What is the percentage of dissolved oxygen in sewage?
The percentage of dissolved oxygen in sewage can vary depending on factors such as temperature, organic load, and biological activity. Typically, sewage contains very low levels of dissolved oxygen, often approaching 0% in areas with high levels of organic pollutants due to microbial respiration and decomposition processes.
Why does raw sewage lower dissolved oxygen?
Raw sewage contains organic matter that serves as a food source for bacteria. As bacteria consume the organic matter, they use up oxygen during the decomposition process. This results in a decrease in dissolved oxygen levels in the water where the raw sewage is discharged.
What can A body of water can be depleted of its oxygen by .?
A body of water can be depleted of oxygen by excessive nutrient runoff (eutrophication), which leads to algal blooms that consume oxygen as they decompose. Pollution from industries or sewage can also introduce harmful substances that reduce oxygen levels in the water. Additionally, temperature changes and natural processes like decomposition can contribute to oxygen depletion.
Why raw sewage could decrease oxygen?
Raw sewage contains organic matter that can be broken down by bacteria, using up oxygen in the water during the decomposition process. This can lead to a decrease in oxygen levels in the water, potentially causing harm to aquatic life and disrupting the ecosystem.
Name some oxygen demanding waste?
Some examples of oxygen demanding waste include sewage, organic matter from agricultural runoff, and paper or pulp mill waste. These substances consume oxygen in water bodies as they decompose, leading to decreased oxygen levels that can harm aquatic life.

How is sewage purified?
Sewage purification in natural way:Sewage is purified by microorganisms present in sewage in an environmentally favourable condition to them. Microorganisms purify sewage either in the presence of oxygen or in the absence of oxygen also. When dissolved oxygen is completely utilised resulting no dissolved oxygen in the sewage, sewage attains a stingy condition commonly known as septic condition.
Why raw sewage could decrease oxygen?
Raw sewage contains organic matter that can be broken down by bacteria, using up oxygen in the water during the decomposition process. This can lead to a decrease in oxygen levels in the water, potentially causing harm to aquatic life and disrupting the ecosystem.
What are words that rhyme with problem and have to do with sewage?
'Flem' - from someone's throat that they spit out into the toilet and flush down which then enters the sewage system.
How can sewage lead to the death of fish in rivers?
Sewage can deplete oxygen levels in rivers as bacteria breakdown the waste, causing fish suffocation. It can also introduce harmful chemicals and pathogens into the water, leading to fish mortality. Additionally, sewage can disrupt the natural balance of the ecosystem, impacting fish health and survival.
What happens when drinking water get mixed with sewage?
it would taste pretty bad because the oxygen levels in the water would decrease making it less sterile to drink
What happens to the concentration of oxygen in the water when the sewage is added?
The concentration of oxygen decrease.
What happens to the concentration of oxygen in water when the sewage is added?
The concentration of oxygen decrease.
What are the influences of sewage on the river habitat?
The primary influence of sewage on the river habitat is an massive increase in bacteria levels. This can rapidly kill a variety of wildlife and increase algae levels.
Name some oxygen demanding waste?
Some examples of oxygen demanding waste include sewage, organic matter from agricultural runoff, and paper or pulp mill waste. These substances consume oxygen in water bodies as they decompose, leading to decreased oxygen levels that can harm aquatic life.
