| titleOfInvention | Removal of arsenic from water |
| abstract | There is disclosed awater purification process comprising, adding Fe(II) ions to water, b) subjecting the water to oxidizing conditions,c) leaving any formed complex in contact with the water for at least one hour, d) filtering away formed complexes, wherein complexes are in contact with the water which passes the filter, and e) retaining complexes in the filter for at least 24 hours, wherein the pH of the water is adjusted to be in the interval 5-7.5, wherein Fe(II) ions first are added in a ratio of Fe to As from 50 to 5000, and wherein Fe(II) ions subsequently are added in a ratio of Fe to As from 10 to 50. Advantages include a low consumption of Fe(II) ions, a possibility to reach very low concentrations of arsenic, no harmful or toxic additives are used, and arsenic is bound in stable complexes after removal from the water. |
