Biosolids Technology Fact Sheet Gravity Thickening

Specific Design Criteria Nearly static conditions are required in gravity thickening tanks in order to induce settlement. Therefore, the tank design must ensure a smooth, continuous flow of liquid at the center well, the xinhais, and the solids removal point.

Process Design Manual Sludge Treatment And Disposal

Figure 410 presents data collected for several activated sludges resulting from the treatment of various type wastes. The airtosolids ratio needed for a particular application is a function primarily of the sludge's characteristics such as SVI. The most common ratio used for design of an excess activated sludge thickener is 0.02.
