20080223789 | MATERIAL AND A METHOD FOR REMOVING OXO-ANIONS AND METAL CATIONS FROM A LIQUID - A material for removing oxo-anions and metal cations from a liquid. This material is characterized in that it comprises hyperthermophilic ferritin. The present invention also relates to a method for removing at least one of oxo-anions and metal cations from a liquid. This method is characterized in that a material comprising hyperthermophilic ferritin is used as filter material. It is especially preferred that said liquid is comprised of water. The invention also relates to the use of hyperthermophilic ferritin for removing metal cations and oxo-anions from a liquid. | 09-18-2008 |
20130256223 | BIOLOGICAL WASTEWATER TREATMENT AND REUSE UTILIZING SULFUR COMPOUNDS AS ELECTRON CARRIER TO MINIMIZE SLUDGE PRODUCTION - Biological wastewater treatment of wastewater is performed by oxidizing organic carbon with sulfur or a sulfur compound as an electron carrier, and reducing the sulfur or sulfur compound to sulfide. The sulfide is oxidized with nitrate or oxygen. If necessary, ammonia is oxidized to nitrate and then reduced to nitrogen gas. The process is effective for saline waste water facilities, as well as non-saline waste water facilities. | 10-03-2013 |

20090282882 | PROCESS FOR THE CONVERSION OF LIQUID WASTE BIOMASS INTO A FERTILIZER PRODUCT - A process for the treatment of liquid waste biomass, especially liquid manure compositions, wherein the biomass is converted to a fertilizer product. The process at least includes a nitrification step including a first biological conversion stage wherein ammonium is converted to nitrite using nitritifying bacteria in an aerated reactor, and a subsequent chemical oxidation stage wherein nitrite is converted to nitrate by heating the liquid waste biomass in an aerated reactor under acidic conditions. The process is particularly suitable for treating liquid manure, because of the high ammonium nitrogen contents thereof, which render the process essentially self-regulatory. In addition a process for the treatment of liquid waste biomass wherein organic matters are converted to energy sources, referred to as biogas and green cokes, and wherein nitrogen is fixed in a fertilizer product in the form of ammonium nitrate, is provided, the process including the present nitrification process. | 11-19-2009 |
