Efficiency of Arsenic Removal from Water Using Fe-Modified Biochar from Date-Palm-Leaves Combined with Spectral Induced Polarization (SIP) Monitoring
Siddiq O., (Corresponding) Tawabini B., Kirmizakis P., Kalderis D., Ntarlagiannis D., Soupios P.
Topic:
Water treatment
In this study, lab-scale column batch adsorption experiments were conducted to demonstrate the efficiency of Iron-modified Biochar (Fe-BC) produced from date-palm leaves at 500oC to remove arsenic (As) from contaminated water. The As removal capacity were monitored by both chemical analysis and...Read more

Hydro-stratigraphy, Aquifer Characterization and Physiochemical Analysis of District Dera Ghazi Khan Punjab, Pakistan.
(Corresponding) Ullah H., Khalid P., Shah G., Mashwani S., Shafiq W., Din Z.
Topic:
Water treatment
The study area is located in the arid section of Punjab province, Pakistan. The accessibility of freshwater is the main problem in this zone. The area is approximately flat and there are alluvial deposits up to 800 m. Groundwater is not fit for health because of its salinity. Hence, it is essential...Read more

Silver decorated TiO2/g-C3N4 nanocomposites for photocatalytic elimination of water pollutants under UV and artificial solar light
Ibrahim I., Belessiotis G., Kaltzoglou A., Katsaros F., Salama T., (Corresponding) Falaras P.
Topic:
Water treatment
TiO2/g-C3N4/Ag nanocomposites were prepared and used as highly efficient photocatalysts. TiO2 nanoparticles were first prepared using a sol-gel process, and titania herostructures with varying amounts of graphitic carbon nitride (g-C3N4) were created using a hydrothermal technique. Following...Read more

Synthesis of Fe3O4-Ag Nanocomposite and Their Performance as Surface Modifiers for TiO2 Membranes in Treating Oily Wastewater
Aboulella A., Wadi V., Naddeo V., Banat F., (Corresponding) Hasan S.
Topic:
Water treatment
Membrane technology has shown extraordinary performance in treating oily wastewater. Yet, more research is focused towards enhancing the performance of the separation process. In this work, Fe3O4-Ag composite nanoparticles (NPs) were synthesized using the co-precipitation technique and applied on...Read more
This study investigated the removal of arsenite (As(III)) and arsenate (As(V)) in aqueous solution using iron-coated pomelo peel (ICPP). Batch adsorption experiments were performed to evaluate the effects of initial pH values (2.0–10), contact time (1–1440 minutes), initial concentration (0.05–5 mg...Read more

Nutrient Removal from Stormwater using Australian Native Plants in Constructed Floating Wetland
(Corresponding) Nuruzzaman M., Anwar A., Sarukkalige R.
Topic:
Water treatment
Stormwater pollution causes excessive nutrient influx to rivers and lakes, which can trigger algal bloom and subsequent damages to the freshwater ecosystem. Constructed Floating Wetland (CFW), a cost-effective technology, uses aquatic plants in a hydroponic system to strip nutrients from stormwater...Read more
Functionalized iron oxide nanocomposite ultrafiltration membranes for water-in-oil emulsion separation
Wadi V., Ouda M., Naddeo V., Banat F., (Corresponding) Hasan S.
Topic:
Water treatment
Removal of emulsified water in oil (w/o) emulsions are the most challenging compared to free water and dissolved water emulsions. Emulsified w/o cannot be removed by conventional techniques such as settling tanks, oil skimmers, floatation and magnetic technologies. Membrane technology is a highly...Read more

Kinetics study of the MO adsorption and photocatalytic degradation using an effectively engineered HF photocatalyst
(Corresponding) Theodorakopoulos G., Katsaros F., Papageorgiou S., Romanos G.
Topic:
Water treatment
In this study, copper decorated photocatalysts (Degussa P25), were shaped in the form of ceramic hollow fibers (HFs) and their photocatalytic properties were investigated using Methyl Orange (MO), a prototype anionic pollutant. The abatement of the dye was tested in dark and under UV irradiation by...Read more

Synthesis of Fe3O4/Carbon Quantum Dots Hybrid for Efficient Removal of Congo Red Dye from Aqueous Solution
(Corresponding) Zourou A., Axarli V., Falara P., Ntziouni A., Kordatos K.
Topic:
Water treatment
During the past decades, the release of toxic pollutants into aquatic environment has continuously increased due to rapid industrialization and civilization. The presence of organic dyes, such as Congo Red (CR), can be dangerous to both human and aquatic life. Therefore, their removal is an...Read more
