Unbiodegradable soluble COD removal from industrial wastewater by a hybrid moving bed biofilm reactor

Carucci A., Cappai G., Camedda C., Erby G., Puggioni G., (Corresponding) Milia S., Tocco G.
Topic: 
Wastewater treatment
In this study, plastics industry wastewater (PIWW) characterized by high total and soluble chemical oxygen demand (tCOD and sCOD, up to ~2200 and ~1500 mg/L, respectively) and remarkable unbiodegradable soluble COD (usCOD, 508±224 mg/L, 31±14% of tCOD) concentrations was treated at laboratory scale...Read more

POLLUTANT PHOTO-NF REMEDIATION OF AGRO-WATER

(Corresponding) Romanos G., Falaras P., Markellou E., Georgaki I., Kizis D., Karanasios E., Anagnostopoulous C.
Topic: 
Water treatment
The agro-food industry is the main manufacturing industry in Europe, representing 14% of the total turnover and accounting for approximately 1.8% of Europe’s total water use. The absence of effective wastewater management approaches can lead to potential ecological ramifications including...Read more

TiO2/CoFe2O4/Ag NANOCOMPOSITES FOR PHOTOCATALYTIC REDUCTION OF WATER POLLUTANTS UNDER UV AND SOLAR LIGHT

(Corresponding) Falaras P., Ibrahim I.
Topic: 
Water treatment
Novel ternary catalysts TiO2/CoFe2O4/Ag with variable ferrite content were synthesized, characterized and used for the photocatalytic reduction of Cr+6 pollutant, under UV and visible light illumination. Both TiO2 and CoFe2O4 were synthesized using the sol-gel method followed by hydrothermal...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

Photocatalytic Removal of Pesticides Present in Agro-industrial Water Effluents

Arfanis M., Theodorakopoulos G., Anagnostopoulos C., Georgaki I., Liappis K., Romanos G., Markellou E., (Corresponding) Falaras P.
Topic: 
Wastewater treatment
Pesticide residues accumulated in agricultural wastewaters constitute a potential risk for the environment and the human health. Hence, focused actions for their elimination are of high priority for both the industry and national authorities. This work evaluates the effectiveness of the...Read more

Photocatalytic degradation of magenta effluent from the printing industry with composite catalyst

(Corresponding) Kerkez D., Pucar Milidrag D., Bečelić-Tomin M., Gvoić V., Kulić Mandić A., Leovac Maćerak A., Tomašević Pilipović D.
Topic: 
Wastewater treatment
Water pollution is one of the most current problems related to human life and survival. The high degree of pollution of the human environment is contributed, among other things, by the discharge of industrial wastewater into rivers, among which wastewater from the graphic industry is of great...Read more

Removal of phosphate ions and Pb (II) from synthetic water matrices using “green” synthesized zero valent iron

Tomašević Pilipović D., Jokić Govedarica J., (Corresponding) Kerkez D., Leovac Maćerak A., Slijepčević N., Gvoić V., Bečelić-Tomin M.
Topic: 
Water treatment
In this paper, phosphates and lead were chosen as the priority pollutant, because their increased concentrations in water can be caused by the release of various untreated effluents and thus can cause serious damage to the environment. Nano zero valent iron synthesized by leaves, In addition to...Read more

Occurrence and potential accumulation of pharmaceuticals in agricultural soils treated with wastewater under real-world environmental conditions in Cyprus

Beretsou V., Iakovides I., Nika M., Gkotsis G., Christou A., Thomaidis N., (Corresponding) Fatta-Kassinos D.
Topic: 
Emerging pollutants
Due to water supply shortages that result from climate change, urbanization, regional droughts and pollution, treated wastewater (TWW) is commonly used to irrigate agricultural land in arid and semi-arid regions. Compared to aquatic systems, contaminants of emerging concern (CECs) only scarcely...Read more

Quantitative target screening and soil bioavailability assessment as tools to assess risks associated with wastewater reuse for irrigation

Beretsou V., Nika M., Manoli K., Lundy L., Thomaidis N., Revitt M., (Corresponding) Fatta-Kassinos D.
Topic: 
Emerging pollutants
Multi-residue analysis of various classes of contaminants of emerging concern (CECs) present in wastewater, along with improvements in analytical methodologies, may allow for future application of promising wastewater tracers, thus providing wastewater treatment plant (WWTP) operators and...Read more

Characterization of Natural Organic Matter and Disinfection By-products Formed After Chemical Disinfection of Water

(Corresponding) Postigo C., (Corresponding) Andersson A., Mourad H., Bastviken D., Gonsior M., Schmitt-Kopplin P., Gago-Ferrero P., Ahrens L., Ahrens L., Wiberg K.
Topic: 
Emerging pollutants
Chemical disinfection of water has been commonly applied to protect public health from waterborne infectious diseases. Chemical disinfectants are strong oxidants that react with the building blocks or alter the metabolism of pathogenic organisms, killing them as the final consequence. These...Read more
