WebActivated sludge treatment process (ASTP) is the most common classification of biological treatment process used in the IW treatment. Basically, industrial effluent contains suspended impurities that are reduced using ASTP (aeration tank) with the help of oxygen sources present and microorganism. A schematic of ASTP is shown in Fig. 9.4. http://www.soe.uoguelph.ca/webfiles/rzytner/WQ/sludge_volume.pdf

WebIn the activated sludge treatment process, the removal of suspended solids from wastewater is usually through gravity separation in a clarifier. The activated sludge (excess biomass or cell mass) removed from the secondary treatment process. For most treatment plants, this will be a portion of the Return Activated Sludge (RAS) flow stream. WebIn a typical case, the process begins with a sludge that has been dewatered to a DS content of some 15 percent. The sludge is mixed with steam in a pulper, and this hot homogenized mixture is fed to a reactor, where it is held under pressure at approximately 165 °C (about 330 °F) for about 30 minutes. common items speech therapy
