Comprehensive Overview of MBR Pool Setup and Membrane Module System   Enhancing Wastewater Treatment Efficiency with MBR Technology As urbanization and population growth continue to increase, the demand for effective and sustainable wastewater treatment solutions becomes more critical. The recent expansion project targeting a treatment capacity of 340 tons/day for domestic wastewater highlights the ultimate advancements in Membrane Bioreactor (MBR) technology. This blog post delves into the specifics of this project, showcasing the critical components and operational strategies of the MBR pool setup. Understanding the MBR Pool Dimensions and Configuration The MBR pool for this project is designed with precise dimensions to ensure optimal performance: - Pool Dimensions: The main pool measures 18.0 x 4.5 x 2.8 meters. It is recommended to segment the pool into an MBR section of 6.0 x 4.5 x 2.8 meters, maintaining a liquid level of 2.5 meters. This segmentation facilitates effective membrane module integration and operational efficiency.  Flat sheet Membrane Modules: The project utilizes PEIER100-200 membrane modules, totaling 5 sets, with each set comprising 200 membranes. The effective surface area per membrane is 1.0 square meter, resulting in a combined membrane area of 1000 square meters. These modules are crucial for filtering and treating the wastewater efficiently.    Membrane Rack Dimensions: The racks are precisely sized at 3370 x 802 x 1880 millimeters to support the membrane modules. Each rack is equipped with a DN40 water output pipe and a DN65 aeration pipe, ensuring optimal flow and aeration. Operational and Maintenance Strategies - Suction Pumps: Two suction pumps are installed, with one operational and one as a backup. The pumps operate in cycles, running for 8 minutes and stopping for 2 minutes. This cyclic operation helps maintain the membrane's efficiency and longevity by reducing fouling and wear. - Air Supply for Membrane Modules: The required air volume is calculated to be 11 cubic meters per minute, ensuring adequate aeration for membrane cleaning and optimal performance. - Installation Precision: Prior to installing the membrane modules, it is crucial to level the pool bottom. The aeration bases must be securely fixed, with a horizontal error margin not exceeding ±2mm. This precision ensures the stability and effectiveness of the membrane system. - Cleaning and Maintenance: The cleaning process for the membrane modules involves a gravity-fed dosing method, with each membrane receiving 4 liters of cleaning solution. If gravity conditions are not feasible, dosing pumps and funnels must be installed to facilitate the cleaning process. The implementation of MBR technology in the 340 tons/day wastewater treatment project demonstrates its potential to revolutionize the industry. By integrating advanced membrane modules, precise installation techniques, and efficient operational strategies, this project sets a benchmark for sustainable and effective wastewater management. As we continue to innovate and refine these technologies, the ultimate goal remains to protect and preserve our precious water resources for future generations.
