Does anyone have experience with Controlling Dissolved Oxygen for wastewater. We are trying to generate ladder logic to modulate blower valve positions, which will control the D.O Level in the aeration tanks. We have used PID control before but that doesnt seem to work to well. We thought of using a timer to control the signal to the valve. We've done this to allow the process to"catch up" with the changes in valve position.
Does anyone have any ideas or solutions??????
