METHOD FOR ACTIVATION AND REGENERATION OF A FILTER MATERIAL AND THE FILTER MATERIAL THUS OBTAINED |
| 摘要 |
The present invention relates to a filter material for water filters based on inorganic surfaces, whether they are natural or synthetic that it is regenerated after its first use and a method for activating and regenerating the filter material by the use of inert salt solutions and the energy provided by microwaves. |

1. A method for activation and regeneration of a filter material, comprising:
providing an inorganic filter material previously used; passing a first flow of a solution of inert salts over a surface of the material with a concentration between 0.5 and 1.5 M, radiating the material with microwaves with a potency between 600 to 1000 Watt; centrifuging the obtained material; recovering solid precipitate to be subjected to a new filtering cycle; subjecting the recovered filter material to a second flow of a solution of inert salts at a concentration between 1.5 and 3.5, radiating the material with microwaves; centrifuging again the material; and recovering the solid precipitate for using in a new filtering cycle. |
