Khayet Souhaimi, Mohamed ; Qtaishat, M. ; Matsuura, T. ; Khulbe, K. C. | Taylor & Francis Inc | 2009-05This study aims to compare the effect of host hydrophilic polymer on novel hydrophobic/hydrophilic composite membrane characteristics and desalination performance by direct contact membrane distillation (DCMD). Two different polymers are used fo[...]texto impreso
The stoichiometric ratio for the synthesis components of hydrophobic new surface modifying macromolecules (nSMM) was altered systematically to produce three different types of nSMMs, which are called hereafter nSMM1, nSMM2, and nSMM3. The newly [...]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
A Monte Carlo (MC) simulation model is developed to study heat and mass transfer through hydrophobic membranes applying direct contact membrane distillation (DCMD) process. In this study, the membrane pore space is described by a three-dimension[...]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
Khayet Souhaimi, Mohamed ; García Villaluenga, Juan Pedro ; Godino Gómez, María Paz ; Mengual Cabezón, Juan Ignacio ; Seoane Rodríguez, Benjamín ; Khulbe, K. C. ; Matsuura, T. | Elsevier | 2004-10-15Dense flat-sheet membranes were prepared from poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) using the casting solvents chloroform and 1,1,2-trichloroethylene. X-ray diffraction, tapping mode atomic force microscopy (TM-AFM), and contact angle stu[...]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 [...]
