Mobile Stand-Alone MBR Membrane Bioreactor Wastewater Treatment Integrated System Technology

Membrane Integration and System Integration

Each membrane technology has specific performance characteristics and application scopes, effectively addressing certain separation challenges. Integrating various membrane processes can optimize separation performance, achieving results unattainable by standalone membrane technologies. For example, the integration of UF, EDR, and RO in seawater desalination or dual membrane processes in advanced wastewater treatment and recovery can produce superior outcomes.

Combining Membrane and Traditional Separation Techniques

To extract products from raw materials, reuse wastewater, or recover valuable components and resources from wastewater, it is often necessary to combine conventional unit operations with membrane technology. This system integration enhances separation processes and maximizes engineering benefits. For instance, the integration of complexation-ultrafiltration-electrolysis technology for heavy metal wastewater treatment follows these steps:

  1. Complexation
    Water-soluble macromolecular polymers complex with heavy metal ions in wastewater.
  2. Ultrafiltration (UF)
    The UF process separates the complexed heavy metals from the wastewater, producing purified water and a concentrated heavy metal complex solution.
  3. Acidification
    The concentrated solution undergoes acidification to dissociate the heavy metal complexes.
  4. Separation and Recycling
    The UF-acidified concentrate separates the complexes from the heavy metals, recycles the macromolecular complexes, and directs the heavy metals to an electrolysis unit.
  5. Electrodeposition
    The electrolysis unit recovers heavy metals from the permeate through electrodeposition.

Advancements in Membrane Technology Integration

With advancements in membrane technology and expanding application markets, membrane integration and system integration technologies will continue to innovate, further enhancing wastewater treatment applications. The combined use of membrane technologies with traditional methods will optimize separation processes and significantly improve treatment efficiency.
