IMPREGNATED RESINS AS NOVEL SORBENTS FOR REMOVAL OF TOXIC METAL IONS FROM AQUEOUS SOLUTIONS
(Corresponding) Zawierucha I., Nowik-Zajac A., Kozlowski C.
Topic:
Wastewater treatment
The adsorption/solid phase extraction (SPE) processes are the most attractive methods for effective removal of metals ions from different aqueous solutions. In SPE procedure, the choice of appropriate adsorbent is a critical factor to obtain full recovery and high enrichment factor.
For this...Read more

Challenges in biological treatment plants: the approach of zero sludge waste
THEOFANIDIS S., Samiotis G., Bellos D., Pekridis G., Tsioptsias C., (Corresponding) Amanatidou E.
Topic:
Wastewater treatment
The current trend in operation of biological Wastewater Treatment Plants (WWTPs) is the minimization of sludge wastage due to its labor and cost intensive management process. Minimization of sludge can be achieved by increasing the solids retention time (SRT) in a WWTP, up to an almost complete...Read more
REMOVAL OF TOXIC METAL IONS THROUGH POLYMER INCLUSION MEMBRANES CONTAINING MACROCYCLIC LIGANDS AS CARRIERS
(Corresponding) Nowik-Zajac A., Zawierucha I., Kozlowski C.
Topic:
Wastewater treatment
More strict environmental regulations on the discharge of toxic metals require developing various technologies for their removal from polluted streams. The separation of toxic metal ions using immobilized membranes with doped ligands, due to their high selectivity and removal efficiency, increased...Read more

Successful use of UV light driven photocatalytic oxidation for the removal of an emergent water contaminant
SESCU A., FAVIER L., LUTIC D., CIOBANU G., (Corresponding) HARJA M.
Topic:
Water treatment
The discharged pharmaceutical compounds in water have created environmental problems due to their harmful potential at low concentrations. Finding an environmentally friendly treatment process is a real challenge to avoid water contamination. Heterogeneous photocatalysis, can be used for the...Read more
Electrochemical Treatment of Landfill Leachate under Cold Climate Conditions
(Corresponding) Ambauen N., Meyn T., Hallé C., Muff J.
Topic:
Advanced oxidation processes
This study shows that electrochemical oxidation of landfill leachate (LL) is significantly affected by cold temperatures prevailing in Nordic climate areas. As hypothesized, the degradation of common wastewater parameters (TOC, COD) exhibited lower efficiency when low average temperature (13°C) was...Read more

Enhanced of TiO2-Ag photocatalysis performance for removal of methylene blue in presence of acetone
(Corresponding) HARJA M., DUDUMAN NUTESCU C., APOSTOLESCU G., GÓMEZ DE SALAZAR J., GÓMEZ DE CASTRO C., SESCU A., FAVIER L., CIOBANU G.
Topic:
Nanomaterials in the environmnents applications and effects
In the present study, the photocatalytic degradation of methylene blue (MB), using TiO2-Ag synthesized by sol-gel method, as a catalyst under UV light, was studied. The samples synthesized were characterized by SEM, EDAX, FTIR, XRD and TEM. The average size of the particles was 10 nm. Tests were...Read more
According to the latest environmental requirements, zero liquid discharge principle must be considered in all modern manufacturing processes. In principle, solid waste can be achieved only by evaporation plus crystallization, and therefore reverse osmosis is usually applied to decrease the...Read more

Genetic population structure of Scallops going through a rapid population decline in the Eastern Mediterranean
(Corresponding) Metaxatos A., Gazouli M.
Topic:
Marine environment and coastal management
Genetic structure of the endemic Pecten jacobaeus of Aegean inferred from mitochondrial 16s DNA sequence analysis was performed. This genetic marker is a powerful tool for measuring genetic variation and gene flow among populations. Valuable scallop stocks were abundant in the past in Euboikos gulf...Read more
A detailed characterization of household Municipal Solid Waste
Mathioudakis D., (Corresponding) Papadopoulou K., Lytras G., Pavlopoulos C., Dimopoulos N., Niakas S., Melanitou H., Lekkas D., Lyberatos G.
Topic:
Solid waste management
Reliable data on Municipal Solid Waste composition are paramount for the development of environmentally sound, sustainable and economically viable integrated waste management systems. However, no standardized universally accepted waste characterization protocol has been developed, as there are...Read more
Effect of anthropogenic sources on total particles and Cloud Condensation Nuclei levels in the Eastern Mediterranean
(Corresponding) Bougiatioti A., Zarmpas P., Kalkavouras P., Mihalopoulos N.
Topic:
Urban environment and health
The absorption and scattering of radiation by atmospheric aerosol particles, especially those originating from anthropogenic activities, is a key component of anthropogenic climate change. Aerosol particles also act as cloud condensation nuclei (CCN) “indirectly” forcing climate through the...Read more
