    Abstract: An electric plasma arc apparatus and method produces nitrogen compounds, solely using ambient air extracted in proximity to the apparatus. The nitrogen compounds are brought into contact with a water processing system, forming nitrate on-site. Hydrogen sulfide present in the water processing system is removed, and the production of hydrogen sulfide by sulfate-reducing bacteria (SRB) is eliminated by introducing nitrate into the system, whereby denitrifying microorganisms, using the nitrate, outcompete the sulfate-reducing bacteria for the available carbon nutrients, thus preventing the SRB from producing hydrogen sulfide.

  • Patent number: 7866921
    Abstract: An apparatus and method to internally provide apertures inside PVC, HDPE, or plastic pipe-riser (blank casing) in existing methane gas recovery wells (extraction wells) that have been installed at Municipal Solid Waste Facilities are described. Apertures in methane well risers allow methane gas, LFG derived from the decomposition of waste, to enter the existing riser and extraction system. This process saves time and cost associated with drilling additional wells to retrieve methane gas from subsequent layers of the waste body. The process assists in maintaining regulatory compliance by capturing LFG and preventing it from being emitted into the atmosphere.
