“Designing the prototype of sewage treatment plant using Submerged Membrane Bioreactor (SMBR) Technology for Institutional Wastewater”

The present study highlights that the Sequencing Batch Reactor (SBR) is an efficient, flexible, and compact wastewater treatment technology suitable for residential and institutional applications. Based on performance evaluation and analysis, the system demonstrates high removal efficiency of organic pollutants, particularly BOD and TSS (up to 95–98%), ensuring that the treated effluent meets discharge and reuse standards. The working principle of SBR, which integrates equalization, aeration, settling, and decanting within a single reactor, simplifies the treatment process and significantly reduces land requirements. This makes it highly suitable for decentralized wastewater treatment systems, especially in areas where space and infrastructure are limited. This approach aligns with the objectives of your study, where emphasis is placed on compact, efficient, and sustainable STP design for institutional use. Furthermore, the study confirms that biological treatment using microorganisms plays a critical role in pollutant removal. Controlled aeration and cycle operation enhance microbial activity, resulting in effective degradation of organic matter and improved effluent quality. Similar to advanced systems like SMBR discussed in your literature review, SBR also provides high treatment efficiency with relatively lower infrastructure complexity. However, the performance of the SBR system is highly dependent on proper design, automation, and operation. Factors such as cycle timing, aeration control, and sludge management must be carefully maintained to achieve optimal results. Challenges such as power dependency, mechanical reliability, and requirement of skilled operators need to be addressed for long-term sustainability. In addition, the study emphasizes the importance of treated wastewater reuse for non-potable purposes such as gardening, flushing, and landscaping. This contributes to water conservation and sustainable resource management, which is a key objective in modern environmental engineering practices.
