Sludge Thickening an overview ScienceDirect Topics

The advantages of sludge thickening in reducing the volume of sludge to be handled are substantial. With reference to Figure 9 3, a sludge with 1% solids thickened to 5% results in an 80% volume reduction (since 5% = 1/20). A concentration of 20% solids, which might be achieved by mechanical dewatering (discussed in the next section), results in a 95% reduction in volume, with resulting
