Product Details

4 inch Ultra-filtration Membrane Module for Pure Water Purification with PVDF material

 

 

1. UF technology introduction
1.1.Ultrafiltration (UF) is a separation principle for screening, with pressure as the driving force to realize
mechanical separation membrane separation process, namely under certain pressure, when the mixed
solution of large molecules or a small molecule solute through the membrane surface, solvent
(e.g., inorganic salt) and small molecule solutes through the membrane, and the solute molecules due
to mechanical filtration membrane as concentrate intercept.


1.2.Ultrafiltration membrane products made by PVDF material
PVDF hollow fiber ultrafiltration membrane has strong anti-oxidation, anti-pollution and good cleaning performance,
which is widely used in various sewage treatment industries
.

 

1.2  Advantages:
a. Good hydrophilic, big water flux;
b. Strong chemical resistance, big rang for PH adaptation;
c. High strength, no broken fiber, long life;
d. Cleaning is simple, flux recovery is good.
