WebbActivated 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. Webb1 maj 2024 · Waste activated sludge (WAS) is a by-product of wastewater treatment plants (WWTPs) and its efficient dewatering is a worldwide problem (Wei et al., 2024). A lower water content of dewatered sludge could reduce its volume, and further make sludge easier to be transported and disposed of (Zhen et al., 2024 ). fit foods locationsWebbVibrair oxygen transfer efficiency is 2 to 3.6%%.m -1 for an SAE of 1.6 to 2.1 kgO 2 · kWh –1 and an AAE of 1.4 to 1.7 kgO 2 · kWh –1 in sludge.
