Advanced control of wastewater treatment plants
<< TO BE UPDATED, PLEASE VISIT AGAIN >>
 
My contribution in this European-founded project has been the development of software sensors in the water line of a waste water 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.
