During the six-day exhibition period of the First Import Expo, a total of 1 million people visited the Expo, with the largest passenger flow exceeding 200,000 in a single day.The audience produced a large amount of domestic sewage, which would cause serious water pollution if not treated.The MBR integrated equipment produced by hutaiwater is used to treat domestic sewage in the Expo, which solves the problem of water pollution.

Due to the filtration of membrane in the integrated MBR sewage treatment equipment, many beneficial microorganisms cultivated by the system are completely intercepted in the bioreactor. The bio-treatment efficiency is high, no chemicals are needed and the operation cost is low. At the same time, the effluent with turbidity less than 1 can be obtained by membrane filtration. The effluent is of good quality and can be reused directly.

As a Hollow Fiber Membrane Production Enterprise，Hutai water Provide high quality MBR products has the following characteristics:

（1）Permanent hydrophilic modification of PVDF membrane materials to achieve pollution resistance and flux optimization；

（2）The diaphragm aperture is 0.03-0.1 um, the effluent quality is stable, and the turbidity is less than 1 NTU;

（3）The operation and maintenance are simple, and the service life can reach more than 10 years.
