Research Abstracts

This study focused on a comparative evaluation of wastewater from a chromium-based tannery in Izmir (Turkey). Two sampling campaigns included raw wastewater (R), the effluents of coagulation/flocculation process (CF), biological treatment (B) and dried sludge (DS). Samples were analyzed for their me

The MEDAWARE project (which is funded by the Europe Aid program of EU) aims at addressing the significant issue of sustainable urban wastewater treatment and reuse in the agricultural production through the promotion of effective technologies and safe practices. The general objective of this project

A preliminary chemical treatment of pentachlorophenol, isoproturon, diuron, alachlor and atrazine pesticide aqueous solutions (all them belonging to the list of priority pollutants of the European Union) based on a combination of ozone and photo-Fenton reagents has been used to generate intermediate

In this study, methylene blue (MB) was chosen as a model dye to test a novel photocatalytic reactor using titanium dioxide (TiO2) nanofilm. TiO2 photocatalysis is a light-activated process that has been successfully applied to remove organic and inorganic pollutants from water and wastewater. The re

Due to stringent discharge limits, various pollutants (xenobiotics, biorecalcitrants, persistent) need to be handled carefully. A class of chemicals synthesized for tanning or retanning purposes in the leather tanning industry is collectively termed synthetic tannins (syntans, ST), resins (acrylic),

The present study examines the concentrations of Cd, Cu, Mn, Ni, Pb and Zn in 2004 in the Saronikos Gulf, an embayment affected by anthropogenic inputs from the nearby metropolitan area of Athens. We investigated in particular the impact of the operation for a decade of the primary Wastewater Treatm

Synthetic chelating agents are used to increase the phytoextraction of metals from contaminated soils, however the increased bioavailability of the metals may increases the potential risk of groundwater contamination. In this study, 4 mmol EDTA kg–1 was applied using four application methods to a Cd

The aim of this study is to present the seasonal variation of nutrients in the water column and the bottom sediments of Vistonis Lagoon, a hypereutrophic Mediterranean coastal lagoon located in Northern Greece, and to estimate the impact of bottom sediments on the water quality of this lagoon. Nutri

Humic substances mainly humic acids constitute the major fraction of natural organic matter in water supplies. Humics express diverse actions primarily related to the formation of potentially harmful disinfection by products (DBPs). Therefore, the removal of DBP precursors through numerous treatment

One of the most important tasks at any water treatment plant is safeguarding the quality of drinking water. Worldwide, the drinking-water sector is increasingly aware of the limitations of end-product testing for ensuring safety. One limitation is the steady increase in the number of potentially occ
