Lime Stabilization of Sewage Sludges, is recognized that chemical stabilization with lime does not reduce the organic material in the sludge or result in its permanent stabilization. Only a prolongation of the time required before microbial break-down takes place can be expected. However, in many cases temporary stabilization is suffic

Research, Development and Demonstration in Municipal Wastewater Sludge Treatment, Use and Disposal:A to prepare research programs for sludge treatment, use and disposal and then designate high priority projects, there is not much likelihood that the programs would look the same. We have a common appreciation of the incomplete and needed work in this research area, but our different points of view

Sludge Age and Stability,ludge age and its effects on biological treatment processes; and storage time as it affects the properties of organic sludges. In both of these areas the time element has significant effects on process performance and product characteristics but in rather different ways.

Chemical Properties,acterized with respect to reuse as a fertilizer but ill-defined with respect to characterization for possible impact as a hazards waste. This situation exists because of the multitude of sludge types and the many analytical techniques which have been employed on these sludges.

Lime Stabilization of Sewage Sludges, a prolongation of the time required before microbial break-down takes place can be expected. However, in many cases temporary stabilization is sufficient and lime stabilization is therefore used at several treatment plants.
