Influence of nitrogen dioxide and acetylene on marbles, ceramics and pigment
General
The air pollution has a great impact on the social and economic aspects all over the world. Thus, the interaction of materials with the atmosphere has received increased attention nowadays. In order to estimate the impacts of air pollution on the solid surfaces a suitable scientific basis is...
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...
Indoor and outdoor PM concenctration at a residential environment, in the Athens area
General
The aim of the present work was to study exposure to PM in the indoor and outdoor microenvironment of a typical residence in the center of Athens. Simultaneous indoor and outdoor measurements of PM10 and PM2.5 were conducted, by the use of gravimetric and continuous samples, during October and...
The degradation of phenol in water solution by TiO2 photocatalysis in a helical reactor
General
Heterogeneous photocatalysis is an advanced oxidation process (AOP) which has been widely studied by numerous researchers in the world and is used to degrade or remove a wide range of pollutants in water and air. The photocatalytic oxidation and mineralization of phenol in aqueous catalyst...
Wet oxidation characteristics of metal cyanide complexes below 423 K
General
In the present study, the wet oxidation of zinc and copper cyanide complexes (cyanide concentration of 1,000 mg dm-3) was conducted in a hydrothermal reactor, under oxygen atmosphere of which the pressure was set to 1 MPa. The pH of the reaction solution was kept in the range of 11 to 12 and the...
Emissions from Irish domestic fireplaces and their impact on indoor air quality when used as supplementary heating source
General
A field study on the impact of fireplace on the indoor air quality was carried out between 2004 and 2006, where two main contaminants, CO and particulate matters, were investigated in twenty seven randomly selected Irish houses. The results show that while the physical environment has been improved...
