      Membrane bioreactor (MBR) is attracting widespread attention around the world as a new water treatment technology that protects the earth's limited water resources and precious environment.　　

      In addition to reducing the environmental load by improving the quality of wastewater treatment, MBR systems are also widely used in wastewater reuse. In order to solve the problem of water scarcity, wastewater reuse activities using MBR technology are being carried out extensively around the world. The MBR membrane has the characteristics of high water permeability, excellent chemical resistance, high-strength hollow fiber membrane, and easy maintenance and management. It can be applied to upgrade sewage treatment facilities of various sizes. As a leading company in MBR technology for Kangnovo Environment, a partner of Mitsubishi Chemical in Japan, we will continue to focus on the increasingly mature water regeneration business activities.

 

MBR process features

◆Compact structure and small foot space. In the MBR process, the secondary sedimentation tank and sand filtration system are eliminated under the same condition of effluent, and the functions of biodegradation and sludge water separation are realized in one reaction tank.

◆High treatment efficiency and good effluent quality. The concentration of nitrifying bacteria is maintained in the reactor, so the nitrification efficiency is high, and the ammonia nitrogen effluent can reach less than 5mg/L;

◆The amount of residual sludge is small. The higher sludge concentration in MBR can keep the sludge load low while the volumetric load is high, and the sludge proliferation is controlled.
◆Easy to realize automation, convenient operation and management;

◆The turbidity of the effluent can reach less than 3NTU.

MBR membrane features

◆High water permeability
Developed a hollow fiber membrane made of high-throughput PVDF to achieve high water permeability.

◆Excellent drug resistance
Because the membrane material uses PVDF resin, chemical resistance and chemical aging are small, it can be used for a long time.
◆High-strength hollow fiber membrane
Due to the high mechanical strength, the membrane is not easy to break, and the structure used makes it difficult to mix suspended solids (SS, etc.) in the treatment water.
◆Easy maintenance and management
Due to the use of highly resistant PVDF resin, maintenance cleaning and recovery cleaning achieve good cleaning results.
