|20140345649||SYSTEM AND METHOD FOR REMEDIATING HIGHLY CONTAMINATED FINE SOIL USING MULTIPLE MICRO HYDROCYCLONE - The present invention relates to a system for remediating highly contaminated fine soil using multiple micro hydrocyclones that includes: a mill adapted to mix contaminated soil with water and to individualize the soil; a screen adapted to separate the soil introduced from the mill into soil having given particle sizes; a separator adapted to finely separate the soil having particle sizes of less than a given value by particle size from the soil having the given particle sizes separated through the screen; a remediating unit adapted to wash the finely separated soil introduced from the separator by particle size by means of process water for washing; and a filtering unit adapted to separately discharge the soil washed and introduced through the remediating unit and the process water for washing contained in the soil.||11-27-2014|
|20140321916||SYSTEM AND METHOD FOR REMEDIATING CONTAMINATED SOIL BY SEPARATION OF HIGHLY CONTAMINATED COARSE SOIL - The present invention relates to a system and method for remediating contaminated soil through separation and process of highly contaminated coarse soil, the system including: a screen adapted to separate the contaminated soil introduced into soil having given particle sizes; multiple hydrocyclones adapted to re-separate the soil having particle sizes of more than the given values by particle size from the soil having the given particle sizes separated through the screen; a remediating unit adapted to wash the soil separated through the multiple hydrocyclones by particle size; and a filtering unit adapted to separate water from the soil washed through the remediating unit.||10-30-2014|
|20130295625||Apparatus and Method for Treating Organic Waste - The present invention relates to an apparatus for treating organic waste including: a first circulation line having a first circulation pump connected thereon so as to supply a portion of the organic waste being acid fermented in an acid fermenter to a methane fermenter; a second circulation line having a second circulation pump connected thereon so as to supply a portion of anaerobic digestive fluid methane fermented in the methane fermenter to the acid fermenter; and vortex generating means having a plurality of first, second and third nozzles disposed in the methane fermenter so as to allow the anaerobic digestive fluid in the methane fermenter to be agitated by vortices generated thereof.||11-07-2013|
|20120107049||TUNNEL REINFORCEMENT STRUCTURE AND TUNNEL CONSTRUCTION METHOD CAPABLE OF CONTROLLING GROUND DISPLACEMENT USING PRESSURIZATION - The present invention relates to a tunnel reinforcement structure capable of controlling ground displacement using pressurization, including: reinforcements adapted to be forcedly inserted into the bored holes formed along the outer surface of the section to be excavated of the tunnel; auxiliary reinforcements disposed between the reinforcements from a point between 4 m and 8 m inwardly from the ends of the reinforcements; steel ribs disposed on the inner four faces of the excavation face of the tunnel; pressurizing bags each provided between the steel ribs and the excavated inner surface of the tunnel; a concrete part adapted to be cast between the steel ribs; and lining concrete adapted to be cast to the steel ribs and the inner surface of the concrete part.||05-03-2012|
