MBR membrane module(PVDF) & MBR system
Hangzhou Kaijie Membrane Separation Technology Co., Ltd.
PVDF
kaijie Membrane use a variety of composite materials and special nano materials to form of the network structure technology,successfully developed the PVDF+PET hollow fiber membrane, It has good pollution resistant, large flux, inside and surface of membrane are smooth,high strength, easily cleaning and flux recovery,etc.
|
Kaijie membrane modules have two outstanding advantages: 1.Superstrength: Enhanced PVDF hollow fiber membrane,the material for the PVDF+PET lined woven tube,and successfully solve the problem that fracture of ordinary PVDF hollow fiber membrane in the process of using. The so-called "Never broken membrane", In addition,because of film has good intermiscibility with braided tube,at the same time to join the special nano materials and adhesives,and overcomes the defects that the practical application of membrane cortex is easy to fall off. 2.Larger flux The PVDF membrane of Kaijie membrane company with permanent hydrophilicity,and the specific nano materials can effectively uniformly dispersed in the membrane system, and exert the nano effect, to increase the membrane flux and strength.By adding nanoparticles, membrane module can greatly improve the hydrophilicity of the membrane surface, and significantly increase the membrane flux and the anti-pollutaion ability. |

Note:1.If use KJDF4090A, MBR membrane reactor height is 2000 mm, when the same membrane modules assembly, the width and length are the same, the design flux according to one piece of membrane design flux X quantity of membrane.
2. Design flux of membrane system in the form: The lower limit value for industrial wastewater design flux, flux upper limit for the design of domestic sewage.
