  • Biological nutrient removal process control system
    Patent number: 10407330
    Abstract: A process for biological nutrient removal including: receiving fluid having sludge in a basin through a sludge inlet; activating an aeration system based at least partially on a time of day; periodically measuring a potassium level of the fluid; determining a potassium rate of change based on the periodic measurements of potassium level; and deactivating the aeration system based at least partially on the determined potassium rate of change. A system for biological nutrient removal is also disclosed.
    Type: Grant
    Filed: October 11, 2017
    Date of Patent: September 10, 2019
    Assignee: Xylem Water Solutions U.S.A., Inc.

  • Optimized process and aeration performance with an advanced control algorithm
    Patent number: 9475715
    Abstract: An automatically controlled wastewater treatment process can include automatically controlling nitrification and denitrification capacity in a water source. The nitrification and denitrification capacity can be automatically controlled simultaneously. In addition, the wastewater treatment process can also include automatically controlling solids retention time (SRT) and biological phosphorus removal in a water source as well as automatically controlling the removal of water from a containment device.
