Latest Patents
One of his latest patents is titled "Method and system for removal of selenium from FGD scrubber purge water." This invention outlines a method for effectively removing oxy-anions of selenium from flue gas desulfurization (FGD) scrubber purge water. The process involves contacting the purge water with free hydroxyl radicals to oxidize reduced forms of sulfur to sulfate and to destroy sulfur-nitrogen compounds. Following this, the purge water undergoes chemical reduction and co-precipitation with ferrous ions, allowing for the removal of selenium in under 30 minutes. The resulting ferrous-selenium solids are then separated and stabilized to elemental selenium in a separate reaction vessel.
Another significant patent is the "Bio-slurry reaction system and process for hazardous waste treatment." This method enhances slurry-phase bioremediation treatment of organic sludge and contaminated soils. It involves dissolving contaminants into an aqueous phase for microbial degradation. A high solids slurry is formed, which is passed through a series of bioreactors that maintain low hydraulic shear to promote the growth of microorganisms. The output is continuously or semi-continuously directed to a liquid-solids separator, allowing for the recycling of the mixed liquor bioslurry.
