Technical introduction
BENED-MBR（Biology Enhance Nitrification &Denitrification- Membrane Bioreactor）Technologies are our company based on traditional A / O and membrane bioreactor (MBR) process, combined with autonomous intellectual wastewater treatment process with automated control technology. The technology has the characteristics of small coverage, strong impact load, good treatment effect, less sludge production, low energy consumption.
Technical characteristics
● Unique holiday mode control technology
In the operation of the sewage station, the BEND-MBR process encountered a holiday for a long time without water, the system can automatically enter the holiday mode according to the regulatory pool level, and the system fan will run intermittently, and the system fan will automatically invest nutrition. Pharmaceutical, to ensure the state of active sludge, very beneficial to quickly return to the working state after the sewage treatment system, ensuring good operating conditions and water quality. Relevant patent information is as follows:

● Large proportional hydraulic circulation system：
The Bend-MBR process uses a unique hydraulic circulation to improve equipment, using air as a driving force, combined with a special hydraulic structure, and forms high efficiency and energy-saving air solemet. It has the characteristics of a large proportion of reflow, allows the sludge return flow rate to 20-40 times the water flow, and only the excess air volume of the aeration fan, saves the excess air volume in the fan selection, and achieves the purpose of energy conservation. .
There are two main proportional sludge reflux cycles, one is diluting into the water, so that high concentrations of nitrogen phosphorus or toxic substances in the inlet are sharply decreased, reducing the poison of microbial in the system; second, to create a stable growth for microorganisms The environment is extremely impact resistance.

● Package design
The Bend-MBR process adopts integrated structure, and the units of different processing functions are concentrated in the same bioreactive pool, such as biological phosphorus, denitride, aeration zone, separation zone (MBR), even sludge concentrate pools. In the same reaction tank, this can save a large amount of pool, footprint, and pipeline, more importantly, the process itself combines the above-described different process units, and conveys the overall performance and coordination of processes.
The BEND-MBR process integration structure enables simultaneous nitrification and denitration function in the system, and since the membrane separation of MBR, high sludge concentration, the treatment efficiency of nitrogen phosphorus and organic matter is greatly improved, so that the system processing efficiency is high Small area and less residual sludge emissions.
Application field
● Hi-nitrogen organic wastewater treatment such as pharmaceutical, resin, food processing
● Nitrogen phosphorus emission project reverse osmosis system before wastewater treatment
● Water in sewage
● Old sewage treatment system transformation
