Clean up of acidic leachates using fly ash barriers: Laboratory column studies

by

Komnitsas K., Bartzas G. and Paspaliaris I.

General

Laboratory column tests were conducted to study the efficiency of lignite fly ash barriers in removing heavy metal ions, such as Fe, Zn, Mn, Ni, Cd, Co, Al and Cu, present in high concentrations in acidic leachates produced in mining and waste disposal sites. The experimental configuration comprised...

Polluted Water Effluent in the Sea

by

Demetriou J. D.

General

In this experimental study some measurements and their analysis are presented concerning the polluted water effluent disposal in the sea water. The wastes are disposed through the round openings of a submerged in the sea diffuser, in the form of turbulent jets which are mixing (diffusing) with the...

Sorption and de-sorption of 2,4 -D and Atrazine from water environment by waste tyre rubber granules and its management

by

Alam J.B., Dickshit A.K. and Bandyopadhyay M.

General

Waste tyre rubber granules were used as sorption medium in water treatment technology to remove up to 1 mg l-1 of 2,4-D and atrazine. The removal was found to be 83.2% and 87% corresponding to initial concentration of 0.5 and 1 mg l-1 of 2,4-D whereas it was 84.2% and 87.6% for atrazine. On the...

Lead and copper contamination in small arms firing ranges

by

Dermatas D., Menouno N., Dutko P., Dadachov M., Arienti P. and Tsaneva V.

General

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...

Improvement of H2O2 Stabilization in Rainwater Samples

by

Ceron R.M., Muriel M. and Ceron J.G.

General

Peroxides collected in rainwater readily decompose in the natural matrix, consequently it is hard to estimate their values present during precipitation events. For this reason, only few data concerning the concentration of aqueous H2O2 in dew, cloud and rainwater are available. Therefore, it is...
