... gas permeability improves because of the increasing free volume and/or temperature of the membranes. The permeability coefficients of CO2 for a cellulose acetate (CA) membrane were measured at 25°C using a hand-made apparatus which can irradiate a microwave (2,450 MHz) to the membrane. Both th ...

Effect of production conditions on morphology and permeability of asymmetric cellulose acetate membranes
Membranes are widely used in wastewater treatment. In this study, cellulose acetate (CA) (Mw = 52,000) was mixed with polyethylene glycol (PEG) (Mw = 400) as an additive in N-methyl-2-pyrrolidone as a solvent. The phas ...

Desalination of brackish water from Tunisian Sahel using composite polymethylhydrosiloxane–cellulose acetate membranes
Composite cellulose acetate (CA) based membranes having a hydrophobic top layer made of polymethylhydrosiloxane (PMHS) were prepared with the aim of desalination o ...

Treatment of seafood processing wastewaters by ultrafiltration–nanofiltration cellulose acetate membranes
... organic (COD of 20,000–35,000 mg.L−1) and inorganic (TDS of 30–40 g.L−1) load. These seafood effluents were subjected to treatment with cellulose acetate (CA) membranes synthesised according to the phase inversion process. Two preparation parameters, i.e. polymer concentration in the dop ...

Development of reverse osmosis desalination membranes composition and configuration: future prospects
The most common reverse osmosis (RO) membranes which attained the stage of economic application in desalination plants are made of cellulose acetate (CA) or polyamide (PA), in either hollow fiber (HF) or spiral wound (SW) configurations. The first application problem of CA membrane i ...

Change of the performance properties of nanofiltration cellulose acetate membranes by surface adsorption of polyelectrolyte multilayers
Surface modification of nanofiltration cellulose acetate (CA) membranes was carried out by alternating layer-bylayer deposition of acidic chitosan (CHI) and sodium alginate (ALG) as the cationi ...

... was fabricated with an inner layer of poly(vinylidene ﬂuoride) (PVDF) via thermally induced phase separation (TIPS), and an outer layer of cellulose diacetate (CA) via non-solvent induced phase separation (NIPS). The intermediate-treatment using dimethyl formamide (DMSO) between the two layer ...
