Variation of specific cake resistance according to size and fractal dimension of chemical flocs in a coagulation-microfiltration process A theoretical model to predict the porosity and specific resistance of cake layer was developed for better understanding a coagulation-microfiltration system for drinking water production. The model was based on fractal theory and incorporated intra-floc and inter-floc porosities as well as cake col Desalination 199 (2006)
Experimental analysis of a gel layer in dead-end ultrafiltration of a silica suspension* Unstirred dead-end ultrafiltration of a silica suspension was studied using a fully retentive membrane. A constant pressure filtration approach was used to analyze steady-state flux data. The effects of operating conditions such as applied pressure and bulk concentration on specific resistance, thic Desalination 172 (2005)
Synthesis and characterization of polyaryl blend membranes having different composition, different covalent and/or ionical cross-linking density, and their application to DMFC In this contribution, different ionomer blend membrane types which show high proton conductivity, thermal stability, and good direct methanol fuel cell (DMFC) performance, are presented: (1) Covalently cross-linked blend membranes from polyaryl sulfinates and polyaryl sulfonates where the sulfinate Desalination 147 (2002)
Untitled N-vinyl-2-pyrroldinone was grafted by the UV-irradiation process onto the porous surface of poly(vinyl chloride) (PVC) membrane to increase the surface wettability and to decrease the adsorptive fouling. The graft yield of the modified PVC membrane was maximum at 5 min UV exposure time and 20 wt% aq Desalination 146 (2002)
