Abstract
Alkaline or lime stabilization is a very simple process. Its principal advantages over other stabilization processes include low cost and simplicity of operation. However, lime stabilization accomplished at a pH of 10.0–11.0, may allow odors to return during storage owing to pH decay. To eliminate this problem and reduce pathogen levels, addition of sufficient quantities of lime to raise and maintain the biosolids pH to 12.0 for 2 h is required. The lime-stabilized biosolids readily dewaters with mechanical equipment and is generally suitable for application on an agricultural land or disposal in a sanitary landfill.
