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. ; Essalhi, M. ; García Payo, María del Carmen ; Arribas, P. ; García Fernández, L. | Elsevier Science BV | 2012-02-15A fractional factorial design and a steepest ascent method were applied for possible fabrication of hollow fibers by the dry/wet spinning technique. Seven spinning factors were taken into account. Different concentrations of the copolymer poly(v[...]texto impreso
Khayet Souhaimi, Mohamed ; Essalhi, M. ; Armenta Déu, Carlos ; Cojocaru, C. ; Hilal, N. | Elsevier Science BV | 2010-10-31A solar thermal and photovoltaic-powered reverse osmosis (RO) desalination plant has been constructed and optimized for brackish water desalination. The central composite experimental design of orthogonal type and response surface methodology (R[...]texto impreso
García Payo, María del Carmen ; Essalhi, M. ; Khayet Souhaimi, Mohamed | Elsevier Science BV | 2009-09-15Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) hollow fiber membranes were prepared by the dry/wet spinning technique at different copolymer concentrations from 17 to 24 wt%. All the spinning parameters were kept constant except the[...]texto impreso
Self-sustained electrospun nanofibrous membranes (ENMs) were prepared using the polymer polyvinylidene fluoride (PVDF) and applied for desalination by direct contact membrane distillation (DCMD). Different electrospinning times were considered t[...]texto impreso
A novel theoretical model that considers the gas transport mechanisms through the inter-fiber space of self-sustained electrospun nanofibrous membranes (ENMs) is developed for direct contact membrane distillation (DCMD). The theoretical model in[...]texto impreso
A fluorinated surface modifying macromolecule (SMM) was synthesized and blended into the casting solution of polyetherimide used as host polymer. A composite porous hydrophobic/hydrophilic membrane was prepared by the phase inversion technique i[...]texto impreso
