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.
