Modification of tubular ceramic membranes with carbon nanotubes using catalytic chemical vapor deposition
In this study, carbon nanotubes (CNTs) were successfully grown on tubular ceramic membranes using the catalytic chemical vapor deposition (CCVD) method. CNTs were synthesized at 650°C for 3–6 h under a 120 mL min−1 flow of C2H6 on ceramic membranes impregnated with iron salt. The synthesis procedure was beforehand optimized in terms of catalyst amount, impregnation duration and reaction ...

Treatment of domestic wastewater with an anaerobic ceramic membrane bioreactor (AnCMBR)
In this study, a ceramic membrane with a pore size of 80 nm was incorporated into an anaerobic membrane bioreactor for excellent stability and integrity. Chemical oxygen demand (COD) removal efficiencies by biodegradation reached 78.6 ± 6.0% with mixed liquor suspended solids (MLSS) of 12.8 ± 1.2 g/L. Even though the total methane generated was 0.3 ± 0.03 L/g CODutilized, around 67.4% of it ...

Wastewater treatment using bioreactor with dual functional ceramic membrane
A novel bioreactor including a group of dual functional ceramic membranes was developed and used for wastewater treatment. The ceramic membranes could be used for both aeration and filtration alternately, so fouling to ceramic membrane would be palliated effectively as its dual functions. For 100 days operation, COD removal ratio was 88∼97% for influent COD of 154∼1389 mg/L, and NH4+-N removal ...

Degreasing Liquid Treatment
Degreasing is a necessary step before any other processing in mechanical industry, in the steel industry and generally speaking in the transformation of raw materials. Degreasing is performed with aid of an aqueous solution containing detergents. The detergents emulsify oil present on the material to be treated; for this reason, oil concentration tends to increase in degreasing treatment baths ...

What Is The Difference Between Dead-End Filtration And Cross-Flow Filtration?
Ceramic membrane manufactured by JIUWU HI-TECH is used for liquids separation in a cross-flow filtration way which is different from dead-end filtration. Dead-end filtration means the fluids flow is vertical to the filter surface, and the retained particles rapidly solidify on the surface of the filter to form a so-called filter cake. The pores of the filter are clogged by the filter cake, and ...
