The most common conventional processes include sludge thickening, dewatering, and drying. Figure 9.1 presents the sludge solid content (% of dry mass) during the sludge dewatering processes. After thickening, the sludge mass is usually reduced up to 70% of the initial value, due to water loss, and the solid content reaches 2-3%.

Introduction to sludge dewatering. Dewatering processes provide a concentrated, consolidated product − retaining most of the solids from the original sludge along with a diluted stream which is predominantly water. Dewatering processes apply a significant mechanical force to achieve increased water removal over that possible from thickening.
