Study of waste management treatment facilities using advanced Membrane Bio Reactor (MBR) technology

<p>Sewage treatment plays a crucial role in sustainable urban and industrial development. This study focuses on the generation and treatment of sewage from residential, institutional, commercial, and industrial sources, distinguishing between grey water and black water. While grey water is relatively easier to treat, conventional practices in India merge both streams for processing. This research evaluates the application of advanced Membrane Bio Reactor (MBR) technology in a Sewage Treatment Plant (STP) at an industrial township in Andhra Pradesh, India, to achieve Zero Liquid Discharge (ZLD). The study demonstrates the significant efficiency of MBR technology in removing contaminants, with Biochemical Oxygen Demand (BOD) reduced from 350 mg/L to 20 mg/L, Chemical Oxygen Demand (COD) from 650 mg/L to 50 mg/L, and Total Suspended Solids (TSS) from 150 mg/L to 4 mg/L. Additionally, oil and grease levels decreased from 19 mg/L to 4 mg/L, and total nitrogen dropped from 45 mg/L to 10 mg/L. These results affirm the effectiveness of MBR in producing high-quality treated water suitable for irrigation and toilet flushing. The research involved systematic sampling of influent and effluent wastewater over a set period, employing analytical methods like spectrophotometry and chromatography. Key operational parameters such as flux rate, transmembrane pressure (TMP), sludge retention time (SRT), and hydraulic retention time (HRT) were monitored to optimize efficiency. Comparative analysis with conventional treatment methods highlights MBR’s advantages, including superior pollutant removal, reduced footprint, and lower energy consumption. Real-time sensors and lab-scale MBR setups were used for continuous data collection and statistical analysis, confirming MBR’s effectiveness in sustainable wastewater treatment.</p>
