Characterization study of manganese and iron oxides-coated sand filters

الملخص EN

A brief description of sand filter design used in a conventional water purification plant, illustrate the formation of manganese iron-coated layer on sand filter’s grains.

Manganese iron-coated formed from the sorption of manganese oxides during long-term filtration via the process of sand filtration, prior by aeration in a water treatment plant.

The contaminated sand filter was studied radioactively and chemically by several analytical techniques, first a scanning electron microscopy analyses were used to investigate the surface properties of the coated layer.

An energy dispersive X-ray (EDAX) and XRF techniques analysis were used to characterize metal adsorption sites on a oxides-coated sand filters surface and Chemical composition.

Mineralogy of the oxide coating was characterized by X-ray diffraction.

Finally radioactive study was accomplished by gamma spectroscopy system with a high resolution germanium detector.
