1、 Equipment name: hollow fiber ultrafiltration membrane element (built-in type)

2、 Specification and model: hdnuf-8040

3、 Equipment brand: Wenzhou Haineng wzhdn

gd55光大彩票4、 Product Description:

According to the different forms of ultrafiltration membrane structure, it can be divided into internal pressure type and external pressure type. The above membrane adopts internal pressure, and the internal type can be directly installed into the membrane shell for use. The service life is generally about 2-3 years. If it is replaced, it is only necessary to pull it out of the membrane shell for replacement. Hydantoin hollow fiber ultrafiltration membrane is made of PVC, PVDF, PP and other materials

5. Design parameters:

1. The above fluxes were all measured at 25 ℃, 0.15 MPa;

2. Features:

(1) Excellent oxidation resistance

Generally speaking, the anti pollution performance of membrane in the application process is a permanent concern, and the chemical stability of membrane material greatly affects the anti pollution performance of ultrafiltration membrane. Polyvinylidene fluoride (PVDF) material has the most excellent chemical stability, and its resistance to oxidants (sodium hypochlorite, etc.) is more than 10 times that of polyethersulfone, polysulfone and other materials. In water treatment, microbial and organic pollution is often the main cause of irreversible fouling, while oxidant cleaning is the most effective way to restore the flux. At this time, polyvinylidene fluoride (PVDF) material shows its advantages.

(2) High strength

By using the self-developed formula, the tensile strength and compressive strength of Qianding ultrafiltration membrane are greatly improved compared with the same membrane, so it is easier to adapt to the harsh environment and get high-strength cleaning conditions.

(3) Large flux and high filtering accuracy

The initial flux of the membrane can reach 300L / m2 / h, and the filtration precision can reach 0.03 μ m at the same time of ensuring large flux, which can get better water under various influent conditions.
