Abstract |
An optimum system for the lime stabilization of municipal sewage sludge was first developed and then evaluated. The primary objectives of this work were: (1) To determine the degree of stability induced in a sludge by lime addition and (2) to determine the effects of spreading lime-stabilized sludge on agricultural land. Lime doses and contact times required to eleiminate the pathogenic bacteria and odors from a raw sludge were determined by laboratory studies, and the information obtained was translated into design and operational parameters for a pilot scale, continuous flow process. Physical, chemical, and biological characteristics of both the raw and stabilized sludges were measured. Soil and crop studies, both in a greenhouse and on controlled outdoor plots, were performed to determine the effects of spreading lime-stabilized sludge. Effective lime stabilization of sludge was accomplished by elevating the pH to 12.0 with lime addition and maintaining this pH level for at least 30 minutes. |
