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 .

CLEAN WATER CURRICULUM Background Information For Teachers 5 Wastewater What Is Wastewater? Wastewater is water that goes down drains in industries, homes, and public buildings. Less than 1 percent of wastewater is waste; more than 99 percent is water. Wastewater in the HRSD service area is returned to local waterways after it is treated. In our area, treated wastewater is not returned to .
