The present study examines the evaluation of Sewage Treatment Plants (STPs), specifically emphasizing their effectiveness in the treatment of industrial wastewater. This study investigates a range of biological processes, encompassing aerobic, anoxic, and anaerobic treatments, with the aim of assessing their efficacy in the treatment of both inorganic and organic industrial wastewater. Furthermore, the research examines the application of several treatment methods, including the Activated Sludge Process (ASP), Extended Aeration (EA), Moving Bed Biofilm Reactor (MBBR), and Sequential Batch Reactor (SBR), within Sewage Treatment Plants (STPs). This study seeks to offer significant insights into the optimization of sewage treatment plants (STPs) to enhance the efficiency of industrial waste management. This will be achieved through a thorough investigation and comparison of relevant data and information.
