| Number | Title | Issue Date |
| 6852305 | Process for the production of hydrogen sulphide from elemental sulphur and use thereof in heavy metal recovery A process is provided for the production of hydrogen sulphide from the bacterial reduction of a mixture of a liquid and elemental sulfur with an electron donor, such as hydrogen gas, carbon monoxide or organic compounds. The bacteria may be Desulforomonas sp.... | 02/08/2005 |
| 6841072 | Method and device for the anaerobic purification of a slurry which contains organic constituents Method and apparatus for the anaerobic purification of slurry which contains organic constituents. Slurry which is to be treated is fed periodically or continuously to a mixture-filled, substantially closed reactor (2), while the slurry is forcibly mixed with... | 01/11/2005 |
| 6656249 | Method for desulphurization of gases A method of removing hydrogen sulphide from a gas stream wherein the hydrogen sulphide is scrubbed from the gas phase by an aqueous solution, the hydrogen sulphide in the aqueous solution is biologically oxidized in a bioreactor to produce elemental sulph... | 12/02/2003 |
| 6656722 | Process for immobilizing arsenic waste The invention provides a process for removing and immobilizing arsenic from an arsenic-containing waste. It comprises oxidizing the arsenic to pentavalent arsenic in an aqueous medium, contacting the pentavalent arsenic with trivalent iron to form an inso... | 12/02/2003 |
| 6630071 | Process for the treatment of waste water containing heavy metals A process for the treatment of waste water containing heavy metals in which sulphur components and/or metals are biologically reduced to precipitate the metals as water-insoluble metal species, which are separated from the waste water. The biological redu... | 10/07/2003 |
| 6485646 | Process for the treatment of waste water containing ammonia A process is described for the biological treatment of waste water containing ammonia, wherein the waste water is treated with sludge containing nitrifying bacteria in an aerated reactor, applying a sludge retention time in the reactor which favours nitri... | 11/26/2002 |
| 6221652 | Process for biological removal of sulphide A process for the removal of sulphides, including hydrogen sulphide, carbonyl sulphide and carbon disulphide, from a gas stream by scrubbing the gas with an aqueous washing liquid and treating the washing liquid with sulphide-oxidizing bacteria in the pre... | 04/24/2001 |
| 6156205 | Process for the purification of gases containing hydrogen sulphide A process for scrubbing a gas containing hydrogen sulphide and/or carbonyl sulphide, in which the spent scrubbing liquid is treated with autotrophic sulphide-oxidizing bacteria capable of oxidizing at high pH, and elemental sulphur is obtained, the elemen... | 12/05/2000 |
| 6045695 | Biological treatment of spent caustics A process for the biological treatment of a spent caustic solution containing sulphides is disclosed, wherein the solution is introduced into an aerobic reactor containing sulphide-oxidising bacteria, and the sulphides are partly converted to elemental su... | 04/04/2000 |
| 6019901 | Process for removing polyamine chelating agents form aqueous solutions The invention provides a process for removing polyamine chelating agents from aqueous solutions comprising oxidising the chelating agents with oxygen in the presence of an equivalent amount of a transition metal such as iron, followed by biologically redu... | 02/01/2000 |
| 5976868 | Process for the treatment of gases An installation and a method are described for the treatment of a gas containing hydrogen sulphide, the gas (1) being washed in a first gas scrubber (5) with an alkaline wash liquid and the spent wash liquid (4) being treated in an aerobic reactor (6) wit... | 11/02/1999 |
