Types and applications of MBR membrane modules
1. Introduction to MBR membrane components
MBR is a new way to treat sewage by combining activated sludge with membrane technology. In the MBR system, the membrane module is important for separating pollutants and microorganisms from the activated sludge mixture. It lets only the clean liquid pass through after treatment. Membrane modules come in two main types: hollow fiber and flat.
2. Hollow fiber membrane module
Hollow fiber membrane modules contain a large number of hollow fiber membranes. The outside of these fiber membranes has tiny holes that stop pollutants and germs but let water molecules go through. Hollow fiber membrane modules have the following characteristics:
Large membrane area, small volume, small footprint
High mechanical strength and good anti-pollution performance
Low operating pressure and low energy consumption
Easy to clean and maintain
People commonly use hollow fiber membrane modules in sewage treatment, industrial wastewater treatment, and recycled water treatment.
3. Flat membrane module
The flat membrane module consists of multiple layers of flat diaphragms. The surface of the diaphragm has a small porous structure. Features of flat membrane modules include :
Large membrane area, small volume
Diaphragm is easy to replace
Cleaning and maintenance are relatively simple
Suitable for treating water with high suspended matter content
Industrial wastewater treatment, food processing wastewater treatment, and other fields commonly use flat membrane modules.
4. Membrane module selection
When selecting MBR membrane modules, you need to consider the following aspects4:
Incoming water quality
Processing power requirements
Floor space restrictions
operating cost budget
Later maintenance requirements
Hollow fiber membrane modules and flat membrane modules both have pros and cons. Choose the best one based on your specific needs. Different membrane module manufacturers produce products with varying materials and performance. It is important to evaluate and compare these differences based on your specific needs.
The MBR membrane module is a key part of the membrane bioreactor system. Its performance impacts the quality of the wastewater output and how well the system operates. The correct selection of suitable membrane components is crucial to ensure the stable operation of the MBR system.
