in waste water treatment some solid contaminants will settle out in settling basins or tanks leaving a pure water supernatant. If the particles are too small to settle either quickly or at all, chemicals (demulsifiers) are added to allow them to agglomerate (or coagulate) into large particles which will separate.
For common waste water treatment process start from filtration of garbage then go through coagulation and flocculation and sedimentation to remove suspense solid. The pretreated water then go through the biological treatment which could be an aerobic treatment or anaerobic treatment. The effluent would go through final filtration - sedimentation before discharge. For a specific waste water treatment, it may involve neutralization, electrodialytic or absorbent to separated out specific contamination such as heavy metal.
It can be done many procedures:- Dilution, filtration, chemical treatment, sedimentation, coagulation aeration etc. Solid waste can be dumped below shallow depth in the earth suface
treatment and disposal of human waste.
It usually depends on different kinds of waste treatment plants but most of them have.
a waste
Ontario's waste goes in landfills of treatment sites.
In the field of water supplies, it is a factor that must be considered in chemical coagulation, disinfection, water softening and corrosion control. In waste water treatment processes pH must be controlled with in range favorable to particular organisms. All these processes are controlled by environmental engineers.
Oxygen is added during the aeration process of waste treatment to promote the growth of aerobic bacteria that break down organic matter in the waste through biological processes. This helps to reduce the organic content and improve the overall treatment of the waste.

House drain ends at the city sewer. City sewer ends at the waste treatment plant. Waste treatment ends at the nearest river.
