摘要: The measurement and utilization of the oxygen uptake rate (OUR), or respiration rate, is very important in biological wastewater treatment process. It provides information about activity can indicate presence toxic elements able to corrupt system. An alternative lack OUR sensors use computer codes as software for estimation respirometric activity, based on dissolved (DO) measurements. In this paper estimated using Kalman Filter a sensor DO concentration controlled by aerators on-off type triggered pulse wide modulation. Simulation experimental estimations are performed bench scale aerobic reactor.
