MBR Membranes

 AMESTEC MBR-DBM Series Membrane Bio-reactors 

 

Membrane Bio-Reactor (MBR) is a new type of wastewater treatment system that combines membrane micropore separation technology with biological treatment technology. The membrane filtration system replaces terminal secondary sedimentation tank of the traditional biological treatment technology, utilizes the membrane separation and interception performance to increase the activated sludge concentration of the biochemical system, prolongs the biological reaction time, increases the organic load of biological treatment, and thereby reducing the sewage treatment facility floor space, effectively reducing the amount of excess sludge.

Based on years of innovative development and investment, AMESTEC membrane products (MBR-DBM series) has produced on a large scale. In the continuous development process, AMESTEC MBR products have a large number of installation and actual operation cases, which are widely used in sewage treatment plant upgrades, high-concentration wastewater treatment, landfill leachate treatment and other fields. 

 

 

 

AMESTEC MBR Technology

 

AMESTEC MBR-BR series membrane bio-reactor adopts the thermally induced phase separation process to prepare PVDF reinforced hollow fiber membrane, which has large flux, chemical washing resistance and so on. At the same time, its mechanical strength is greatly improved, and the design of uniform membrane filament distribution and module device is combined, thereby reducing sludge deposition and the risk of filament break. The elements, membrane box, aeration and water collection are optimally integrated into a complete filtration system, and the operating energy consumption is reduced. The membrane pool area is saved by 1/3 compared with the conventional MBR, and the installation and maintenance are more convenient.

AMESTEC MBR-BR series membrane bioreactor employs intermittent vacuum draw, supporting uninterrupted gas scrubbing operation mode to filter and produce water, periodic physical and chemical cleaning methods to remove pollutants to ensure long-term stable operation of membrane system.
