Coal fly ash zeolites as adsorbents for effective removal of heavy metals and dyes from contaminated waters
Zgureva D., (Corresponding) Boycheva S., Behunová D., Václavíková M.
Topic:
Wastewater treatment
Recently, the purification of enormous amounts contaminated industrial, agricultural and municipal waters increases the demands of low-cost and technologically feasible techniques. The application of natural zeolites in wastewater treatment is known from many years. A feasible approach for...Read more

Magnetite nanoparticles activated coal fly ash zeolites with application in waste water remediation
(Corresponding) Boycheva S., Miteva S., Trendafilova I., Zgureva D., Václavíková M., Popova M.
Topic:
Wastewater treatment
The application of zeolites in wastewater treatment is studied long ago but still many unexploited opportunities exist. Recent investigations on natural and synthetic zeolites in water decontamination are focused on the improvement of their adsorption and ion-exchange properties modifying them by...Read more

Radiation-induced degradation products of 2-methyl isoborneol and geosmin: the role of different reactive species
CHRISTOPHORIDIS C., PESTANA C., LAWTON L., (Corresponding) HISKIA A.
Topic:
Water treatment
Gamma radiolysis can serve as an effective method for the degradation of organic water pollutants, due to the production of reactive species, oxidative (OH•, OOH•, O2•-) or reductive (eaq-, H•). The application of scavengers enables the selective production of these species. Our aim was to explore...Read more
Nitrogen co-doped with fluorine on reduced graphene oxide for enhanced electrocatalytic activity and stability for ORR in alkaline fuel cells
Musico Y., Labata M., (Corresponding) Chuang P., Ocon J.
Topic:
Energy technologies and sustainability
Nitrogen co-doped with fluorine on reduced graphene oxide (rGO) was prepared by one-pot hydrothermal treatment method. The scanning electron microscopy (SEM) images and X-ray photoelectron microscopy (XPS) spectra revealed the successful doping of nitrogen and fluorine into the rGO. The Brunauer-...Read more
3D printed lab-scale raceway ponds reactors for photo-Fenton processes
Nasr Esfahani K., Zandi M., Travieso-Rodriguez J., Graells M., (Corresponding) Perez-Moya M.
Topic:
Advanced oxidation processes
Abstract
Raceway pond reactors (RPRs) have been widely used in microalgae mass culture (Acien et al., 2013) and their application for micro pollutant removal in photo-Fenton processes has been recently assessed (Rivas et al., 2015). The main advantages of raceway pond reactors are being low cost...Read more

New evidence of accelerated elimination of an emergent water pollutant by TiO2 assisted photo-oxidation
(Corresponding) FAVIER L., LASLAU A., SIMION A., SESCU A., HARJA M., RUSU L.
Topic:
Advanced oxidation processes
Over the past few years, the presence of the pharmaceuticals and their metabolites in the aquatic environment has become an important public health issue. These molecules are generally released in the aquatic ecosystem through the effluents of conventional wastewater treatment plants which were not...Read more

Water reuse integration in the holistic water cycle
(Corresponding) Adin A.
Topic:
Water and wastewater reuse
Wastewater reclamation and reuse (WRR) is an emerging water generation tool for combating water stress. The objective of this paper is to develop a conceptual approach which will pave the way to WRR sustainable integration in a multi-resources regional or local system. For that purpose, a holistic...Read more

Hybrid zero liquid discharge (ZLD) membrane/chemical process for the treatment of oil sands produced water
Mohammadtabar F., (Corresponding) Khorshidi B., Hayatbakhsh A., (Corresponding) Sadrzadeh M.
Topic:
Wastewater treatment
In this study, the applicability of a hybrid chemical/membrane process for the treatment of the boiler blow-down (BBD) water from steam assisted gravity drainage (SAGD) operation was explored. For the chemical pre-treatment prior to the membrane filtration, another waste stream of SAGD, i.e., ion...Read more

Topic:
Water treatment
As an obstacle against the widespread application of membranes in larger scales, fouling via different materials could cause a severe decline in water permeation. Herein, we fabricated a novel mechanically-stable electro-conductive membrane by simple pressure-assisted laminating of reduced Graphene...Read more
TREATMENT OF SLAUGHTER HOUSE WASTEWATER UTILIZING COGON GRASS (Imperata cylindrica) IN A SUBSURFACE FLOW SYSTEM CONSTRUCTED WETLAND IN ZAMBOANGA CITY, PHILIPPINES
(Corresponding) Flores R., (Corresponding) Adil J.
Topic:
Wastewater treatment
Natural treatment systems are gaining a preference for wastewater treatment as an ecosystem-based adaptation to climate change. This study investigated the performance of a laboratory scale horizontal subsurface flow constructed wetland (SSFCW) planted with cogon grass (Imperata cylindrica) in...Read more
