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 ...

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 ...

Evaluation of an emerging water treatment technology: ceramic membranes
Historically, low-pressure membranes (microfiltration (MF) and ultrafiltration (UF)) used in potable water treatment are made of polymers (polysulfone (PS), polypropylene (PP), polyethersulfone (PES), polyvinylidene fluoride (PVDF) etc). Recently, membranes made of ceramic materials (aluminium oxide) have been developed by MetaWater (Japan), Kubota (Japan) and others and is being marketed in the ...

Fabrication of circular shaped ceramic membrane using mixed clays by uniaxial compaction method for the treatment of oily wastewater
Circular shaped ceramic membrane was fabricated using inexpensive mixed clays by uniaxial compaction method and subsequently fired at 900°C. TGA analysis demonstrates that the minimum sintering temperature required to fabricate the membrane is above 800°C. A volume median diameter d(0.5) of the raw material mixture is found to be 2.78 µm. XRD analysis verifies that the membrane undergoes phase ...
