POTENTIAL USE OF STEP FEED CONTROL USING THE BIOMASS IN THE SETTLER

In spite of the widespread availability of step feed configurations in activated sludge systems, little use been made of their control poten tial. The main aim of this study is to provide a better understanding of applying step feed control considering the role of biomass activity in the settler. The control strategy was evaluated by simulating the dynamics of an activated sludge system, The model contains both biomas s activity in the settler and step feed capabilities. The model and th e strategy then have been evaluated against pilot scale and full scale experimental data.
