Description:
Treatment of municipal sludges to produce biosolids which meet federal and/or state requirements for land application requires process monitoring. The goal of process monitoring is to produce biosolids of consistent and reliable quality. In its simplest form, for Class B treatments, this may be monitoring the pH of an alkaline treatment or determining flow rates, temperatures and volatile solids reduction of mesophilic anaerobic or aerobic digesters. However, to achieve Class A, process monitoring includes observation and recording process conditions as well as monitoring indicator microorganisms or specific pathogens (U.S. EPA, 2003).
