Community structure and activity of a highly dynamic and nutrient-limited hypersaline microbial mat in Um Alhool Sabkha, Qatar
( Public Library of Science , 2014 , Article)The Um Alhool area in Qatar is a dynamic evaporative ecosystem that receives seawater from below as it is surrounded by sand dunes. We investigated the chemical composition, the microbial activity and biodiversity of the ... -
Electrochemical oxidation/disinfection of urine wastewaters with different anode materials
( MDPI , 2019 , Article)In the present work, electrochemical technology was used simultaneously for the deactivation of microorganisms and the destruction of micro-pollutants contained in synthetic urine wastewaters. Microorganisms (E. coli) were ... -
Interaction of seawater microorganisms with scalants and antiscalants in reverse osmosis systems
( Elsevier B.V. , 2020 , Article)In this research, the interactions of seawater microorganisms with scalants (minerals like calcium sulfate) and antiscalants in the reverse osmosis (RO) systems were investigated. The interaction of seawater microorganisms ... -
Investigating the microorganisms-calcium sulfate interaction in reverse osmosis systems using SEM-EDX technique
( Elsevier Ltd , 2020 , Article)Membrane fouling affects the performance of membrane technologies such as reverse osmosis (RO), in water treatments and desalination industries. The membrane fouling is a multifaceted phenomenon and various components of ... -
Isolation, identification and biodiversity of antiscalant degrading seawater bacteria using MALDI-TOF-MS and multivariate analysis
( Elsevier B.V. , 2019 , Article)Seawater reverse osmosis (SWRO) is a commonly used desalination technique owing to its lesser environmental and economic impacts as compared to thermal desalination techniques. Antiscalants are used in SWRO to reduce ... -
Microbial degradation of chlorophenols
( Springer Berlin Heidelberg , 2017 , Article)Chlorophenols (CPs) are hazardous pollutant that are commonly encountered as major constituents of several types of wastewater such as industrial, refinery and pharmaceutical wastewater. They are also exposed to the ... -
Performance Of Chlorella Vulgaris, Neochloris Oleoabundans, and mixed indigenous microalgae for treatment of primary effluent, secondary effluent and centrate
( Elsevier B.V. , 2016 , Article)The objective of this study was to investigate and compare the growth rate and treatment efficiency of Chlorella vulgaris, Neochloris oleoabundans and mixed indigenous microalgae for the removal of organic carbon, nitrogen ... -
Phytoremediation of polluted soils and waters by native Qatari plants: Future perspectives
( Elsevier , 2020 , Article Review)Because pollution is predicted to worsen and sources of quality water for agriculture and other human activities are limited, many countries have been motivated to seek novel water sources. Qatar relies on groundwater and ... -
Potential use of mixed indigenous microalgae for carbon dioxide bio-fixation and advanced wastewater treatment
( AIChE , 2017 , Conference Paper)The potential use of mixed indigenous microalgae (MIMA) as a CO2 capturing technology and treatment process for wastewaters was evaluated at two temperatures ( 25 and 30 C) and different CO2 dosage ( 0%, 5% and 15%). During ...
