Introduction
The MBR High Quality Integrated Module Bioreactor Membrane (BN90) is a suspended growth-activated sludge system that utilizes microporous membranes for solid/liquid separation instead of secondary clarifiers. The system uses precision filter membranes having pore sizes of 0.1 µ M. MBR treated water can be used for landscaping, toilet flushing, and a variety of other applications.
System flow scheme
The MBR High Quality Integrated Module Bioreactor Membrane (BN90) allow for size reduction of the structures required by up to 70 % and even increase the performance of wastewater treatment plants.
The principle of membrane filtration is based upon the separation of solids suspended in a watery solution by means of a pressure difference. While the water permeates through the membrane, the solids, bacteria and even most viruses are retained on the concentrate side on the membrane surface where they are removed by relative movement.
The MBR system is provided with multiple membrane elements in an integrated membrane module in 2 or 3 stages in an aerobic tank. The MBR systems utilize side-stream cross-flow membrane configuration. The wastewater is filtrated using suction filtration, and the filtered water becomes treated.
Air is supplied from the air diffuser installed on the bottom of the membrane module to prevent sludge from adhering to the membrane surface. Thus, the system can perform stable treatment without getting clogged.
Key Benefit of MBR High Quality Integrated Module Bioreactor Membrane (BN90)
1. High efficiency / Low maintenance
2. Membrane modules are backflushable
3. Easy to clean
4. Yield 60-80% less sludge than conventional system
5. Compact design footprint 75% smaller than conventional
6. Possibility of direct and indirect water reuse
