Latest Patents
One of his latest patents is titled "Microbial mediated chemical sequestering of phosphate in a closed-loop recirculating aquaculture system." This invention presents a system and method for the removal of phosphates from a closed-loop estuarine or marine recirculating aquaculture system (RAS). It involves denitrification in the presence of a media substrate, which facilitates anaerobic nitrate, nitrite, and ammonia removal while sequestering excess phosphate in the RAS. The phosphate is precipitated in or on the denitrifying biofilm formed on the media substrate as phosphate salts. The phosphate salt-containing media substrate can be removed from the RAS, allowing for the removal and recycling of both the substrate and the phosphates.
Another significant patent is "Dissimilatory sulfate reduction as a process to promote denitrification in marine recirculating aquaculture systems." This invention introduces a novel approach for nitrate removal from a marine recirculating system. It utilizes high concentrations of sulfate found in seawater in combination with sludge collected from fish growing tanks to promote dissimilatory sulfate reduction to hydrogen sulfide. The sulfide serves as an electron source to enhance autotrophic denitrification in an up-flow fixed bed bioreactor, followed by nitrification in a nitrification unit. This method effectively controls nitrate accumulation in the recirculating water, thereby reducing the need for water exchange in the marine recirculating system.
