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.
