Polymeric and ceramic membranes in three-phase catalytic membrane reactors for the hydrogenation of methylenecyclohexane
This work investigates the hydrogenation of methylenecyclohexane using catalytic membrane reactors. Flat polymeric (PVDF) and tubular ceramic (γ-Al2O3) membranes were prepared and the hydrogenation catalyst, palladium, was deposited into their porous structure. Characterisations wer ...

... of crossflow microfiltration experiments were used: inorganic * Al2(SO4)3 and organic * PRAESTOL. The experiments were carried out on a tubular ceramic microfiltration membrane with nominal size of pores 0.1 mm at various operating parameters. Preliminary tests were performed before crossflo ...

Fabrication of a silica ceramic membrane using the aerosol flame deposition method for pretreatment focusing on particle control during desalination
... membranes ranged from 6.5 to 8.0 µm. Polystyrene particles with sizes higher than 7 µm were almost completely removed by the synthesized ceramic membranes; however, no removal for humic acids was measured with the ceramic membranes tested. A new method, AFD, was developed to fabricat ...

... cost. Iron is often added as effective catalyst in the abovementioned AOP. In this study, a 5 kDa molecular weight cut-off (MWCO) ultrafiltration ceramic membrane (TAMI Industries, France) is tested to directly retain iron species from water. The influence of transmembrane pressure, solution pH ...

Effect of N2-back-flushing in multichannels ceramic microfiltration system for paper wastewater treatment
The ceramic microfiltration system with periodic N2-back-flushing was operated for treating paper wastewater discharged from a company making toilet papers by... was operated for treating paper wastewater discharged from a company making toilet papers by recycling milk or juice cartons. Two kinds of alumina membranes with 7 channels used here for recycling paper wastewater. The optimal N2 filtration time for HC04 membrane with 0.4µm pore size was lower valu ...
