This report developed standard, detailed protocols for conducting tests to assess stability in biosolids products. The testing methods evaluated in the study include specific oxygen uptake rate, volatile solids reduction (VSR) and additional volatile solids reduction (AVSR), pH and changes in pH, and carbon dioxide evolution. The report presents the stability testing protocols in a more usable format than is currently available. Published by WERF. 215 pages. Soft cover.
