Latest Patents

One of his notable patents is an "Apparatus for the treatment of wastewater." This invention features an enclosed unit that provides a facultative zone where a mixture low in dissolved carbon, comprising raw sewage and partially processed sewage, undergoes denitrification. This process is facilitated by facultative organisms in a low oxygen environment. The effluent from this facultative zone is then directed into a columnar oxidation unit, where controlled air or oxygen flow oxidizes nitrogen compounds into nitrates. The design also includes a columnar denitrification zone that effectively removes nitrogen gas from the nitrates, resulting in an effluent with low nitrate content.

Another patent focuses on "Gas removal from deep-bed filters." This invention addresses the issue of gas bubbles, particularly nitrogen gas, generated during the denitrification process. The method involves venting gas bubbles from below the surface of the filter bed and enhancing gas removal by introducing pressurized air or water to dislodge the bubbles, allowing them to rise and be vented to the atmosphere.
