At DEW, we are committed to pioneering sustainable wastewater treatment solutions that meet the evolving needs of communities and industries. One of the most advanced systems we offer is our sewage treatment plant with Membrane Bioreactor (MBR) technology. This cutting-edge approach combines conventional activated sludge processes with sophisticated membrane filtration to deliver superior effluent quality and efficient solid-liquid separation. Here’s an in-depth look at how our MBR technology works and the benefits it brings.

How Our MBR Sewage Treatment Plant Works

  1. Collection and Preliminary Treatment : The process begins with the collection of raw sewage and wastewater from diverse sources, including households, industries, and commercial establishments. The wastewater first undergoes preliminary treatment, which includes:
    • Screening: Removing large objects such as plastics, rags, and other debris.
    • Grit Chambers: Eliminating heavy solids like sand and gravel.
  2. Biological Treatment: The wastewater then enters the bioreactor, a critical component where biological treatment occurs. Inside the bioreactor:
    • A mix of microorganisms (biomass) breaks down organic matter and pollutants.
    • The activated sludge process is employed, with air or oxygen supplied continuously to promote the growth of microorganisms that consume organic contaminants.
  3. Membrane Filtration: Incorporated into the bioreactor is the MBR system, which features advanced membrane filtration technology:
    • Membrane Filtration Unit:** Acts as a physical barrier, selectively allowing treated water to pass through while retaining suspended solids, bacteria, and other contaminants.
    • Types of Membranes: We use either submerged membranes within the bioreactor (submerged MBR) or membranes placed externally (sidestream MBR).
  4. Solid-Liquid Separation: The membrane filtration unit facilitates effective solid-liquid separation:
    • Permeate Collection: The treated water (permeate) passes through the membrane and is collected for further treatment or discharge.
    • Sludge Concentration: Retained solids, including microorganisms, are concentrated into sludge.
  5. Sludge Treatment: The concentrated sludge undergoes further treatment to reduce its volume and stabilize it:
    • Dewatering and Thickening: Reducing the water content to minimize sludge volume.
    • Anaerobic Digestion: May be employed for additional volume reduction and energy recovery.
  6. Disinfection: Post-MBR process, the treated water may require disinfection to eliminate any remaining pathogens:
    • Common methods include chlorination, ultraviolet (UV) radiation, or ozonation.
  7. Effluent Discharge or Reuse: Finally, the treated water, now meeting stringent quality standards, can be:
    • Discharged: Safely into water bodies like rivers or oceans.
    • Reused: For various non-potable applications such as irrigation, industrial processes, or toilet flushing.


Advantages of MBR Technology

Sewage wastewater treatment plants equipped with MBR technology offer numerous benefits:

  1. Compact Design: Requires less space compared to conventional systems.
  2. Higher Treatment Efficiency: Achieves superior contaminant removal.
  3. Improved Water Quality: Produces high-quality effluent suitable for various reuse applications.
  4. Reduced Footprint: More efficient land use.
  5. Potential for Water Reuse: Facilitates sustainable water management practices.

However, it’s important to note that MBR systems demand advanced operation and maintenance due to their sophisticated membrane components. Our team at DEW Projects and Chemicals is dedicated to providing comprehensive support to ensure optimal performance and longevity of these systems.

Tailored Solutions for Your Needs

The specific design and operation of a sewage wastewater treatment plant with MBR technology can vary based on several factors:

  1. Plant Scale: The size and capacity requirements.
  2. Local Regulations: Compliance with regional environmental standards.
  3. Incoming Wastewater Quality: Characteristics and volume of the wastewater.

At DEW, we tailor our MBR solutions to meet the unique needs of each client, ensuring efficient and sustainable wastewater treatment that aligns with local requirements and environmental goals.

Embracing advanced technologies like the Membrane Bioreactor is crucial in our collective effort to address water scarcity and pollution. At DEW, we are proud to lead the way with innovative, efficient, and sustainable wastewater treatment solutions. Our MBR technology not only enhances the quality of treated water but also supports the responsible stewardship of water resources. Together, we can pave the way for a cleaner, more sustainable future.
