A novel alternative to free oil remediation and recovery: Foamy absorbents designed from low molecular paraffinic waste
( Elsevier , 2022 , Article)This study focuses on preparing porous, hydrophobic, and oleophilic hydrocarbon-based foams applicable for removing free oils from water surfaces. Paraffinic waste material generated during industrial production of low-density ... -
A predictive model for the assessment of the temperature polarization effect in direct contact membrane distillation desalination of high salinity feed
( Elsevier B.V. , 2014 , Article)Temperature polarization is one of the major sources responsible for flux drop in membrane distillation systems due to the reduction in the driving force across the membrane. The present study offers a predictive model ... -
Effect of operational parameters on distillate flux in direct contact membrane distillation (DCMD): Comparison between experimental and model predicted performance
( Elsevier B.V. , 2014 , Article)Membrane distillation (MD) is a thermally driven process where hydrophobic membranes are used to separate saline hot feed solution and cold stream of water and allow water to evaporate due to temperature difference. This ... -
Evaluation of cellulose triacetate hollow fiber membrane for volume reduction of real industrial effluents through an osmotic concentration process: A pilot-scale study
( elsevier , 2021 , Article)The current article tackles the challenge of reducing wastewater volumes generated from the gas industry. A forward osmosis (FO) pilot unit, deployed as osmotic concentration (OC) process without the draw solution (DS) ... -
Evaluation of polymeric adsorbents via fixed-bed columns for emulsified oil removal from industrial wastewater
( Elsevier Ltd , 2022 , Article)Polymeric adsorbents (PAs) have been gaining increased attention for application in industrial wastewater (WW) treatment. However, most studies on evaluating PAs specifically for emulsified oil removal are currently limited ... -
Evaluation of pretreatment and membrane configuration for pressure-retarded osmosis application to produced water from the petroleum industry
( Elsevier , 2021 , Article)Pressure-retarded osmosis (PRO) is a promising membrane technology for harnessing the osmotic energy of saline solutions. PRO is typically considered with seawater/river water pairings however greater energy can be recovered ... -
Field evaluation of membrane distillation technologies for desalination of highly saline brines
