What stage of sewage treatment produces methane?
Methane is emitted during the handling and treatment of municipal wastewater through the anaerobic decomposition of organic material. Most developed countries rely on centralized aerobic wastewater treatment systems to collect and treat municipal wastewater.
Which potential source of water pollution is a nonpoint source quizlet?
Nonpoint pollution sources are broad, diffuse areas, rather than points, from which pollutants enter bodies of water. Examples include runoff of chemicals and sediments from cropland, livestock feedlots, clear-cut forests, urban streets, parking lots, lawns, and golf courses. What is the Clean Water Act?

There are three types of wastewater, or sewage: domestic sewage, industrial sewage, and storm sewage. Domestic sewage carries used water from houses and apartments; it is also called sanitary sewage. Industrial sewage is used water from manufacturing or chemical processes.
What is BOD and COD?
The biochemical oxygen demand (BOD) represents the amount of dissolved oxygen (DO) consumed by biological organisms when they decompose organic matter in water. The chemical oxygen demand (COD) is the amount of oxygen consumed when the water sample is chemically oxidised.
What is anaerobic sewage treatment?
