Title: Innovations and Contributions of Inventor Norman J Wagner
Introduction
Norman J Wagner is a notable inventor based in Pittsburgh, PA, with a significant contribution to the field of environmental engineering. He holds a total of six patents, showcasing his innovative approaches to solving complex problems related to water purification and gas stream contamination.
Latest Patents
One of his latest patents involves a process for the removal and destruction of perchlorate and nitrate from groundwater and drinking water sources. This innovative process concentrates the perchlorate and nitrate anions present in feed water into a much smaller effluent stream. The configuration utilizes a continuous contacter apparatus known as ISEP, where perchlorate is adsorbed onto an ion-exchange resin, resulting in treated water free of perchlorate. The ISEP unit also features a regeneration zone that effectively removes the adsorbed perchlorate using low volumes of concentrated brine solution. The waste generated is a concentrated brine solution containing perchlorate and other anions, which is treated through a combination of bioreactors or catalytic reactors, sulfate removal, and filtration systems, allowing for the recycling of the resulting stream back into the process. This entire method results in a minimal waste stream requiring disposal.
Another significant patent addresses the removal of acidic contaminants from gas streams using caustic impregnated activated carbon. This process purifies gas streams contaminated with acid and acid precursor gases by contacting them with activated carbon that has been impregnated with sodium hydroxide.
