Answer 1

Mud and sand settle in a tank called a grit chamber. Later, this material, known as grit and screenings, is taken to a landfill for environmentally safe disposal. The sewage then flows to primary settling tanks where up to 60% of the solids in the waste stream settle out as a mixture of sludge and water.

Answer 2

Answer:

Sewage, or domestic/municipal wastewater, is a type of wastewater that is produced by a community of people. It is characterized by volume or rate of flow, physical condition, chemical and toxic constituents, and its bacteriologic status. Sewage is pumped from buildings and homes through pipes that transfer the waste to filters that separate large objects from the sewage water. Large items can include plastic, logs, and other materials. Sewage then flows into tanks where solids in the wastewater will separate into sludge and water.
