Various investigations have been carried out to evaluate the infrastructure’s augmented vulnerability owing to concrete carbonation persuaded by the changes in the environment during recent years. Due to global warming and its effect, carbon dioxide emission levels in the atmosphere get increased...

In the presence of nitrogen oxides, nitrate-reducing bacteria (NRB) may use nitrate as an electron acceptor, reduce nitrate to nitrite, and finally convert nitrite to nitrogen or ammonium (NO and N2O). Studies have shown that BCX (Bio-Competitive Exclusion) is a viable , ecologically benign, and low...

Tannery industries provoke the conspicuous quantity of deleterious effluent which has to be treated prior to discharge into the environment. Pre-treatment of tannery wastewater with aluminium sulphate is well known over decades, but due to the corrosive nature of sulphate this pre-treated water...

Industrial facilities emit pollutant air that contains volatile organic compounds (VOCs) and reduced sulphur compounds (RSCs) which are nuisance, corrosive to materials and dangerous to health. In recent years, biofiltration has replaced numerous conventional processes (i.e. adsorption) due to its...

More than 73% of the electrical power requirements of Greece are generated in lignite-fired power plants. Greece is the thirteenth largest coal and the fifth largest lignite producer in the world. The lack of domestic high-rank coals makes necessary to use low quality lignite for power generation in...

Coals contain elements which, although usually found in concentrations lower than 1% (trace elements), can give rise to environmental or technological problems. After gasification most of these elements may occur in gas phase in different proportions. In order to avoid the problems that the presence...

The present paper deals with water quality modification during its stagnation in copper distribution pipes caused by electrochemical corrosion processes. Copper is chosen as plumbing material because of its wide use in drinking water distribution systems all around the world, and because of its...

Firing range activities have been proven to adversely impact the environment. The main concern in small arms firing ranges (SAFRs) is the fate and transport of heavy metals from bullets and bullet fragments accumulating in soil with lead (Pb) being the primary contaminant. Frequently however...
