Response surface methodology (RSM) and artificial neural network (ANN) have been used to develop predictive models for simulation and optimization of reverse osmosis (RO) desalination process. Sodium chloride aqueous solutions were employed as m[...]texto impreso
García Payo, María del Carmen ; Essalhi, M. ; Khayet Souhaimi, Mohamed | Elsevier B. V. | 2010-02-01Poly(vinylidene fluoride-hexafluoropropylene), PVDF-HFP, hollow fiber membranes were prepared by the dry/wet spinning technique using different copolymer concentrations in the dope solutions ranging from 17 to 24 wt.%. All the spinning parameter[...]texto impreso
Khayet Souhaimi, Mohamed ; Cojocaru, C. ; García Payo, María del Carmen | Elsevier B. V. | 2010-04-01Flat-sheet poly(vinylidene fluoride-co-hexafluoropropylene), PVDF-HFP, membranes have been prepared using the phase inversion technique based on fractional factorial design. Combined effects of polymer and additive (polyethylene glycol, PEG) con[...]texto impreso
For the first time, a mathematical model is presented to validate the hydrophobic/hydrophilic composite membrane concept in membrane distillation (MD). This mathematical model aims at providing the optimal characteristics of both hydrophobic and[...]texto impreso
Arribas, P. ; García Payo, María del Carmen ; Khayet Souhaimi, Mohamed ; Gil, L. | Elsevier B. V. | 2020-03-15Membrane technology is becoming increasingly important to solve the global water scarcity problem because it allows an efficient, economic and environmental friendly treatment of water. However, the long-term use of a filtration membrane is limi[...]texto impreso
Islam, Md Akhtarul ; Hossain, Mohammad Shahedul ; García Payo, María del Carmen ; Khayet Souhaimi, Mohamed ; Ulbricht, Mathias | Elsevier B. V. | 2020-10-15A comprehensive methodology has been developed for treating Gas Liquid Displacement (GLD) porometry data with a flow model called Weber model (WM) describing mixed Poiseuille-Knudsen flow regime. The model has been applied in two options: i) con[...]texto impreso
High consumption of process water and water scarcity has motivated industry to reuse their wastewater. Membrane processes are vital to produce water for reuse from dyeing baths in the tanning industry. In this regard, synthetic dye was recognise[...]texto impreso
Nanofiltration polyester thin-film composite membranes have been prepared by interfacial polymerization using commercial polyethersulfone membrane support. Different monomer bisphenol A (BPA) concentrations in the aqueous solution and various in[...]texto impreso
Novel composite membrane distillation membranes were prepared by blending the hydrophilic polysulfone with hydrophobic surface modifying macromolecules (SMMs). Three different types of SMMs were tested. These SMMs were synthesized and characteri[...]texto impreso
A numerical model of non-isothermal pervaporation was developed to investigate the development of the velocity, concentration and temperature fields in rectangular membrane module geometry. The model consists of the coupled Navier-Stokes equatio[...]texto impreso
texto impreso
Two different types of hydrophobic surface modifying macromolecules (SMMs) were synthesized and characterized for fluorine content, average molecular weight and glass transition temperature. The synthesized SMMs were blended into polyetherimide [...]texto impreso
Abu Seman, M. N. ; Khayet Souhaimi, Mohamed ; Bin Ali, Z. I. ; Hilal, N. | Elsevier B. V. | 2010-06-15Nanofiltration polyethersulfone membrane has been modified by means of UV-initiated graft polymerization technique using the weakly acidic monomer acrylic acid and the immersion method. Different UV-irradiation times and acrylic acid concentrati[...]texto impreso
The experimental design and response surface methodology (RSM) have been used to develop predictive models for simulation and optimization of nanofiltration modified membranes by UV-initiated graft polymerization technique. The objective is to p[...]texto impreso
Both the conventional method of experimentation, in which one of factors is varied maintaining the other factors fixed at constant levels and the statistically designed experimental method, in which all factors are varied simultaneously are carr[...]
