Title: Innovations of John W. Wittmann in Wastewater Treatment
Introduction
John W. Wittmann is a notable inventor based in New Berlin, WI (US), recognized for his contributions to wastewater treatment technologies. With a total of 4 patents, Wittmann has developed innovative processes that enhance the efficiency and effectiveness of wastewater management.
Latest Patents
Wittmann's latest patents include the Orbal wastewater treatment process and the Activated sludge wastewater treatment process. The Orbal wastewater treatment process features a series of concentric, annular basins or channels equipped with surface aeration means. In this process, wastewater and recycled activated sludge are mixed in a first channel, utilizing surface aeration and introducing an oxygen-containing gas, such as air, into the lower portion of the zone. This method ensures a complete mix reaction and provides sufficient oxygen to meet the biological oxygen demands of the mixed liquor. The gas is introduced through fine bubble membrane diffusers, producing bubbles with a diameter of less than about 4 mm.
The Activated sludge wastewater treatment process also involves the homogeneous mixing of wastewater and recycled activated sludge in a first aeration zone. An oxygen-containing gas is injected into the lower portion of the zone, maintaining a complete mix reaction and ensuring that the overall dissolved oxygen content remains as close to 0 as possible. The process is further enhanced by sequentially contacting the mixed liquor with an oxygen-containing gas in subsequent aeration zones, clarified, and recycling a portion of the settled sludge back to the first aeration zone.
