MBR membrane


With the improvement of wastewater discharge standards and the decrease of membrane cost and energy consumption, the MBR process has been enjoying rapid development due to its excellent effluent quality, direct reuse and land saving. The "Water Pollution Prevention and Control Action Plan" is about to be released, will leveraging 2 trillion water market investment, the market fundamentals or usher in a substantial change, MBR as the current fastest growing technology will undoubtedly bring Great opportunity for development. At the same time, due to its large-scale application in urban sewage treatment has just started, the existing urban sewage MBR system, combined with related engineering experience, based on the study of successful cases and technical specifications at home and abroad, summed up the urban sewage treatment project MBR technology Biochemical system design of key technologies is necessary.


Membrane bioreactor (MBR) process system of choice


For urban sewage treatment projects, due to the large scale (generally 1 × 10000m3 / d or more), taking into account the membrane assembly operating environment, sludge concentration control, nitrogen and phosphorus removal of the DO control requirements and reduce energy requirements, Vacuum suction submerged split MBR process are generally used.


Biochemical technology choice

The choice of the form of biochemical systems mainly consider the following aspects: 

① water quality, such as biodegradable organic matter concentration, carbon and nitrogen ratio, carbon and phosphorus ratio; 

② effluent quality requirements, especially for the effect of nitrogen and phosphorus removal, etc. ; 

③ water quality and water fluctuations; 

④ climatic conditions. From the current application of engineering experience point of view, A2O and its deformation enhancement process is the treatment of many applications in the MBR nitrogen and phosphorus removal process the most prominent effect, the operation and management of the most convenient and most stable and reliable category.


RisingSun's MBR membrane is based on PVDF for better chemical stability, stain resistance and mechanical strength. The company uses advanced film-making process, control membrane pore size of 0.1μm, and have a higher water flux and effluent quality. Board with mortise and tenon match, the diaphragm spacing is more stable, without the side plate. Diaphragm installation, can be installed from the top down, can also be installed from the side, not subject to construction site conditions. Laser-engraved diamond-shaped flow channel, with a dedicated umbrella-shaped support structure, the suction pressure distribution, without diversion cloth to reduce the risk of fouling, large board dual outlet design, the water collection faster.
