Which of the following is true of sewage treatment plants in the United States? They release wastewater before solids are removed from the sewage. They use stormwater runoff to assist in the treatment process.,
Which is a type of wastewater?
Once treated, sewage sludge is then dried and added to a landfill, applied to agricultural cropland as fertilizer, or bagged with other materials and marketed as “biosolid compost” for use in agriculture and landscaping.
How is human waste typically treated in rural areas?
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.
Which is an effect of eutrophication?
Septic systems are underground wastewater treatment structures, commonly used in rural areas without centralized sewer systems. They use a combination of nature and proven technology to treat wastewater from household plumbing produced by bathrooms, kitchen drains, and laundry.Jul 2, 2021
How does sewage cause eutrophication?
The known consequences of cultural eutrophication include blooms of blue-green algae (i.e., cyanobacteria, Figure 2), tainted drinking water supplies, degradation of recreational opportunities, and hypoxia.
Which is most likely to create eutrophic areas?
The bigger problem is that raw sewage causes eutrophication, which is an increase in the concentration of chemical elements required for life. Think natural systems on steroids. The nitrates, phosphates and other organic matter found in human waste serves as a food for algae and bacteria.Mar 15, 2018
Which of the following will result in accelerated eutrophication when?
Causes of accelerated eutrophication: Runoff of fertilizers from the nearby field to the water body causes algal bloom which leads to eutrophication. Sewage and industrial effluents increase the temperature and BOD of the water body, thereby causing increased biological activity, leading to algal blooms.
What is the first step of treating wastewater at a municipal sewage treatment plant?
What is the first step of treating wastewater at a municipal sewage treatment plant? Pathogens are killed with ultraviolet light or chemicals. Water is removed from sludge. Water undergoes aeration to reduce offensive odors.
Which of the following will result in cultural eutrophication when introduced into streams lakes?
Human-induced eutrophication of freshwaters, also called cultural eutrophication, is largely a result of increased phosphorus inputs from sources such as agricultural fertilizers or partially treated sewage.
