The adsorption of the herbicide atrazine in packed beds filled with solids modelling soil components, (silica and humic acid), was studied at conditions simulating the adsorption of atrazine in cultivated soils. The choice of only two constituents of soil in the experimental study was based on the...

Landfilling is one of the most common ways of municipal solid waste (MSW) disposal in developing countries. Air pollutants emitted from landfills contributes to the emission in the atmosphere of greenhouse gases and cause serious problems to the human health. Methane emission from landfill is...

Anionic poly(sodium acrylate), PANa, hydrogels bearing negatively charged –COO- groups were used as sorbents for the removal of colored organic or inorganic model pollutants, namely Crystal Violet and Cu2+, from water. It was found that PANa hydrogels adsorb stronger Cu2+ions than Crystal Violet, as...

An Upflow Anaerobic Sludge Bed (UASB) reactor was used to evaluate mesophilic anaerobic treatment of a pre-acidified fruit wastewater. The system was operated at increasing volumetric loading rates by sequentially increasing wastewater flowrate. The operational temperature was maintained initially...

The stringent new regulations to lower sulfur content in fossil fuels require new economic and efficient methods for desulfurization of recalcitrant organic sulfur. Hydrodesulfurization of such compounds is very costly and requires high operating temperature and pressure. Adsorption is a non...

The present study concerns the impact of a change in the rainfall regime on surface and groundwater resources in an experimental watershed. The research is conducted in a gauged mountainous watershed (15.18 km2) that is located on the eastern side of Penteli Mountain, in the prefecture of Attica...
