residuals
The solids generated or retained during the treatment of wastewater. They include trash, rags, grit, sediment, sludge, biosolids, septage, scum, and grease, as well as those portions of treatment systems that have served their useful life and require disposal, such as the sand or peat from a filter. Because of the different characteristics of residuals, management requirements can differ as stipulated by the appropriate federal regulations.
