Domestic sewage from washrooms and toilets is taken to sewage treatment facilities which can range in size and complexity from septic tanks to tertiary treatment systems.
The simplest of municipal treatment systems is simply a series of sewage lagoons which hold the total volume of sewage allowing lumps tp settle and the organics to be removed by natural oxidation and bacterial processes. After holding for about a year the sewage is released, generally at the time of high spring flows, to a local watercourse. There are often two lagoons in a system one fills while the other sits idle and dry. The full lagoon is taken off line when full, the second lagoon fills while the first ages. The full lagoon is emptied. When empty, the flow is once more diverted to it while the (now full lagoon ages until it discharged, restarting the cycle.
The steps in the processes at larger treatment plants are:
Primary Treatment (De Lumping)
The incoming sewage is comminuted (blended) to reduce large lumps.
The fine particles are put in a separator where floating material is skimmed off for alternate disposal, settleable material is removed for alternate disposal. The water in the middle is either discharged or sent to Secondary Treatment
Secondary Treatment (Removing fine particulates and dissolved organics)
The fluid from the Primary system is put into an aerated basin where the sewage is mixed with air. Microbes in the sewage eat the dissolved organics.
The mixture of uneaten particles and microbes is transferred to a seperator where the microbes settle and are collected. They are divided. Part of them are sent back to eat more sewage, part are sent to disposal This sludge is transferred to a separation tank where
A portion of the sludge's are removed for disposal in anaerobic digesters.
Anaerobic digesters which convert the microbe bodies and particulate to methane gas to power the treatment processes.
The solid free liquid from the separator is discharge to the environment or sent to Tertiary treatment.
An option at this stage is to adjust the bacteria colony for nitrogen removal.
Tertiary Treatment (A final polishing)
To remove traces of organics, odours, viruses and very fine particulates some sewage treatment plants provide another stage of treatment. This can include chlorination, filtration or even reverse osmosis.
Typically waste water is pumped to a reclimation plant. When it enters the plant, it is placed into a reclimation pond where the waste settles out. It is then pumped through various filtration and anerobic bacteria processes which further removes waste. Finally it is passed through a bed of ultraviolet lamps to kill any remaining microorganisms. The cleaned water is then pumped back into water system.
well theres lots of waters in the cities its schools,homes,stores,

What is treated water?
this is water that comes from a river or a lake and goes through a treatment plant (this plant has all the chemicals and machinery) then once it is treated it then flows into people's home through the main pipes in the city.
Where does colville get its water?
Colville gets its water primarily from Deep Creek, which is treated at the city's water treatment plant before being distributed to residents. Additionally, some water may come from groundwater wells within the city.
What percentage of the waste water in Mexico city is purified now?
I guess you mean "treated." Only 15% of waste water is treated. The remaining is reused in irrigated agriculture, including alfalfa, barley, wheat and corn.
Is well water the same as tap water?
Well water and tap water are not necessarily the same. Tap water typically comes from a municipal water supply that may include water from wells, rivers, or reservoirs, which is then treated to meet safety standards. Well water, on the other hand, comes from a private well on a property and is not typically treated by a municipality. Quality and safety of well water can vary depending on location and maintenance of the well.
How much waste water is Mexico City currently treating?
Mexico currently treats only 40% of its municipal wastewater. Only 10% of the municipal wastewater is treated currently in the Greater Mexico City Area and none of the municipal wastewater in Guadalajara, is currently treated
Can bromine treated water be mixed with chlorine treated water?
It is generally not recommended to mix bromine-treated water with chlorine-treated water as it can result in a chemical reaction that can produce harmful byproducts. It is best to use one type of sanitizer consistently in your water treatment system.
What is better water tap or bottled?
It all depends on where you live. if you live in a country/rural area the tap water is most likely from a well or storage facility in the area. The water is not as well treated as city water so bottled water is better because it is cleaner and better for your health. In the city its all the same thing.
What is the difference between natural water and treated water?
the difference is that natrual water has not been treated and has nothing in it to make it taste the way it tastes but treated water on the other hand probaly has something in it like sugar or something else
The harm of water?
Treated tap water is not dangerous (If you do not get into it).
Where is karkh water treatment plant?
The Kharkh Water Treatment Plant is located about 30 kilometers north of Baghdad on the west side of the Tigris River, from which it takes the water to be treated. Kharkh provides about 40 percent of treated, potable water for the city of Baghdad.
What is the water sources in Garfield heights?
Garfield Heights primarily sources its water from Lake Erie, which is treated and distributed through the Cleveland Water Department. Additionally, the city has groundwater wells that supplement its water supply during peak demand periods.
What is municipal water?
This is treated water (drinking water) distributed in a town.
