Definition Of Membrane Bioreactor MBR
The membrane element in the MBR system replaces the terminal secondary sedimentation tank in traditional biological treatment technology, maintains a high activated sludge concentration in the bioreactor, increases the organic load of the biological treatment system, and uses the excellent filtration performance of the membrane separation system to intercept the Activated sludge and macromolecular organic matter can achieve good sewage treatment effects, opening up a new path for the development of new sewage treatment processes.
Feature & Advantages of MBR Assembly
– Excellent Effluent Quality can be directly reused
– Realize Total Separation of HRT and SRT to get rid of Sludge Expansion or unstable outlet water quality
– Bear Large Shock Load Resistance
– Can Stable Run Under 3000-10000mg/L Activated Sludge Density to reduce Sludge Discharge thus to realize zero sludge discharge
– Has Certain Denitrification And Phosphorus Removal Functions due to prolonging sludge Service Time
– Save 30-50% Mounting Room or Replace Secondary Clarifier
– Can be carry on upgrading with existence pool to save RCC room
– PLC automatic Control All The System
