Membrane Distillation Crystallization Hybrid Process for Zero Liquid Discharge in QAFCO Plant
(
Qatar University Press
, 2021 , Poster)
Qatar fertilizer company (QAFCO) is one of the world’s largest single site producer of ammonia and urea with production capacity of 12,900 metric tons per day. Currently, QAFCO faces major challenges in terms of water ...
Simultaneous CO2 treatment and blue energy generation from wasted industrial streams
(
Qatar University Press
, 2021 , Poster)
In the last decade, there has been an increased global need for finding bright solutions to tackle industrial wastes and emissions release. Herein, this work explores the utilization of a compact Reverse Electrodialysis ...
Lithium capture in seawater reverse osmosis (SWRO) brine using membrane-based capacitive deionization (MCDI) system
(
Qatar University Press
, 2021 , Poster)
Lithium-battery based industries including vehicles, electronics, fusion and thermonuclear, consume lithium rapidly, which raises the need for developing a lithium recovery system. Lithium global market consumption in 2016 ...
Facile and Novel LiAlO2 Film Electrodes for Energy Efficient Li recovery from Seawater Reverse Osmosis (SWRO) Brine
(
Qatar University Press
, 2021 , Poster)
Concentration of Li in seawater is too low at 0.17 ppm despite its high content altogether with a reported 230 billion tons. Hence, seawater is not a practical source to recover Li from; Li is largely extracted by solar ...
Tandem osmotic engine based on hydrogel particles with antipolyelectrolyte and polyelectrolyte effect fuelled by both salinity gradient modes
(
MDPI
, 2021 , Article)
In this study, we propose a new approach to attain energy by salinity gradient engines with pistons based on hydrogels possessing polyelectrolyte and antipolyelectrolyte effects in a tandem arrangement, providing energy ...
Sanitation and dewatering of human urine via membrane bioreactor and membrane distillation and its reuse for fertigation
(
Elsevier
, 2020 , Article)
Source separation and recovery of human urine have often been proposed as an effective way to achieve a more sustainable waste-to-resource cycle. Its high density of available macronutrients (N–P–K) in urine makes it an ...
Pyrite (FeS2)-supported ultrafiltration system for removal of mercury (II) from water
(
Springer
, 2021 , Article)
This study investigated the Hg(II) removal efficiencies of the reactive adsorbent membrane (RAM) hybrid filtration process, a removal process that produces stable final residuals. The reaction mechanism between Hg(II) and ...
Theoretical insight into effect of cation–anion pairs on CO2 reduction on bismuth electrocatalysts
(
Elsevier
, 2020 , Article)
This study presents theoretical insight into the mechanism of the CO2 reduction reaction (CO2RR) to formic acid (HCOOH) on Bi (012) surfaces in the presence of alkali metal cations (M+: Cs+, K+, and Li+) and/or halide ...
Effect of Fe/N-doped carbon nanotube (CNT) wall thickness on CO2 conversion: A DFT study
(
Elsevier
, 2020 , Article)
Many researches on CO2 adsorption using carbon nanotubes (CNTs) have been actively studied, but experimental and theoretical studies on CO2 conversion are still in demand. In particular, the effect of CNT wall thickness ...
A review on lithium recovery using electrochemical capturing systems
(
Elsevier
, 2021 , Article Review)
Resource recovery from natural reserves is appealing and Li extraction from different brines is in the forefront. Li extraction by membranes is reviewed in the literature much more than electrochemical processes. However, ...
