Why is the sludge in an aerobic digestion tank stirred and heated during sewage treatment?
Without stirring, oxygen does not get to the majority of the sludge. This makes it anaerobic rather than aerobic. Anaerobic bacteria tend to be nastier, and emit methane, a powerful and explosive greenhouse gas. If the waste is aerobicly treated, it is less likely to absorb oxygen when it is ejected into a local river, and less likely to hurt local wildlife (fish).
What else can I help you with?
What is added to waste during the aeration part of its treatment?
Oxygen is added during the aeration process of waste treatment to promote the growth of aerobic bacteria that break down organic matter in the waste through biological processes. This helps to reduce the organic content and improve the overall treatment of the waste.
What gas released during respiration reactions?
CO2 is produced during aerobic and non aerobic respiration.In kreb cycle CO2 is produced in aerobic respiration.
What is aerobic power?
Aerobic power refers to the maximum amount of oxygen a person can take in during exercise. Aerobic power is also called aerobic capacity.
What caused an aerobic atmosphere during the history of the earth?
The origin of photosynthetic prokaryotes caused an aerobic atmosphere during the history of the earth.
Which enzymes are at work during digestion?
During digestion the enzyme in saliva works on cooked food
When protein compounds are catalyzed what do they do to the chemical reaction during digestion?
Neutralize chemical reactions during digestion
What molecule is used during aerobic respiration?
Cellular respiration can be aerobic and anaerobic. Aerobic respiration requires oxygen, anaerobic respiration does not need oxygen.
What does an organism take from the environment during aerobic respiration?
An organism takes in oxygen during aerobic respiration.
What is produced during aerobic respiration?
During aerobic respiration, oxygen and glucose are used. At the end of the process, water and carbon dioxide are released accompanied by energy.
What are lipids broken down into during the process of digestion?
During digestion, lipids are broken down into fatty acids and glycerol.
What do lipids break down into during the process of digestion?
During digestion, lipids break down into fatty acids and glycerol.
What is one product that is formed during the digestion of triglycerides?
