Adsorptive batch and biological treatments of produced water: Recent progresses, challenges, and potentials
( Academic Press , 2021 , Article)Produced water is responsible for the largest contribution in terms of waste stream volume associated with the production of oil and gas. Characterization of produced water is very crucial for the determination of its main ... -
Comparison GIS-Based interpolation methods for mapping groundwater quality in the state of Qatar
( Elsevier B.V. , 2021 , Article)Groundwater (GW) quality deterioration is one of the main water security issues in Qatar. GW in Qatar is over-exploited for agriculture activities that caused saltwater intrusion in the coastal areas and some inland GW. ... -
Improving properties of thin film nanocomposite membrane through polyethyleneimine intermediate layer: A parametric study
( Elsevier B.V. , 2021 , Article)In this work, the polyethyleneimine (PEI)-interlayered thin film nanocomposite (iTFN) membranes were developed by establishing graphene oxide (GO)-incorporated polyamide (PA) layer atop PEI-coated polysulfone (PSf) substrate ... -
Study of bacterial interactions in reconstituted hydrocarbon-degrading bacterial consortia from a local collection, for the bioremediation of weathered oily-soils
( Elsevier B.V. , 2021 , Article)To enhance the process of bacterial remediation of weathered hydrocarbons, the area of Dukhan, Qatar, was considered as a model for weathering processes. Self-purification by indigenous hydrocarbon-degrading bacteria showed ... -
Potential for native hydrocarbon-degrading bacteria to remediate highly weathered oil-polluted soils in Qatar through self-purification and bioaugmentation in biopiles
( Elsevier B.V. , 2020 , Article)Petroleum-derived contamination events constitute a unique environmental issue in the arid areas because of the weathering processes, accentuated due to harsh conditions and representing the main origin of failure of ... -
