... is combined with a decrease in separation factor. A possible explanation for this remarkable behaviour is a low degree of three-dimensional Thin ceramic-supported PVA membranes have been prepared by the dip-coating technique. The membranes show high performance in the dehydration of alcohols. For ...
Desalination 200 (2006)

Separation efficiency of ceramic NF membranes manufactured by Tami Industries (Nyons, France) is investigated for the separation of aqueous solutions containing strong inorgani ...
Desalination 240 (2009)

... caused by the interaction of membrane–water contaminants, determining the constant tRO. The tests were conducted using a seven-channel ceramic membrane, cut-off 15 kDa. It has been found that the models adequately characterize both direct UF and the hybrid system, and the calculated... both direct UF and the hybrid system, and the calculated values fit the experimental results. Keywords: Water treatment; Ultrafiltration; Ceramic membranes; In-line coagulation 0011-9164/09/$– See front matter © 2009 Elsevier B.V. All rights reserve ...
Desalination 239 (2009)

Nanoscale iron oxide particles were synthesized and deposited on porous alumina tubes to develop tubular ceramic adsorbers for the removal of arsenic, which is an extremely toxic contaminant even in very low concentrations. In addition, its natural presence... of arsenic and may provide a valuable solution to the groundwater quality issue in Latin America. Keywords: iron oxide; arsenic removal; ceramic membranes 1. Introduction Arsenic contamination is a serious threat for human health, especially given that its natural incidence in groundwater is ...

... and expensive desalination processes. To improve thermal, chemical and physical resistance of these membranes, research is now focused on ceramic membranes and hydrophobic ones in particular. The technique used to desalinate water is the Air Gap Membrane Distillation (AGMD), which is mor ...

... microfiltration, and the hybrid process coagulation– sedimentation–microfiltration. In the membrane filtration process 19-channnel ceramic membranes manufactured by Orelis (France) were used. Simulated water containing humic acids in an amount of 20 and 30 mg/l was also used. Fou ...

... through the paper that this pretreatment enhances significantly the permeate flux of whey when cross-flow ultrafiltered through a 50 kDa tubular ceramic membrane both in total recycle and continuous diafiltration mode. For modelling purposes, a resistances in series model was applied to explain the... with time. A pretreatment procedure has been proposed for the clarification of acid whey in order to enhance the permeate flux through ceramic membranes. Its effectiveness was tested employing a 50 kDa tubular membrane in cross-flow operation. This process was able to remove fouling agents but di ...

... formulae is not allowed by the current European legislation. The purpose of this study was to evaluate the potential use of a 50 kDa tubular ceramic membrane in the production of goat milk permeates with a reduced content in protein, while recovering the whole oligosaccharide fraction. The... the minimum number of membrane modules needed to achieve a required recovery of oligosaccharides. Keywords: Goat milk; Oligosaccharides; Ceramic membranes; Dynamic modelling 1. Introduction Among other well-known properties, human milk highlights for its high content of complex fucosylated an ...
