The effect of fiber length, intrinsic gas permeance on the pressure profile at the permeate side of membrane are also discussed. The pressure profiles serve as a first indication for the design of hollow fiber membrane module.Tuan-Anh Nguyen...
where J is the permeate flux (L·m−2·h−1), q is the membrane permeate volume (L), S is the effective surface area of membrane (m2), t is the time (h). Removal efficiency (R, %) of organic pollutant by the VMT membrane and/or Co@VMT/PMS system can be calculated as fol...
These OPMs are effective in allowing oxygen to permeate while suppressing the permeation of moisture into the ALB systems and would prevent the evaporation of electrolyte solvents. For nickel form, the application in OPMs was inevitably limited by the large pores. Therefore, a PANI (polyaniline): ...
The same set of single channel conductance measurement and pore size calculation performed onCh-C4in triplicate gives an average conductance value of 188.5 ± 9.6 pS (Supplementary Figs.21–28) and an average pore size of 0.94 ± 0.03 nm in diameter. A representative I-V curve...
A valve is placed after the membrane module to permit pressure control. Temperature also needs to be monitored. Parameters such as permeate filtration rate and quality as function of system pressure and recovery can be measured over time. Pilot-plant experiments are also carried out in order to ...
The model takes into account the permeate pressure variation inside the fiber. In the special case of negligible permeate pressure drop, the model yields a simple analytical solution for membrane area calculation that eliminates the numerical integration step required in existing methods. Laboratory ...
In the present paper, a theoretical examination is made of the retentate recycle to the permeate stream, which was verified experimentally as an effective method for enriching the less permeable component in the retentate stream using hollow fiber membrane permeators. The concentration of the less pe...
The fact that the maximum pressure on the Membrane Fouling Simulator (MFS) is limited to 5 bars, excludes the possibility of permeate production in the cell. However, this has been validated not to influence the representativeness of the MFS. A comparison study of the MFS and spiral wound me...
Radical attack on the membrane is deemed as the key reasons for membrane chemical degradation: oxygen molecules permeate from cathode side to anode side and oxygen of anode side can reduce the Pt catalyst to form HOO∙ and HO∙ radicals, and this would further result in significant ...
wherecpandcoare the concentrations of the molecule in the permeates and original solutions. For the mixed molecules separation experiments, 5 ml aqueous solution contained 100 mg l−1Cu2+, 4 mg l−1RB, and 100 mg l−1Cyt. c was used as the feed solution. First, th...
