外压式pvdf中空纤维膜组件

external pressure type pvdf hollow fiber membrane module

特点

characteristic

（1）膜丝均匀分布于6个等面积扇形区域，装填密度高，污水处理效率高；

in membrance modules, the membrances are evenly distributed in six equally sector areas leading to

high packing density and high sewage treatmeat efficiency;

（2）进水端设置导流孔，引导来水均匀进入过滤系统，减少污堵。

the water inlet of membrance  module is set with guide holes for guiding raw water into filtration system

evenly which could reduce fouling;

（3）滤芯独立于外壳，可实现定期更换，降低使用成本；

the filter element of the membrance module is independent of the shell which could realize the exchanging

of the filter element and reduce the cos;

（4）独特的封装工艺，减少膜丝断裂现象，延长使用寿命。

the unique packaging process could reduce the membrance fracture phenomenon and prolong service life.

高抗污染pdvf中空纤维超滤膜

high anti-fouling pvdf hollow fiber ultrafiltration membrane

独创vnips法

the original steam-non-solvent induced phase separation method

膜表面孔径小，开孔率高，孔径均一

small surface pore size,high porosity,mean pore size distribution

抗污能力强，产水量高

strong anti-fouling ability and high water yield

公司生产的高抗污染pvdf中孔纤维超滤膜稳定通常是普通pvdf膜的2倍

the steady water flux of high anti-fouling pvd hollow filber ultrafiltration

membrance is twice as much as the value of nomal pvdf membrance

柔性拉伸工艺

flexible drawing process

拉伸强度高（抗拉强度达4.5mpa以上，使用寿命长）

high tensile strength(the tensile strength reach 4.5mpa,which could prolong service life)
