Wastewater treatment, the removal of impurities from wastewater before it reaches aquifers or natural bodies of water. Wastewater treatment is a major element of water pollution control. Learn more about the types of wastewater treatment systems, the technologies used, and the history of treating wastewater.
Wastewater treatment is a process which removes and eliminates contaminants from wastewater. It thus converts it into an effluent that can be returned to the water cycle . Once back in the water cycle, the effluent creates an acceptable impact on the environment.
The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
Wastewater treatment protects human and ecological health from waterborne diseases. Since the early 1970s, effluent water quality has been improved at Publicly Owned Treatment Works (POTWs) and other point source discharges through major public and private investments prescribed by the Clean Water Act (CWA).
There are two main levels of wastewater treatment: primary and secondary treatment. In the primary stage, solids are allowed to settle and be removed from wastewater. The secondary stage uses biological processes to further purify wastewater.
Wastewater is water that has been used and must be treated before it is released into another body of water, so that it does not cause further pollution of water sources. Wastewater comes from a variety of sources. Everything that you flush down your toilet or rinse down the drain is wastewater.
Wastewater treatment technologies and processes are designed to break down bodily waste and toilet paper ONLY. If it Can’t Flow, it Overflows. An overflow is a very nasty, costly mess that has to be cleaned up and paid for immediately.
Wastewater treatment refers to the physical, chemical, and biological processes used to remove pollutants from wastewater before discharging it into a waterbody. Since the Clean Water Act was issued in 1972, there are now more than 16,000 publicly owned wastewater treatment plants in operation in the United States.
The basic function of wastewater treatment is to speed up the natural processes by which water is purified. There are two basic stages in the treat-ment of wastes, primary and secondary, which are outlined here. In the primary stage, solids are allowed to settle and removed from wastewater. The secondary stage uses biological processes to
