On-line control of biological nutrient removal processes in practice: a cost-benefit analysis.
On-line control is able to boost process efficiency and optimise effective capacity of nutrient removal plants. In this paper, costs and benefits of on-line control are presented and economical feasibility is analysed using a simple economical cost-benefit analysis. These concepts are illustrated by a number of full-scale case studies. The on-line control of ferric dosage is illustrated by the case of the Lommel WWTP, and the Harelbeke WWTP and Houthalen WWTP illustrate advanced on-line control of aeration for nitrogen removal.
