(2020)In order to provide solutions for the pollution caused by nitrogen-containing wastewater and the shortage of fossil fuels, it is urgent to design highly performing bifunctional catalysts for the urea oxidation reaction ... -
The effect of coagulation on the toxicity and mutagenicity of reclaimed municipal effluents
(2006)The objectives of this work were the assessment of the effectiveness of coagulation on the reclamation of secondary effluents and the evaluation of the quality of reclaimed waters by the examination of their ecotoxic and ... -
Environmental planning in Magnesia prefecture, Greece
(2003)The environmental planning of Magnesia Prefecture is studied in this work, aiming at the assessment of the environmental quality and the determination of the most appropriate objectives and priorities, for the achievement ... -
Growth, grain yield and nitrogen use efficiency of Mediterranean wheat in soils amended with municipal sewage sludge
(2014)The application of sewage sludge (SS) to agricultural land can improve soil fertility and physical properties, and enhance crop production. This field study was conducted for two consecutive growing seasons to investigate ... -
In-situ electrosynthesis of hydrogen peroxide and wastewater treatment application: A novel strategy for graphite felt activation
(2018)Electrochemical synthesis of hydrogen peroxide (H2O2) through O2 electroreduction is an attractive alternative to the currently used anthraquinone process, and highly desirable for green chemical industries and environmental ... -
Inactivation, removal, and regrowth potential of opportunistic pathogens and antimicrobial resistance genes in recycled water systems
(2021)With two thirds of the global population living in areas affected by water scarcity, wastewater reuse is actively being implemented or explored by many nations. There is a need to better understand the efficacy of recycled ... -
Integrated biodepuration of pesticide-contaminated wastewaters from the fruit-packaging industry using biobeds: Bioaugmentation, risk assessment and optimized management
(2016)Wastewaters from fruit-packaging plants contain high loads of toxic and persistent pesticides and should be treated on site. We evaluated the depuration performance of five pilot biobeds against those effluents. In addition ... -
Integrated management of hydroponic wastewater for complete water recycle and cyanobacteria cultivation using an electric conductivity-based tool
(2022)This work presents an integrated management process for hydroponic wastewater (HWW) reuse, by developing an electric conductivity-based tool that calculates recycled nutrient solutions' enrichment requirements and indicates ... -
Isolation, characterization and industrial application of a Cladosporium herbarum fungal strain able to degrade the fungicide imazalil
(2022)Imazalil (IMZ) is an imidazole fungicide commonly used by fruit-packaging plants (FPPs) to control fungal infections during storage. Its application leads to the production of pesticide-contaminated wastewaters, which, ... -
Mixing of Fe3O4 nanoparticles under electromagnetic and shear conditions for wastewater treatment applications
(2022)The ability of heavy metals to accumulate in living organisms, combined with the fact that they are not biodegradable, necessitates an expansion and improvement of the existing water purification methods. An effective ... -
New Electro-Fenton Gas Diffusion Cathode based on Nitrogen-doped Graphene@Carbon Nanotube Composite Materials
