How Low Can You Go? Is Retention Under 10 Days Possible with Thermal Hydrolysis?
Traditionally municipal anaerobic digestion systems have been designed to provide sufficient retention time to make stable biosolids for a variety of outlets. However, retention times have been long to accommodate the difficulty to degrade sludge. Currently, most digestion plants are designed with approximately 20 days of retention.
Thermal hydrolysis increases the biodegradability of sludge such that long retention times are no longer required. This saves money on new facilities, or increases capacity on existing works. In addition, work has shown that anaerobic digestion deteriorates the dewatering benefits of thermal hydrolysis.
This presentation highlights work looking at the influence of retention time on a variety of parameters related to sludge digestion and dewatering, and then look at how these results can influence the design of anaerobic digestion moving forward.

Dr. Matthew Higgins
Dr. Higgins is an international expert in Biosolids and Sludge Treatment. He is a full-time professor at Bucknell University since 1995 and for the last 20 years he has focused much of his research on biosolids issues such as digestion, advanced digestion, conditioning and dewatering, mechanisms for production and control of odors, and the sudden increases and regrow.
Dr. Bill Barber
Technical Director
Dr. Bill Barber is the Technical Director for Cambi Inc. in North America. In this role he develops biosolids projects and assists with research. Prior to this, Bill worked for AECOM in North America and Australia providing consulting services for biosolids projects.
Previously, Bill worked for the UK’s largest Water Utility – United Utilities, in a variety of strategic, technical, financial and research roles related to biosolids and was instrumental in the development of Europe’s largest thermal hydrolysis project. He has also developed a carbon model for United Utilities and his work is well published in WEF technical bulletin.
Bill is a reviewer for several peer review journals and recently an author of IWA’s book on Sludge Thermal Hydrolysis - Application & Potential. Bill has a PhD and degree in Biochemical Engineering from Imperial College, London and is a Chartered Engineer.
