ABSTRACT:
In the operation of a recycling anaerobic filter for treating aqueous waste streams, the rate of production of methane is measured continually at frequent intervals and the COD feed rate is varied to maintain a predetermined, timed, relationship between that varied feed rate and the measured methane production rate.
