  • 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 savings

  • Sludge Thickening an overview ScienceDirect Topics

    The main targets of sludge treatment are volume reduction and substance degradation. 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

  • Sinter plant Wikipedia

    Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical

    2L of digested sludge was withdrawn from the digester. Part of the withdrawn sludge volume was then thickened. Thickening polymer (Zetag 8169, BASF) was added to the digested sludge to obtain 4g/Kg dry sludge. The sludge was stirred at 400 rpm for 2 min and thickened by gravity to about 5% dry solids content. A pre-determined volume of the
