Abstract:

In late 2009, WERF embarked on a new study addressing the problem of regrowth, odors, and sudden increase (ROSI) after anaerobic digestion. The research project is evaluating current mesophilic, thermophilic, and advanced anaerobic digestion processes as well as E. coli 1 quantification methods and persistent odors.

The research project is broken into two tracks. The first is focused on filling critical research gaps that will provide fundamental insights for developing monitoring methods and mechanisms for needed solutions. The second phase is focused on developing and implementing solutions in the field where biosolids are land-applied. The research builds on approaches and methods already in use by the project team for related projects and from earlier research.
