Abstract
The operation of an anaerobic methanogenic filter is controlled by measuring the rates at which oxygen demand (O.D.) is fed to the anaerobic filter and at which methane is generated by the filter, estimating therefrom the O.D. of the effluent of the anaerobic filter and controlling the feed rate to the anaerobic filter in accordance with that estimated value. Also disclosed is a means for eliminating long term bias that may be present in the signals fed from sensors to the circuit used for estimating the value of a variable of a process.
