6000 To 12000mg/L MBR Filter Membrane

Product Specification

Membrane Bioreactors For Wastewater Treatment with PVDF material

The MBR process generally consists of a membrane separation module and a bioreactor, and the membrane assembly replaces the secondary sedimentation tank for solid-liquid separation. Since the membrane can trap all the biomass in the reactor, long sludge age and high suspended solids concentration can be obtained, which is beneficial to the growth of slow-growing nitrogen-fixing bacteria and nitrifying bacteria, and simultaneous nitrification and anti-inversion can be realized without aeration. Nitrification enhances the nitrification capacity of activated sludge, and membrane separation maintains a low FöM, making the excess sludge yield much less than the activated sludge process, and the system operation is more flexible and stable.

Process characteristics:

• The concentration of activated sludge can reach 6000-12000mg/l, and the effect of removing organic matter is enhanced.
• Effectively intercept small, slow-growing nitrifying bacteria, greatly improving ammonia nitrogen removal rate
• Membrane filtration pore size reaches 0.05 microns, directly retaining bacteria, can be directly reused
• Long sludge discharge period, low sludge yield, reducing sludge treatment costs
• Saves the second settling tank and saves land; it can save 50% of the floor space compared with the traditional processing system.
• low energy consumption, simple cleaning and low operating cost

• Membrane water treatment technology has the characteristics of high efficiency and energy saving. , To some certain extent, the popularization and application coverage of membrane separation technology reflects the level of energy use and environmental protection of a country and region. It is also a guarantee means for sustainable development of society. Therefore, The strategic position of membrane separation technology is very prominent.

  The key point to membrane water treatment is the microporous structure and surface properties of the membrane material. Scientists around the world proceed from the selection of materials and the optimization of the membrane-making process in order to prepare a membrane separation materials with excellent performance.

  Accessing a membrane have a good practical value should depend on the following few points:

• High retention rate and high water permeability rate;
• Strong resistance to physical, chemical and microbial attack;
• Flexible and sufficient mechanical strength;
• Resistant to high temperature
• Excellent anti-pollution;
• Good resistance to chlorine and other oxides;
• Long service life and withstand wide range of pH value;
• Low operating pressure
• Easy to store and transport;
• Convenient preparation and industrialized production;
• Dry and wet reversible.

• Obtaining membrane separation materials with excellent separation selectivity and higher permeability has always been the goal pursued by membrane scientists and engineers. Through research on hollow fiber membranes from the selection of membrane-forming materials, optimization of process parameters, surface post-treatment, and design of membrane modules in scientific research institutions all over the world in recent decades, the overall performance of hollow fiber ultrafiltration membranes and microfiltration membranes has been improved greatly.
