Abstract of WO9514368
The method has an application in the industrial productions, which produce waste solutions, with various contaminants (organic matter, sulphate ions, ammonium ions, nitrite ions, nitrate ions, arsenic, cyanide, ions of heavy metals, radioactive elements, etc.). With this method a complex purification of waste solutions independently of their qualitative and quantitative composition is realized and it is minimum to SECOND CATEGORY for waters according to the BULGARIAN STATE STANDARD (State Newpaper, No. 96 from 1986 year). The essence of the method is: the waste solutions, containing contaminants independent of their concentrations, ascending and gravitationally pass through the system of biobasins with the form of "turned obelisk" through the supporting layer of broken carbonate rocks, iron and a source of organic carbon situated at the bottom of the basins, intensifying the activity of the applied mixed bacterial culture, adapted in a suitable way, obtained through the combination of activated sludge from the biobasins of a purifying municipal sewage plant and sludge from the digesters of such a plant concentrated additionally with a mixed culture of anaerobic microorganisms isolated from the sludge of polluted water accepting basin.
