Primary TreatmentnAs sewage enters a plant for treatment, it flows through a screen, which removes large floating objects such as rags and sticks that might clog pipes or damage equipment. After sewage has been screened, it passes into a grit chamber, where cinders, sand, and small stones settle to the bottom.,
As waste water flows through the ground, the nitrogen from urine and other wastewater content is typically converted to nitrate, which is reactive. Nitrate travels through the ground water until it eventually flows to surface waters or drinking water wells.
The number of visitors to national parks hit an all-time high of more than 330 million in 2016. The math pretty much stinks: Humans produce up to a pound of poop per day and human feces take about a year to biodegrade.

The treated wastewater is released into local waterways where it's used again for any number of purposes, such as supplying drinking water, irrigating crops, and sustaining aquatic life.
Chlorine is added to raw water to eliminate algae and other forms of aquatic life from the water so they won't cause problems in the later stages of water treatment.Jan 23, 2017
Majorly, four methods of sewage water treatment are followed – physical, biological, chemical, and sludge water treatment. By following these methods, the wastewater is disinfected from all the sewage materials and converted into treated water that is safe for both human usage and the environment.
The wastewater flows through bar screens to remove trash and debris, then slowly moves through a grit tank where sand and heavy particles settle and are removed.
There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment.Dec 6, 2018
