Learn the microbiological, engineering and real world process implementation principles from the experts in the field. Using case studies of lab-trials through to full-scale WWTPs presented the fundamentals of the process, the challenges has and is encountering will be presented. Moreover, the currently knowledge gaps limiting the process from becoming ‘business as usual’ will be discussed in roundtable format  get the knowledge to join the field. Through cross-sectorial experts and attendee at this workshop we hope to share the core knowledge to allow experts and young water professionals to join this field and together develop a community of practice and network that will drive mainstream anaerobic treatment forward to assist sewage treatment global in a time of climate emergency when it is most needed. The workshop outcome will be a network of expertise across sectors in the field – developing into a community of practice with a critical review technical document (potentially publishable) to guide principles, advances and future perspectives/knowledge gaps.

Presenters: Information on speakers will be provided soon.

Anaerobic digestion, a technology to help solve Water, Sanitation, and Hygiene (WASH) concerns in resource constrained communities

Abstract: Conventional kinetic and stoichiometric models predict the performance of anaerobic digestion (AD) systems and have helped facilitate the development, optimization, and deployment of AD systems for valorizing waste. In turn, more in depth understanding of the microbiomes and biochemical reactions involved in AD processes, innovations in AD operating strategies, and developments of novel high-efficiency AD systems have led to expansions of these models. Such expansions include the refinements and extensions of existing biochemical model frameworks, such as Anaerobic Digestion Model 1 (ADM1), the utilization of data-driven methods for system performance prediction, and the establishment of metabolic model frameworks based on high-quality genomes from mixed anaerobic microbiomes. In this workshop, presenters will share innovations and visions for AD modeling and explore emerging modeling practices for anaerobic bioprocesses. Workshop participants are invited to identify knowledge gaps in current model practices, share their thoughts on the needs in research and practice, gain hands-on experience in using the novel modeling frameworks.
