Title: Innovations in Wastewater Treatment by Thierry Lebrun
Introduction
Thierry Lebrun is a notable inventor based in Villecresnes, France. He has made significant contributions to the field of wastewater treatment, holding 2 patents that focus on improving purification methods and reducing sludge production.
Latest Patents
One of his latest patents is a method for purifying wastewater with an added oxidizing agent. This invention involves a process where wastewater loaded with organic matter is contacted with a biological culture containing a purifying biomass. The method includes a filtration step through organic or inorganic membranes. A key feature of this invention is that part of the biological culture undergoes oxidative stress, which helps to preserve the biological activity of the purifying biomass while enhancing the density of the microbial floc.
Another significant patent by Thierry Lebrun is a method for reducing the production of sludge at wastewater treatment stations using fixed biological cultures. This method first purifies wastewater with these cultures, from which excess sludge is intermittently extracted during washing and unclogging phases. The water from the washing phase is then treated with biological activated sludge, and the process includes a stage of reduced sludge production, utilizing thermophilic enzymatic action or partial oxidation by ozone.
