0.05um PVDF Hollow Fiber MBR Sludge Treatment Hollow Fiber Membrane Module

Pore Size 0.05um MBR Membrane Elements for Sludge Treatment with PVDF material 

    Membrane bioreactor(MBR) is the new wastewater treatment system that the organic combination of membrane separation technology and biological treatment technology.Using the membrane separation equipment entrap activated sludge and solid in aerobic tank.Therefore the concentration of activated sludge (MLSS) and sludge age (SRT) will increase 2 ~ 4 times in the system, the relative hydraulic retention time(HRT) can be greatly reduced, large particles and difficult to degrade in the process tank can also be continuous reaction and degradation, so the membrane bioreactor by membrane separation technology to strengthen the biological response function.MBR system has been developed in the recent twenty years, with the improvement of membrane manufacturing technology and the accumulated experience of our companys long-term application , MBR process has become a very mature technology and will attract worldwide attention in the environmental protection industry.

Advantages of membrane bioreactor (MBR)
 •Microbe concentration can increase 2 ~ 4 times, biochemical efficiency increased by 20 ~ 40%;
 •Shorten the hydraulic retention time, extend the sludge (organic macromolecules colloidal particles) residence time;
 •The secondary sedimentation tank (sst) can be removed;
 •Water pure and transparent ;
 •Sludge cleaning cycle is long;
 •Simple operation can be automatically controlled;
 •The service life of hollow fiber membrane can reach more than 3 years

Hydrophilic treatment and operation mode of the MBR membrane element 

        If the customers buy the hydrophobic MBR membrane element, for hydrophilic treatment before using, treatment method is using the 95% of the industrial alcohol to immerse about 15 minutes, and then rinse with water . If not use immediately after the hydrophilic, should be sealed packaging to keep membrane wet.

 

 Prevent to block the membrane hole and cleaning 

       Through the aeration system to produce bubbles and water flow, to make the membrane silks shake and clean. At the same time ,using the intermittent operation mode,, can prevent membrane pore to block, and its possible that the system has the long-term stable operation.When the system is operating, keeping stable flow, by the pressure gauge to read operation pressure,working negative pressure -0.01 ~ -0.05MPa,when the operating pressure is more than -0.05MPa, need to clean the MBR membrane element.
