Latest Patents

One of his notable inventions is the Orbal wastewater treatment process. This process involves a series of concentric, annular basins or channels equipped with surface aeration means. In this system, wastewater and recycled activated sludge are mixed in a first channel through a combination of surface aeration and the introduction of an oxygen-containing gas, such as air. This method ensures that sufficient oxygen is supplied to meet the biological oxygen demands of the mixed liquor. The gas is introduced via fine bubble membrane diffusers, producing bubbles with a diameter of less than about 4 mm. The mixed liquor is then oxidized sequentially in subsequent channels, maintaining optimal conditions for effective treatment.

Another significant patent by Smith is the Activated Sludge Wastewater Treatment Process. In this process, wastewater and recycled activated sludge are mixed in an aeration zone by injecting an oxygen-containing gas into the lower portion of the zone. This method also utilizes fine bubble membrane diffusers to maintain solids in suspension and ensure adequate oxygen levels. The mixed liquor is subsequently treated in additional aeration zones, clarified, and a portion of the settled sludge is recycled back to the first aeration zone.
