Density of sludge
WebJul 1, 1991 · The density of activated sludge solids at a given treatment plant over a period of time was relatively constant. However, at different treatment plants densities ranged from a low of 1.02 to a high of 1.06 g/ml, indicating that plant operations may influence solids density. Using the measured density of secondary solids, variation in … WebNovel alum sludge-based floating treatment wetland (FTW) was developed to enhance the purification performances of natural water bodies, i.e., rivers, lakes, and ponds.
