| D53 - Evaluation report of the optimal control strategies for the CAS-MBR Dual 1 concept | |
| Project | AMEDEUS |
| Date | 6.6.2009 |
| Abstract | The Evaluation Report of the Optimal Control Strategies for the CAS-MBR Dual 1 Concept encompasses an evaluation of a novel model-based feedforward control that the Aquafin team has developed, implemented and tested on a full scale at the Schilde MBR wastewater treatment plant (WWTP), Belgium. The theoretical basis of the controller is described in the Deliverable D52. Because of the current severe pollutant overloading, the objective of the controller is to make the best possible use of the capacity available in existing tanks for nitrogen removal. The feedforward action is based primarily upon two water quality signals, namely the ammonium and the suspended solids concentrations, measured on-line in the WWTP influent. The model which the algorithm is based on, is a simplified version of the International Water Association Activated Sludge Model 2D (ASM 2D). Iron chloride is used as a temporary expedient to relieve the overloaded CAS unit by improving the efficiency of the primary sedimentation (enhanced primary clarification, or EPC). |
