TREATMENT AND REGENERATION SYSTEM AND METHOD FOR EXTRACTING ORGANIC SOLUTES FROM-WATER
Provided is a system and method for extracting organic solutes from water with a filter media. The system and method allow for regenerating the filter media following treatment of a water supply containing one or more organic solutes to allow the media to be reused for subsequent water treatment operations. The system and method also allows for regeneration of the displacement fluid for reuse in the regeneration of the media with recovery of at least one or more organic solutes from the displacement fluid. Additionally, the system and method allows for substantially continuous treatment of a water supply and regeneration of a filter media.
METHOD FOR PURIFYING FRESH, COMBINED AND SALINE WASTEWATER FROM RADIOACTIVE HEAVY METALS
The invention relates to environment management, particularly to methods for purifying a wastewater in order to eliminate a toxic impact of heavy and radioactive metals. A method for purifying fresh, combined and saline wastewater from radioactive and heavy metals using an electrolysis and a special active substance (sorbent), wherein the wastewater is fed to an electrolyzer with a chamber that is separated by a special membrane that is permeable for ions of metals separately of water, then changes of the pH occur in order to form complex compounds, which comprise ions of radioactive and heavy metals. Afterwards, the adsorption of the obtained 0 compounds by the special active substance (sorbent) and filtering-off on a precoat filter that retains ions of heavy and radioactive metals are performed. The obtained filtrate is cemented without drying and evaporation in order to perform final deposition of the radioactive 0 compounds.
