Preparation of an asymmetric microporous carbon membrane for ultrafiltration separation: application to the treatment of industrial dyeing effluent

Synthesis and characterization of clay-based ultrafiltration membranes supported on natural zeolite for removal of heavy metals from wastewater

“…However, the membrane flux varied from 70 L/h m 2 at 3 bar to 175 L/h m 2 at 7 bar. The increase of the permeate flux with pressure has been reported earlier by several researchers for different nature of ceramic membranes (Bhattacharya et al,2013;Khemakhem et al,2013;Tahri et al,2016).…”

Treatment of textile wastewater using monolayered ultrafiltation ceramic membrane fabricated from natural kaolin clay

“…They found that this synthesis UF membrane displayed rejection of 87.35% and 46.08 % respectively for COD and conductivity, however a high rejection of 95.35% and 99.52% for color and turbidity was observed in the same time. Therefore, it is evident that the membrane elaborated in this study has a characteristics that outperforms other developed UF ceramic membranes.On the other hand,according to Khemakhem and al [39],a low cost phosphate based UF ceramic membrane having a water permeability of 90 L.h -1 .m -2 .bar -1 was developed and applied succesfully to the treatment of textile effluent providing 90% COD removal and a total retention of color.…”

Ultra-dehydration of a reactive epichlorohydrin-containing organic mixture using a defect-free thin carbon molecular sieve composite membrane

“…Moreover, a CMS membrane possesses an anti-swelling property in water-containing mixtures even at elevated temperatures. 31 Indeed, the excellent pervaporation performance and stability of CMS membranes were observed for water/alcohol mixtures (ethanol, methanol, and IPA), 28,[32][33][34][35][36] water/acetic acid, 32 and benzene/cyclohexane. 37 Furthermore, the brittleness of the initial CMS membranes was overcome by depositing a carbon layer on a porous substrate such as alumina and stainless steel.…”
