Contact stabilization activated sludge
WebSewage treatment in Austria occurs mainly by the activated sludge system. Conventional aerobic sludge stabilization is mostly used in WWTPs smaller than 20,000 PE, while anaerobic sludge stabilization via digestion is the more frequently applied method in WWTPs larger than 20,000 PE . Other designs are rare, with most cases being … http://www.owp.csus.edu/glossary/contact-stabilization.php
