How does activated sludge process work
Webconventional activated sludge systems. The unit processes of the SBR and conventional activated sludge systems are the same. A 1983 U.S. EPA report, summarized this by stating that the SBR is no more than an activated sludge system which operates in time rather than in space. The difference between the two technologies is that the WebThe process requires approximately 50% less tank volume and can be prefabricated as a package plant for flows of 0.05 to 1.0 MGD. On the downside, this system is more complicated to control because many common control calculations do not work. Extended Aeration Activated Sludge. Extended aeration does not require primary treatment.
