Title: Thomas J Vollstedt: Innovator in Wastewater Treatment
Introduction
Thomas J Vollstedt is a notable inventor based in Schofield, Wisconsin. He has made significant contributions to the field of wastewater treatment, holding a total of 5 patents. His innovative approaches focus on improving the purification processes for wastewater, making them more efficient and effective.
Latest Patents
Vollstedt's latest patents include a two-stage anaerobic/aerobic treatment process. This process involves biophysical anaerobic treatment to remove the majority of the chemical oxygen demand (COD), followed by biophysical aerobic treatment for further purification. A powdered adsorbent, preferably activated carbon, is utilized in both treatment steps. Excess biophysical solids from the aerobic step are transferred to the anaerobic step for digestion, ensuring a continuous and efficient treatment process.
Another significant patent is the two-stage batch wastewater treatment. This process purifies wastewater containing organic and adsorbable pollutants by introducing a predetermined quantity of wastewater into an aeration and settling zone. The wastewater is aerated in the presence of a powered adsorbent and biologically active solids. After aeration, the treated wastewater is retained for a sufficient time to allow suspended solids to settle by gravity. The clarified, substantially solids-free water is then withdrawn from the contact zone, showcasing Vollstedt's innovative approach to wastewater management.
Career Highlights
Throughout his career, Thomas J Vollstedt has worked with several prominent companies, including Zimpro/Passavant Inc. and Sterling Drug Inc. His experience in these organizations has contributed to his expertise in wastewater treatment technologies.
