The objective of this pilot-study is to evaluate the Granular Activated Carbon (GAC) performance for the removal of specific disinfection by-products (DBPs), trihalomethanes (THMs) and haloacetic acids (HAAs), from Athens drinking water. For this purpose, a GAC pilot filter-adsorber was operated in...

At present, chemical processes are widely used to remove phosphorus and organic matter from water or wastewater either as the only advanced treatment method or as a pre-treatment stage to biological treatment, and aluminium salts have been traditionally used as coagulants. In the present study...

The mechanism of Methylene Blue adsorption on biosolid (waste sludge) has been studied through batch experiments. The effects of various experimental parameters, such as pH (3- 11), biosolid dosage (1-10 g l-1), contact time (5-1440 min) and initial dye concentration were investigated. The results...

Combustion of poor quality coals is used today worldwide for energy production. The removal of polluting compounds, i.e. S, N, Hg and Cl from them prior to combustion is important not only for improving the coal quality, but also for meeting the strict environmental standards. Thus, a preventive...

Pollution of the environment with uranium and associated health effects to human have recently become of major concern, particularly due to the use of depleted uranium in armourbreaking bullets. Indeed, uranium in environmentally significant concentrations is found near to uranium mining and...
