Secondary treatment is the second stage in wastewater treatment systems in which bacteria consume the organic material in wastewater. Secondary treatment processes can remove up to 90 percent of the organic matter in wastewater using biological processes. The most common conventional methods to achieve secondary treatment are “attached growth .
