Title: Innovations of Joseph Dussaud in Environmental Technology
Introduction
Joseph Dussaud, an inventive mind located in Vienne, France, has made significant contributions to environmental technology through his ten patents. His work focuses on developing advanced filtering mediums that utilize activated carbon and other materials for effective pollution removal.
Latest Patents
Dussaud's latest inventions reflect his commitment to environmental sustainability. One notable patent details a filtering medium designed specifically for pollution removal from lagoons. This innovative filtering medium is comprised of three superposed layers. The inner layer consists of 80 to 95% by dry weight of activated carbon, with the remaining material made up of organic and/or inorganic chemical fibers. The first outer layer contains 45 to 95% by dry weight of these chemical fibers, supplemented by activated carbon or a lighter material. The second outer layer includes 5 to 25% by dry weight of activated carbon and additional chemical fibers. The specified weights for these layers ensure maximum effectiveness in filtration, ranging between 40 to 200 g/m² for the inner layer and 10 to 100 g/m² for the outer layers.
Another patent highlights a method for creating a filtering medium that employs both a photocatalytic agent and activated carbon. This innovation features a permeable support that is layered strategically with activated carbon and a photocatalytic agent. This dual-layer approach not only enhances filtration efficiency but also adds a new dimension to environmental remediation technologies.
