MBR Membrane Biological Reaction Process with Reinforced PVDF material

MBR Membrane Biological Reaction Process

Features of Membrane Bio-reactor for MBR Membrane System
MBR membrane is a new high-efficiency wastewater treatment process combining high-efficiency membrane separation technology with traditional activated sludge process. It is placed in an aeration tank with a unique structure of MBR flat membrane module after aerobic aeration and biological The treated water is filtered by a pump through a membrane and then withdrawn. It uses membrane separation equipment to trap activated sludge and micro molecular organic matter in the biochemical reaction tank, eliminating the secondary settling tank. The concentration of activated sludge is thus greatly increased, and the hydraulic retention time (HRT) and sludge residence time (SRT) can be controlled separately, while the refractory substances are continuously reacted and degraded in the reactor.
easy to complete automatic control, management and operation are simple.

The membrane module is placed in the reactor, and the filtering liquid is obtained by vacuum pumping or natural siphoning. The cross-flow required for cleaning the membrane is generated by air agitation. Air is added directly below the membrane. The liquid shear force reduces the sedimentation of material on the surface of the membrane, thereby reducing the pollution of the membrane. Integrated membrane bioreactor, the process is a combination of conventional sewage biodegradation technology and membrane separation filtration technology. After the organic sewage is biodegraded, the solid-liquid separation of the sewage is completed by using a microfiltration membrane or an ultrafiltration membrane to achieve purification of the sewage. The function of the membrane module here is to replace the secondary sedimentation tank and sedimentation filtration unit in the conventional sewage treatment process so that the hydraulic retention time and the sludge age are no longer related, and the stability of the affluent and the excellent water quality can be guaranteed. The integrated type has a small footprint and low energy consumption and can be modularly constructed into a series of sewage treatment stations or sewage treatment plants.

Aerobic membrane bioreactors are mainly used in urban and industrial sewage treatment, which can realize the recycling of water resources in urban sewage treatment, and can remove specific pollutants in industry, such as the treatment of industrial oily wastewater.

We,Hangzhou Kaihong Membrane Technology Co.,Ltd, is established on the year of 2003. We specializes in manufacturing UF and MBR membrane modules. We own more than 20 years of experience for the applying of UF and MBR membrane modules. Our products have been used in more than 1000 water treatment plants. We also have more than 2000 customers all over the world.

We have R&D team to develop new products and new separating technology for ourselves. We also have quality controlling system to ensure our products. At present our main products are made of PSF/PP/PVDF. We have hollow fiber membranes and flat sheet membranes for MBR systems. So we can meet different requirements for wastewater treatment and water purification.
