Comparison between plasma microbubbles and gas-liquid dielectric barrier discharge (DBD) plasma for pollutants degradation in water
Meropoulis S., (Corresponding) Aggelopoulos C.
Topic:
Advanced oxidation processes
This study's main emphasis is the direct comparison between gas-liquid dielectric barrier discharge (GLDBD) and plasma microbubbles (PMB) concerning the kinetics related to the contaminant’s destruction and plasma-activated water composition. As contaminants with different structures,...Read more
Destruction of Perfluorooctanoic acid (PFOA) in water by cold atmospheric plasma
Papalexopoulou K., Ronen A., (Corresponding) Aggelopoulos C.
Topic:
Advanced oxidation processes
Cold atmospheric plasma was investigated as for the remediation of perfluorooctanoic acid (PFOA) contaminated water. The destruction of the highly toxic PFOA is a challenging task since it is a persistent and bioaccumulative chemical causing pollution in waterbodies. In this study, plasma...Read more

Nitrogen & Phosphorous Removal via Anaerobic / Anoxic-Aerobic Processes and Struvite Formation in Mall Wastewater: Performance of Retrofitted Full-Scale Plants
Maceda M., (Corresponding) Rollon A., Sinoy M.
Topic:
CIRCULAR ECONOMY AND BIOECONOMY
With the new standards on nitrogen (N) and phosphorous (P) in wastewater discharges from industrial, commercial and municipal wastewater, there is a need for better wastewater treatment systems. Moreover, with the presence of such N and P in wastewater, struvite formation leading to clogging of...Read more
Effects of High Temperature and Liquid Nitrogen Cooling: A Case Study of granite rocks from Kazakhstan
(Corresponding) Longinos S., Tuleugaliyev M., Begaliyev D., Hazlett R.
Topic:
Renewable energy sources
Cryogenic fracturing using liquid nitrogen (LN2) is a new geothermal well stimulation method to augment porosity, permeability, and overall contact area in Hot Dry Rock (HDR) reservoirs in an environmentally acceptable way, without potential surface or groundwater contamination, formation damage,...Read more

Changes in geomorphic units alter nitrogen fixation in a large lowland tropical river
(Corresponding) Gani M.
Topic:
Ecological effects of environmental change
The present investigation was carried out over 50 km reach, the Padma River of Bangladesh, downstream of the confluence of the Ganges and Brahmaputra rivers. The study area is highly dynamic, with diverse geomorphic units, high rates of bank erosion, and sediment abstraction. Sentinel-2 imagery (...Read more

Synthesis of iron and nitrogen co-doped biochar for the activation of peroxymonosulfate to degrade sulfamethoxazole
Xue Y., Kamali M., (Corresponding) Dewil R.
Topic:
Advanced oxidation processes
In this study, iron and nitrogen co-doped biochar (Fe-N-BC) was synthesized by a facile pyrolysis process of mixed walnut shell, melamine, and iron(III) chloride, and then the biochar (BC), nitrogen-doped biochar (N-BC), and iron-doped biochar (Fe-BC) also were prepared as a control. The Fe-N-BC...Read more
Keywords:
Iron and nitrogen co-doped biochar; peroxymonosulfate; mechanisms; toxicity.
Comparative analysis of two microalgae-bacterial symbiotic association growth in papermill effluent enriched through food waste digestate
Talapatra K., (Corresponding) Ghosh U.
Topic:
Wastewater treatment
New treatment methods are needed to better recycle waste towards the circular economy. Microalgae can be used as an asset to treat effluent and simultaneously produce biofuel. This paper aims to evaluate the growth of microalgae-bacterial symbiotic association in papermill effluent enriched through...Read more
