Title: Richard Stickel: Innovator in Biological Purification Technologies
Introduction
Richard Stickel is a notable inventor based in Bad Dürkheim, Germany. He has made significant contributions to the field of biological purification of sewage and wastewater treatment. With a total of 3 patents, his work focuses on innovative processes that enhance environmental sustainability.
Latest Patents
One of Stickel's latest patents is a process and apparatus for the biological purification of sewage. This invention addresses the treatment of effluent contaminated with nitrogen in various forms. The process involves oxidizing nitrogen under aerobic conditions and reducing it under anaerobic conditions. The sewage is treated in an aeration basin where it is mixed with activated sludge and subjected to oxygen-containing gas bubbles. This method not only oxidizes carbon and nitrogen compounds but also facilitates the upward transport of treated sewage, which is then directed to a denitrification basin for further processing.
Another significant patent involves the treatment of wastewater produced in the manufacture of expandable polystyrene. This process includes passing a stream of fine gas bubbles through the wastewater and removing the resulting foam that contains a high concentration of impurities. This innovative approach allows for the potential further treatment of the aqueous phase.
