Treatment of Sand Using Microbial-Induced Carbonate Precipitation (MICP) for Wind Erosion Application
(
American Society of Civil Engineers (ASCE)
, 2018 , Conference Paper)
Microbial-induced carbonate precipitation (MICP) has been used to improve soil properties for different geotechnical applications. This research focuses on evaluating the use of MICP for the wind erosion application. The ...
Isolation, differentiation and biodiversity of ureolytic bacteria of Qatari soil and their potential in microbially induced calcite precipitation (MICP) for soil stabilization
(
Royal Society of Chemistry
, 2018 , Article)
Biomineralization plays a key role in modifying the geological properties of soil, thereby stabilizing it against wind erosion, especially in areas characterized by harsh weather and harsh soil (calcareous and arid); i.e. ...
Identification and overcome of limitations of weathered oil hydrocarbons bioremediation by an adapted Bacillus sorensis strain
(
Academic Press
, 2019 , Article)
Because of the high production of oil and gas in Qatar, the likelihood of oil spill occurrence is most probably susceptible to happen. Contaminated soil treatment is very expensive. Cost effective mechanisms are investigated ...
Characterization of the extracellular polymeric substances (EPS) of Virgibacillus strains capable of mediating the formation of high Mg-calcite and protodolomite
(
Elsevier B.V.
, 2019 , Article)
The origin of dolomite –a common mineral in the geological record– is the subject of an ongoing debate. Among different hypotheses, it has been proposed that extracellular polymeric substances (EPS) excreted by microbes ...
Removal of boron from water using adsorbents derived from waste tire rubber
(
Elsevier Ltd
, 2019 , Article)
In the current study, the remediation of boron by adsorption from water was investigated at different pH values, initial boron concentration, adsorbent dosage and particle size using adsorbents prepared from waste tire ...
An integrated approach for produced water treatment using microemulsions modified activated carbon
(
Elsevier Ltd
, 2019 , Article)
In this study, the physical and chemical characterization of produced water was done followed by treatment through sand filtration coupled with activated carbon microemulsion modified activated carbon techniques. The results ...
Removal of Toxic Elements and Microbial Contaminants from Groundwater Using Low-Cost Treatment Options
(
Springer Science and Business Media Deutschland GmbH
, 2021 , Article)
Purpose of Review: This paper reviews various low-cost treatment techniques such as adsorption, permeable reactive barrier, and biological techniques for the simultaneous removal of chemical and microbial contaminants from ...
Hydrogeochemical characterization and quality evaluation of groundwater suitability for domestic and agricultural uses in the state of Qatar
(
Elsevier B.V.
, 2020 , Article)
This study aims to investigate the groundwater (GW) quality in Qatar to be utilized in domestic and agricultural uses. The integrated physiochemical analysis along with hydrochemical faces analysis, geochemical modeling, ...
Functionalization of reverse osmosis membrane with graphene oxide and polyacrylic acid to control biofouling and mineral scaling
(
Elsevier B.V.
, 2020 , Article)
The polyamide reverse osmosis (RO) membrane was modified with graphene oxide (GO), followed by polymerization of acrylic acid (used as an antiscalant) for the reduction of both biofouling and mineral scaling. After ...
Effect of concentration of calcium and sulfate ions on gypsum scaling of reverse osmosis membrane, mechanistic study
(
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 ...
