SORAS
| Title | Description | File |
| SORAS - a simple arsenic removal process. |
SORAS (Solar Oxidation and Removal of Arsenic in
Drinking Water) is a simple water treatment method that uses sunlight and
plastic bottles to reduce arsenic levels in drinking water. The process is based
on photochemical oxidation of As(III) followed by precipitation or filtration of
As(V) adsorbed on Fe(III)oxides. Groundwater polluted by arsenic often contains
also iron as Fe(II) or Fe(III) used for the removal of arsenic. In such
situations, SORAS reduces arsenic contents to approx. 50 – 80 %. The water
treatment method is used at household level to treat small quantities of
drinking water at virtually no cost.
