Summary:A dual-level control system for operating a wastewater treatment apparatus may include at least a primary level of control including a measurement of a process control variable to arrive at a dissolved oxygen (DO) set point and a primary mode of operating parameters including primary aeration chain timer and primary aeration chain grouping designed to achieve the DO set point when the DO set point falls within a predetermined range of values; and at least a secondary level of control to arrive at a secondary mode of operating parameters including secondary aeration chain timer and secondary aeration chain grouping designed to achieve a desired concentration of effluent total nitrogen when the DO set point either falls to or below a minimum value or rises to or above a maximum value. The process control variable may be, for example, an effluent concentration of NH
