Working Principle of MBR Membranes
The working principle of MBR (Membrane Bioreactor) membrane modules is based on membrane separation technology. Under a specific driving force, MBR membrane modules effectively separate various components in a mixed solution. Taking hollow fiber membranes as an example:
Hollow Fiber Membrane Structure: The hollow fiber membranes have a tubular structure with micro-pores on the walls, which can retain activated sludge and most suspended solids, ensuring clear and transparent effluent.
Key Features:
Enhanced Biochemical Efficiency: Microbial concentration can increase 2-4 times, thereby enhancing biochemical efficiency.
Short Hydraulic Retention Time: The system has a short hydraulic retention time, allowing organic macromolecules to remain longer and effectively improving wastewater treatment capacity.
Elimination of Secondary Settling Tank: MBR technology eliminates the need for a secondary settling tank, simplifying the treatment process.
Easy Operation: The system is easy to operate and control.
Long-lasting Membrane Material: Hollow fiber membranes can have a lifespan of over three years, reducing maintenance costs.
Balanced Flow Distribution: Equipped with a balanced flow distribution and control system to ensure stable treatment effects.
Air Cleaning: The membrane modules have air cleaning and diversion devices, reducing maintenance frequency.
Flexible Assembly: The membrane rack design allows for easy assembly, accommodating various installation requirements.
Independent Area Design: The independent design of the biological treatment and membrane separation areas enhances operational flexibility.
Online Backwashing: Features an online backwashing function to reduce membrane fouling and clogging.
Chemical Cleaning: The chemical cleaning process is straightforward, helping to maintain membrane performance.
Applications:
Wastewater Treatment: Suitable for various biochemical wastewater treatments, including industrial and domestic sewage.
Oil-contaminated Wastewater Treatment: Effectively handles oily wastewater to meet environmental discharge standards.
High Sludge Content Wastewater: Processes wastewater with high sludge content, such as that from the pharmaceutical and food industries.
Reclaimed Water Reuse: Can be used for reclaimed water and wastewater recycling, enhancing water resource utilization efficiency.
Ecological Restoration: Applied in ecological restoration and water body remediation, assisting in water quality recovery.
Industrial Wastewater Treatment: Suitable for wastewater treatment in the chemical, pharmaceutical, and other industries.
