MBR system aerated wastewater treatment systems

Membrane Bioreactor, referred to as the MBR water treatment technology is a biotechnology and membrane technology combined with efficient biological treatment, membrane bioreactor is a combination of a membrane separation technology and traditional methods of efficient sludge wastewater treatment technology, Since the filtration membrane, biological completely trapped in the bioreactor, to achieve a complete separation of the hydraulic retention time and the sludge age, and so maintain a high MLSS within the bioreactor. Nitrification ability, pollutant removal efficiency.

MBR tanks membrane frame, membrane frame preservative commonly used steel structure. In order to make membrane in the biochemical pool have better water effects, the proposed location in the following sizes designed membrane frame.
membrane frame and biochemical wall from ≥400mm
membrane frame with membrane frame spacing ≥400mm
When using three ways to connect a group of membrane, the effective depth MBR tank is designed to 2800mm - 3000 mm is appropriate.
When using two membrane for connection of a group, the effective depth of MBR tank is designed to 2000mm - 2400 mm is appropriate.
When the MBR for small projects, using a set of effective depth of not less than 1000mm.

MBR membrane features

1. High flux rate, up to 55 LMH (L/m2*H). Asymmetric membrane structure reduces flow resistance, and improves hydraulic properties and permeability;
2. Reinforced PVDF membrane structure for mechanical strength. Membranes are less susceptible to being damaged during the filtration, backwashing or chemical cleaning;
3. Unique anti-fouling design; specific design of aeration nozzles prevents extensive membrane fouling, extending the operation time;
4. Wide range of membrane sizes and configurations for optimal system design;
5. Sealed fiber end design; bottom end of each hollow fiber is sealed; permeate is collected through the top opening preventing the contamination of clean water with sludge and bacteria;
6. Stable operation and long service life.
