Adapting the use of Fe3O4 nanoparticles in large-scale water treatment facilities
(2014)Magnetite nanoparticles were produced by the chemical co-precipitation of iron sulfates at alkaline conditions and were tested as a Cr(VI) adsorbent from water. Batch adsorption experiments showed a high removal efficiency, ... -
Analytical studies assessing the association between extreme precipitation or temperature and drinking water-related waterborne infections: A review
(2015)Determining the role of weather in waterborne infections is a priority public health research issue as climate change is predicted to increase the frequency of extreme precipitation and temperature events. To document the ... -
Antiflooding prevention, protection, strategic environmental planning of aquatic resources and water purification: The case of Thessalian basin, in Greece
(2010)In the E.U. following the old 5th Environmental Action Program (EAP) of 1994 and the new 6th EAP for the sustainable development in 2001, we confront the strategic management problem of aquatic resources at the regional ... -
A computational tool for the estimation of the optimum gradient magnetic field for the magnetic driving of the spherical particles in the process of cleaning water
(2017)The use of magnetic nanoparticles for cleaning potable water from heavy metals is a novel technique. Suitable magnetic fields are imposed in order to separate magnetic nanoparticles from the water main stream. A numerical ... -
Developing THMs' predictive models in two water supply systems in Greece
(2020)Disinfection is a very significant water treatment process for drinking water safety, as it inactivates pathogens from drinking water. However, disinfection-by-products (DBPs) are formed which are accused of contributing ... -
Differential effect of hydroxen peroxide οn toxic cyanobacteria of hypertrophic mediterranean waterbodies
(2022)Cyanobacterial blooms have been known since ancient times; however, they are currently increasing globally. Human and ecological health risks posed by harmful cyanobacterial blooms have been recorded around the world. These ... -
Economical and social aspects: Evaluation of incorporation potential in municipal wastewater reuse procedure in Greece
(2006)It is the objective of this study to evaluate the incorporation potential of economic and social factors in municipal wastewater reuse procedure, aiming at determining whether it is worthwhile for a municipality to construct ... -
Evaluation of standardized scored inspections for Legionnaires' disease prevention, during the Athens 2004 Olympics
(2006)The study was designed to determine the contribution of standardized scored inspections implemented during the Athens 2004 Pre-Olympic and Olympic period, in assessing the presence of Legionella spp. in water sites. ... -
Exhaled nitric oxide as a marker of chlorine exposure in young asthmatic swimmers
(2019)Background: Swimming is recommended for people with asthma. However, the inevitable exposure to chlorine and its disinfectant byproducts in indoor swimming pools could be responsible for bronchial inflammation and asthma ... -
Fluid structure and system dynamics in nanodevices for water desalination
(2016)Nanofluidic applications are currently being investigated in use for water treatment systems as a power efficient and effective means of removing undesirable substances from drinking or sea water. A detailed study of liquid ... -
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 ... -
Irrigation of radish (Raphanus sativus L.) with microcystin-enriched water holds low risk for plants and their associated rhizopheric and epiphytic microbiome
(2020)Microcystins (MCs) are toxins produced during cyanobacterial blooms. They reach soil and translocated to plants through irrigation of agricultural land with water from MC-impacted freshwater systems. To date we have good ... -
Isolation and characterisation of a Sphingomonas strain able to degrade the fungicide ortho-phenylphenol
(2016)BACKGROUND: Ortho-phenylphenol (OPP) is a fungicide used in fruit packaging plants for the control of fungal infestations during storage. Its application leads to the production of large wastewater volumes which according ... -
Micromixing efficiency of particles in heavy metal removal processes under various inlet conditions
(2019)Water quality problems are a persistent global issue since population growth has continually stressed hydrological resources. Heavy metals released into the environment from plating plants, mining, and alloy manufacturing ... -
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 ... -
