Wastewater treatment
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.
What is the purpose of wastewater treatment facilities?
Summary. The main goal of wastewater treatment facilities is to protect humans and the ecosystem from harmful and toxic elements found in wastewater. Water treatment facilities were designed to speed up the natural process of purifying water because the natural process is overloaded.
Why do we need water treatment facilities?
Water treatment facilities are designed to speed up the natural process of purifying water. With billions of people and even more wastewater, the natural process is overloaded. Without wastewater treatment, the amount of wastewater would cause devastation, as it still does today in developing countries. Globally, over 80 percent of all wastewater is discharged without treatment. 1 In the countries that do have water treatment facilities, they use various methods to treat water with one common goal: purify water as much as possible and send it back into the environment to keep humans and the Earth safe and thriving.
Why is wastewater important for the ecosystem?
