ABSTRACT:The rapid increase in wastewater generation due to urbanization and institutional activities has created a significant demand for efficient, compact, and sustainable treatment technologies. This study focuses on the design and performance evaluation of a Sewage Treatment Plant (STP) using Submerged Membrane Bioreactor (SMBR) technology for institutional wastewater. The SMBR system integrates biological treatment with membrane filtration, enabling effective removal of organic pollutants, suspended solids, and microorganisms, and producing high-quality effluent suitable for reuse.The research includes estimation of wastewater generation based on population data, laboratory analysis of influent characteristics, and detailed design of treatment units such as collection tank, aeration tank, and membrane bioreactor. Performance evaluation is carried out based on parameters like Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS).The results indicate that SMBR technology achieves more than 90% removal efficiency of organic pollutants and produces clear, reusable water, making it highly suitable for decentralized wastewater treatment systems in institutions. Its compact design, operational reliability, and ability to meet environmental standards make SMBR a sustainable alternative to conventional sewage treatment methods.
