Energy efficiency of direct contact membrane distillation
(
Elsevier B.V.
, 2018 , Article)
Membrane distillation (MD) is a promising technology due to its ability to function using low temperature differences and low-quality heat sources, thus allowing it to operate on solar or waste heat. The flux and energy ...
Experimental measurements and modelling of viscosity and density of calcium and potassium chlorides ternary solutions
(
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 ...
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 ...
Enhancement of flocculation and shear resistivity of bentonite suspension using a hybrid system of organic coagulants and anionic polyelectrolytes
(
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, ...
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. ...
Activation of kaolin with minimum solvent consumption by microwave heating
(
Mineralogical Society
, 2014 , Article)
A kaolin clay was activated with 1.0 M H2SO4 solution at minimum liquid to solid ratio (L/S) using microwave heating. The optimum experimental conditions for activation were L/S ratio 3.0 mL 1 M H2SO4 per gram kaolin, ...
Potential application of microalgae in produced water treatment
(
Desalination Publications
, 2018 , Article)
The current study examines pollutant removal efficiency from the produced water of a local petroleum industry by five different local microalgae species. The five microalgae strains Monoraphidium, Chlorella, Neochloris, ...
Lead (Pb) bioaccumulation and antioxidative responses in Tetraena qataranse
(
Nature Research
, 2020 , Article)
Lead (Pb) is the second most toxic metal on Earth and is toxic to humans and other living things. In plants, Pb commonly inhibits growth when it is at a concentration in the soil of 30�mg/kg or more but several Pb tolerant ...
Effective removal of phenol from wastewater using a hybrid process of graphene oxide adsorption and UV-irradiation
(
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 ...
Utilization of nano-olive stones in environmental remediation of methylene blue from water 03 Chemical Sciences 0306 Physical Chemistry (incl. Structural)
(
Springer
, 2020 , Article)
Background: The use of agricultural waste as a low-cost adsorbent for the removal of hazardous methylene blue (MB) from aqueous solution was investigated. In this research, the potentiality of using black nano olive stones ...
