Dreamem® Reinforced Hollow Fiber(PVDF)

MBR hollow fiber

DREAMEM has the membrane which is making by NIPS technology, however it forms full- sponge like micro-structure. Based on modefied PVDF materials, the hollow fibers of DREAMEM possess strong hydrophilic and anti-fouling properties. As you can see, the MBR membrane of DREAMEM exhibits a microstructure of fully spongy pores.

SEM of DREAMEM MBR Hollow Fiber

For MBR membrane in microfiltration, there are two main types, one with woven mesh as support layer, and the typical brand is GE (USA), while the other without woven mesh, and the typical brand is Memstar (Singapore). We generally refer to the former as reinforced MBR membrane and the latter as homogeneous MBR membrane.

In industrial wastewater treatment, it will makes MBR membrane prone to breakage and rupture if there is no support layer when in aeration. There is no doubt that this will increase the O&M cost of the project and also affect the normal operation of the project if the hollow fiber is damaged in a large area.

The MBR membrane of DREAMEM, which the support layer and hollow fiber are integrated to form an inseparable "I-I" microstructure.

Dreamem® Antifouling Fomula

Membrane fouling has been one of the hindrances to the development of ultrafiltration technology and an important issue that needs to be addressed urgently. In water treatment, 48.6% of membrane fouling problems are caused by microorganisms such as bacteria. These problems lead to a significant decrease in the water flux and separation performance of the membranes, requiring regular and continuous chemical cleaning or replacement, which seriously affects the service life of the membranes and increases the cost of use.

To modify PVDF material with the latest nano-antibacterial materials, DREAMEM has created a series of durable anti-fouling membrane products. It can not only reduce the cleaning frequency and the consumption of chemicals, but also slow down the decline of membrane flux and ensure the long-term service life. The patented formula of DREAMEM makes the antibacterial rate of every hollow fiber reach to 99.9999%.
