Abstract

PURPOSE: To control amount of activated sludge kept in the settling basin, by sampling a portion of liquid to be treated in aeration tank, detecting imaginary interface height after measuring the interface settling value, and supplying its correction factor and value of operational condition to operational unit for computing the same.
