Development of novel thin film composite reverse osmosis membranes for desalination
Qiblawey H.; Kumar H.; Nasser M.; Benamor A.; Al-Ghouti M. ( American Institute of Physics Inc. , 2019 , Conference Paper)Microporous Polyetherimide (PEI) membranes were prepared by wet phase inversion at different temperatures. The thin film composites (TFC) of polyamide on microporous PEI were prepared using meta-Phenylenediamine (MPD) and ... -
Effect of concentration of calcium and sulfate ions on gypsum scaling of reverse osmosis membrane, mechanistic study
Ashfaq M.Y.; Al-Ghouti M.A.; Da'na D.A.; Qiblawey H.; Zouari N. ( Elsevier Editora Ltda , 2020 , Article)In seawater reverse osmosis, membrane scaling is one of the major issues affecting its widespread application in the desalination industry. In this paper, the effect of concentration of calcium and sulfate ions from 20 to ... -
Effective removal of phenol from wastewater using a hybrid process of graphene oxide adsorption and UV-irradiation
Al-Ghouti M.A.; Sayma J.; Munira N.; Mohamed D.; Da'na D.A.; Qiblawey H.; Alkhouzaam A.... more authors ... less authors ( Elsevier B.V. , 2022 , Article)The focus of this work is the removal of phenol from water by graphene oxide (GO) nanoparticles, prepared by two different methods, through a hybrid adsorption?UV-irradiation process. The GO1 and GO2 were prepared using ... -
Enhancement of flocculation and shear resistivity of bentonite suspension using a hybrid system of organic coagulants and anionic polyelectrolytes
Shamlooh M.; Rimeh A.; Nasser M.S.; Al-Ghouti M.A.; El-Naas M.H.; Qiblawey H.... more authors ... less authors ( Elsevier B.V. , 2020 , Article)In this study, the influence of the hybrid coagulation-flocculation system on the flocculation and shear resistivity of bentonite suspension has been investigated. Two short-chained coagulants, polyamine and polyDADMAC, ... -
Experimental measurements and modelling of viscosity and density of calcium and potassium chlorides ternary solutions
Arshad M.; Easa A.; Qiblawey H.; Nasser M.; Benamor A.; Bhosale R.; Al-Ghouti M.... more authors ... less authors ( Nature Research , 2020 , Article)Measured viscosity and density data for ternary aqueous solutions of CaCl2 and KCl are presented at temperatures between 293 and 323�K with 5�K increment. A modified Jones?Dole was introduced by adding extra terms and ... -
Investigating the effect of temperature on calcium sulfate scaling of reverse osmosis membranes using FTIR, SEM-EDX and multivariate analysis
Ashfaq M.Y.; Al-Ghouti M.A.; Da'na D.A.; Qiblawey H.; Zouari N. ( Elsevier B.V. , 2020 , Article)Membrane fouling is one of the major hurdles in widespread use of seawater reverse osmosis (SWRO) in desalination industry. There are various factors that affect the inorganic fouling or scaling of Reverse osmosis (RO) ... -
Laundry wastewater treatment using ultrafiltration under different operating conditions
Ashfaq M.Y.; Qiblawey H. ( American Institute of Physics Inc. , 2018 , Conference Paper)The laundry wastewater of one of the hospitals in Qatar was selected and studied. It was found that hospital laundry is releasing considerable amount of wastewater i.e. 1800 - 2500 liters/cycle while washing 40 - 50 kg of ...
