Question

the aerobic digestion of sewage is used to produce?​

Answer 1

Answer:

Aerobic digestion of sewage is used to produce biofuels. The fuel obtained from biomass is called biofuel.

Explanation:

• It is well known that as a biological process, aerobic sludge digestion occurs in the presence of oxygen and in this process the bacteria in activated sludge consume organic matter with oxygen and convert them into carbon dioxide.
• Biofuel, any fuel that is derived from biomass – i.e. plant or algae material or animal waste.
• Since such feedstock material can be easily replenished, biofuels are considered a source of renewable energy, unlike fossil fuels such as petroleum, coal and natural gas.

Answer 2

The aerobic digestion of sewage is used to produce biofuels.

About bio-fuels:

• Biofuel is a type of fuel that is created quickly from biomass, as opposed to the lengthy natural processes that result in the development of fossil fuels like oil.
• Some people conflate the terms "biomass" and "biofuel" since biomass may be used directly as fuel.
• Green diesel, which is produced from algae and other plant sources, biogas, and ethanol are some examples of biofuels. Ethanol is frequently produced from maize in the United States and sugarcane in Brazil (methane derived from animal manure and other digested organic material).

What may be created by sewage's aerobic digestion?

• The biological process of aerobic sludge digestion requires an atmosphere that is high in oxygen.
• Bacteria in activated sludge consume organic matter and oxygen while producing carbon dioxide as a byproduct.
• When bacteria consume (digest) organic materials without the presence of oxygen, anaerobic digestion generates biogas (or oxygen).
• The main components of biogas are methane (CH4) and carbon dioxide (CO2), with very small amounts of other gases and water vapour.
