ABSTRACT Pollution from metals and metalloids of the environment of Greece seemed to attract many researchers and elemental pollutants in air, soil and water have been determined and studied systematically during the last decade. The most recent of these studies, concerning the last five years (2003...

Advanced oxidation processes (AOPs) are widely used for the removal of recalcitrant organic constituents from industrial and municipal wastewater. The aim of this study was to review the use of titanium dioxide/UV light process, hydrogen peroxide/UV light process and Fenton’s reactions in wastewater...

Enhancement of the permeate flux due to reduction of cake layer resistance by air-liquid twophase flow in a cross flow spiral wound microfiltration membrane has been investigated. Experiments were carried out with two different suspension systems, namely baker’s yeast suspension with a dry mass...

The goal of the current review is to present and analyze the known information proposed and discussed the last few years about UFP and their possible health effects. It includes references from 1992 to 2008. It also includes references from some fundamental studies in the 1970's and 1980's. The...

The traditional approach to urban water management is primarily based on a supply-oriented approach, where water follows a one-way path from supply to a single use, treatment and then discharged to the environment. The wide acknowledgement of the need to shift towards more sustainable practices has...

The present work concerns the investigation of the chemical kinetics of H2S selective oxidation into elemental sulfur, by gas absorption and chemical reaction in Fe3+·(ΝΤΑ) aqueous solutions. By using initial reactivity data, priority is given to the study of intrinsic kinetics i.e. to avoid...

A simple model is presented for the dynamic calculation of the sludge blanket height and concentrations of suspended solids (diluted, sludge blanket and return sludge) in circular secondary settling tanks. The model combines a mass balance equation with three empirical equations, which account for...

The concentrations of ozone, NO2 and SO2 measured by a Differential Optical Absorption Spectroscopy (DOAS) system in the city of Kozani in Northwestern Greece are presented and compared against data from a conventional ground station. This was made in order to assess DOAS performance in a...

As part of an effort to understand the water quality dynamics in the Kouris Dam and the impact of possible management strategies, the present study assessed the transport process of atrazine in this reservoir and the effects of bottom and surface withdrawal schemes. The 2- D laterally averaged CE...

Disposing of plastic wastes to landfill is becoming undesirable due to legislation pressures, rising costs and the poor biodegradability of commonly used polymers. In addition, incineration meets with strong societal opposition. Therefore, recycling either mechanical or chemical, seems to be the...
