Abstract
Hydraulic efficiency and nitrogen control of applied secondary municipal wastewater were evaluated for four separate operating schedules. Four 1.8 meter diameter by 2.45 meter deep lysimeters containing two different soil types having high infiltration rates were used in the evaluation. The evaluations assessed the total nitrogen mass passing through the lysimeters during loading cycles, including flushed-through spikes of high nitrate-laden soil water. Total nitrogen reduction calculations indicate an operating sequence of one-day flooding and one-day drying was the most efficient for total nitrogen removal but lightly less efficient hydraulically than three days flooding and four days drying.
