Advanced Control of Wastewater Treatment Plants

This page is being updated — please visit again.

My contribution in this European-funded project has been the development of software sensors in the water line of wastewater treatment plants (WWTPs), which serves for monitoring the ammonia concentrations in the aerobic tanks of the plant line and in the anoxic tank. In addition, the software sensor serves to track the maximum nitrification rate. Specifically, Extended Kalman filter is derived and shown the Kalman filter to a much broader class of non-Gaussian distributions. The filter has several desirable properties, such as its ability to preserve statistical relationships in the prior state and converge to highly accurate observations [1].

Some projects in this field where I have been working on:

DARROW – Making wastewater treatment more sustainable and efficient using a data-driven AI solution

DARROW aims to build a data-driven AI solution to optimise resource recovery from wastewater by making wastewater treatment plants more autonomous and energy efficient.

Award institution: European Union’s Horizon Europe research and innovation programme within the project DARROW (grant agreement Nº 101070080)

Plot of the process covariance values over discrete time — Process covariance matrix [1]

Plot of the Kalman gain values converging over discrete time — Kalman gain values during convergence for state model covariance [1]

Block diagram: the real process and the extended Kalman filter, each with a state model and output equations, linked by the Kalman filter gain — Proposed methodology for the application of the extended Kalman filter [1]
