Current status of the metal pollution of the environment of Greece - a review
General
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...
Use of selected advanced oxidation processes (AOPs) for wastewater treatment - a mini review
General
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...
Flux enhancement by air dispersion in cross-flow microfiltration of a colloidal system through spiral wound module
General
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...
Ultrafine particles (UFP) and health effects. Dangerous. Like no other PM? Review and analysis
General
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...
Integrated urban water modelling using Aquacycle model
General
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...
Treatment of the effluent from a kraft bleach plant with white rot fungi Pleurotus sajor caju and pleurotus ostreatus
General
The final effluents from pulp and paper industry, even after biological treatment, often contain a plethora of unwanted by-products, which confer them colour and toxic characteristics. The aim of this work was to promote degradation of organic matter and remove colour by contacting fungi Pleurotus...
Simple estimation of granule size distribution and sludge bed porosity in a UASB reactor
General
Granular sludge is the key factor for an efficient operation of an upflow anaerobic sludge blanket (UASB) reactor. In order to monitor the granularity of anaerobic sludge, the determination of the granule size distribution is of vital importance. Another critical parameter for the UASB reactor...
An experimental study of the indoor air quality in areas of different use
General
The purpose of the present work was to study experimentally the indoor air quality status regarding PM10, PM2.5, TVOCs, CO2, NOx, SO2 and O3 in selected differently used areas. A flat on the third floor of a multi-storey building, located at a suburban area north-east of the centre of Athens and...
Modelling and simulation of a catchment in order to evaluate water resources
General
It is difficult for decision-makers to evaluate the impact of their territorial policies. Aspects to be considered in this evaluation include those relating to humans, environment protection and industry development. Two reasons explain the difficulty: decision-makers cannot specialise in all...
Investigation of the effect of ultrasonic waves on the enhancement of efficiency of direct photolysis and photooxidation processes on the removal of a model contaminant from textile industry
General
The effect of ultrasonic waves (US) was studied on the degradation of Malachite Green (MG) as a model contaminant from textile industry by direct photolysis with ultraviolet (UV) radiation and UV/H2O2 processes. The US (35 kHz) and UV (253.7 nm) radiations were carried out with an ultrasonic bath...
