[Threshold Flux and Membrane Fouling Analysis of the Hybrid Pre-ozonation and CNTs Membrane Modification Process].

Polyvinylidene fluoride (PVDF) hollow fiber ultrafiltration membranes were modified with carbon nanotubes (CNT). Hybrid pre-ozonation and CNT modification were investigated by experimentally manipulating the ozonation process, threshold flux, and membrane fouling. The results showed that the threshold fluxes of the unmodified membrane and hybrid process were 45 L·(m·h) and 81 L·(m·h), respectively.

[Effect of Hybrid Process of Pre-ozonation and CNT Modification on Hollow Fiber Membrane Fouling Control].

Polyvinylidene fluoride (PVDF) hollow fiber ultrafiltration membranes were modified with carbon nanotube (CNT). Combined with the ozonation process, the effect of the hybrid pre-ozonation and CNT modification on fouling alleviation was investigated. The impacts of CNT loading mass and ozone dosage on the variation of flux and antifouling ability of the membrane modules were evaluated.
