factor) and permeate flux. In this experiment, five input parameters were surveyed, including trans membrane pressure (TMP), flow and temperature of feed, pH and concentration of wastewater. In this experiment, real wastewater was not used but synthetic...

segment phases and crystallinity of soft segments increase by increase the ether change extender BDA in polymer structure. The soft area of polyurethane polymer is made of Polyol Due to enhancement in free volume, gas permeation increases corresponding...

In this study, the effect of silica nanoparticles on the gas permeation properties of polyether-based

polyurethane membrane was investigated. Polyether-based polyurethane was synthesized by bulk twostep

polymerization of polypropylene...

and permeate flux on operative parameters such as temperature, flow rate, concentration, and pH of feed were studied. Response surface methodology (RSM) has been applied to arrange the experimental layout which reduced the number of experiments and also...

to characterize the CA and CA/silica nanocomposite membranes. Gas permeation experiments showed an increase in the permeability of CO2 from 6.32 to 7.3 barrer and a reduction in the permeability of N2 from 0.18 to 0.09 barrer with the increment in silica content...

In this study, the effects of various solvents on the structure and permeation properties of polysulfone–silica nanocomposite membranes were investigated. Silica nanoparticles were prepared by the sol–gel method through the hydrolysis...
