Background and description
The "Optimised Plant", the latest TwinPlant module, provides users with advice on optimal settings (set-points, PID parameters) for aeration controllers. These settings allow users to optimise plant performance based on a set of custom-defined objectives (e.g. effluent quality, energy efficiency, carbon footprint, operational costs), alone and in combination. Optimal settings are identified for a pre-defined forecast period (up to 48 hours in the future), allowing for continuous and proactive improvement of process performance in a wastewater treatment plant.
EXAMPLE: “Setting up aeration control optimization and visualizing optimal settings”.
This example presents an optimisation experiment, through which the optimal ammonium (NH4-N) set-point for aeration is identified. The optimisation experiment is performed every 6 hours, i.e. a newly optimised set-point is provided four times every day while considering loading and process dynamics in the wastewater treatment plant.
The "Optimised Plant" guides the user through the following steps:
Step #01 - Visualize a summary of the latest optimised set-point values for different key performance indicators (KPIs) - Fig. 1
A summary of the last optimised set-point values for different KPIs, alone and in combination (“Multi-Objective”), is provided together with a comparison with the currently used set-point (Fig. 1).

Step #02 - Gather historical view of optimised set-points - Fig. 2
A historical view of optimised set-points for different KPIs can be visualised, allowing for a comparison with the currently used (i.e. baseline) set-point value (Fig. 2).

Step #03 – Compare performance and determine savings - Fig. 3
For each KPI, a comparison between the current and optimised performance is provided together with the quantified saving potential.
