Results of a monitoring project for the water quality of three important rivers of western Greece (Acheloos, Louros and Acherontas) are presented in this paper. The results include the concentrations as well as the temporal and spatial distributions of nitrates, nitrites, phosphates, ammonia and...

The formation of chlorination by-products (CBPs) was investigated by bench-scale chlorination experiments with surface waters from different sources in Lesvos island, Greece. The main factors studied were organic matter content of water (expressed as UV-272 absorbance), time and chlorine dose. The...

Pollutants posing health risks to human health and to the aquatic environment often occur in drinking and surface waters, as a result of disinfection practices, agricultural and industrial activities, wastewater discharges. Toxic pollutants belong to different chemical categories, including...

A pilot-plant study was carried out with the water supply to Athens water works filtered through a granular activated carbon (GAC) filter- adsorber. The objective of this study was to evaluate the performance of GAC for the removal from drinking water of the two main groups of disinfection by...

The results of a research study about the groundwater quality in western Thessaly, that took place during the period 2001-2002, are presented in this paper. The study included two samplings during May and August of 2002. In May the water table is at high level while at the end of the summer the...

The sustainable management of water resources often requires the identification of wastewater as a valued source of water. Although the benefits of wastewater reuse and reclamation have increased significantly in Europe because of the advances in effectiveness of wastewater treatment and...

The establishment of the Wastewater Treatment Plant of Athens is considered as the main factor contributing to the improvement of water quality and recovery of the marine ecosystem in Saronicos gulf as it removes significant percentage of pollutants entering the gulf, including heavy metals. The...

The paper discusses a methodology for integrated municipal wastewater management. In compliance to the EU Directive 91/271, there is a legal binding to ensure that all agglomerations with populations over 2000 are provided with wastewater collecting system and adequate treatment. The conditions for...

This study was conducted to assess the removal efficiency of Di-n-butyl phthalate (DnBP) from aqueous medium using the photo-Fenton process. The Fenton's reagent that consists of a mixture of hydrogen peroxide (H2O) and ferrous ions (Fe2+) was used to generate the hydroxyl radical (OH0) that attacks...

A procedure that should be implemented for the evaluation of materials suitability, in terms of their use as metal retention agents, is presented. It derives from a review of materials and waste treatment mechanisms, which has been studied and is also presented. Lignite fly ash, agricultural ashes...
