Title: Innovations by Joachim Lemke in Sewage Sludge Treatment
Introduction
Joachim Lemke is a notable inventor based in Wuppertal, Germany. He has made significant contributions to the field of sewage treatment through his innovative methods. His work focuses on improving the dewatering process of sewage sludge, which is crucial for environmental management.
Latest Patents
Lemke holds a patent for a conditioning method for dehydrating clarification sludge. This process involves a combination of acidic oxidative preconditioning and inorganic post-conditioning. The preconditioning step includes acidifying the sewage sludge and performing catalytic partial oxidation using a substoichiometric amount of hydrogen peroxide and iron ions at a pH of less than or equal to 5. Following this, the inorganic post-conditioning is carried out by mixing the acidified and partially oxidized sludge with alkaline earth materials, specifically ensuring that sufficient calcium hydroxide (Ca(OH)₂) is added to maintain a pH between 9 and 11. This innovative approach allows for effective mechanical dewatering of the conditioned sewage sludge.
