Aerated Lagoon Design Calculation . Where, t = temperature of pond at design (winter) 0 = temperature factor, = 1.036 k = reaction rate at design temperature k20=reaction rate at 20 degrees celcuis taken together. Most lagoons, on the other hand, tend to be partial mix, meaning that there is no set airflow.
Aerated Lagoon Enhancements for NPDES Compliance from www.snyder-associates.com
A surface aerator in a deep lagoon of 15 feet or more will struggle to provide enough mixing than it would in a shallow lagoon of 5 feet or less. The lagoon should be as deep as practicable, as greater depth provides improved heat retention. Post processing of the results by calculating the local average residence time.
