Wastes from Water Treatment Plants: Literature Review, Results of an Illinois Survey and Effects of Alum Sludge Application to Cropland

摘要

The objectives of the study were to update information on the characteristics and management of wastes from water treatment plants and to assess the benefits and risks of alum sludge application to cropland. The report has three major sections: a literature review; a summary of results of a survey of Illinois water plant wastes; and a discussion of findings from a study of alum sludge for agricultural uses. The literature survey addresses characteristics and management of sludge. The literature review section discusses laws and regulations (PL 92-500, PL 94-580, PL 93-523) regarding waste disposal from water treatment plants.
