Answer 2

Answer:

Primary sludge is a result of the capture of suspended solids and organics in the primary treatment process through gravitational sedimentation, typically by a primary clarifier. The secondary treatment process uses microorganisms to consume the organic matter in the wastewater. Sewage sludge treatment describes the processes used to manage and dispose of sewage sludgeproduced during sewage treatment. Sludge is mostly water with lesser amounts of solid material removed from liquid sewage.
