SUMMARY:

The activated sludge system is a wastewater treatment method, capable of removing water pollutants using aerobic bacteria metabolism. The oxygen uptake rate (OUR) is an important parameter to the evaluation and monitoring of the activated sludge system, since it allows evaluating the biodegradation of polluting organic matter. In this work,
we propose a method to measure OUR based on the architecture of the first order sigma delta modulator in the biological domain. In this method, the operational functions of the sigma delta modulator will be performed by biological processes and electronic circuits. The proposed method has some advantages over existing OUR measurement methods. When compared to the classical method, it improves the dynamic response, decreases and
fixes the sampling time; when compared to the PWM method, it introduces the benefits of noise modeling and oversampling. The performance of the proposed model is demonstrated through simulations.
