An experimental system for the control of wastewater treatment plants

Customer	Domžale-Kamnik wastewater treatment plant
Duration	2002 - 2003
Objectives	Ensure stable process operation, improve the efficiency of wastewater treatment, reduce the operational costs by means of savings of energy and reactants.
Description	Control of ammonia concentration in aerobic reactors
Innovation	Aeration control based on online measurements of the ammonia concentrations in the influent and in the aerobic reactor control algorithms combining feedforward and feedback control.
Benefits	Lower ammonia peaks at the effluent along with a 45% reduction of the electrical energy needed for aeration.
