What is the first stage of water treatment?
The first stage, or primary treatment, is designed to remove large debris and solids from the water . The water is pumped into sedimentation tanks, where solids and suspended sediment is allowed to settle out of the bottom, and scum rises from the top. This material is removed and incinerated or sent to a landfill.
How much solids are removed from wastewater?
Primary treatment removes about 60 percent of solids from wastewater. If you live in a rural area, your house probably has a septic tank to treat the waste from your own house. Septic tanks act similarly to sedimentation tanks in WWTPs, by allowing large solids to settle to the bottom and scum to rise to the top.
Why is water aerated?
The water is aerated (or shaken up) to release dissolved gases such as hydrogen sulfide. Aeration also replenishes oxygen, which is consumed by decaying organic matter found in wastewater. Bacteria are also used at this stage to consume nutrients and organic materials.
Why is it important to clean wastewater?
It is important for wastewater effluent to be virtually free of bacteria to prevent the degradation of water quality in the receiving body of water. Unfortunately, only a handful of the most modern and expensive WWTPs in America discharge close-to-pristine effluent.
What is tertiary treatment?
Tertiary treatments are applied where constituents of concern remain after primary and secondary treatment. The final stage of treatment is disinfection, which removes bacteria, viruses and other microorganisms before the water is discharged back into the environment.
Does chlorine kill bacteria?
For more information, see the Nutrient section. Chlorine – If chlorine is used to remove bacteria during treatment, it should be chemically removed before the water is discharged to the environment. Large concentrations of chlorine are toxic to many aquatic species and can kill beneficial bacteria in the environment.
What is a WWTP permit?
WWTPs are required to monitor their effluent (treated wastewater discharged to the environment). The WWTP must acquire a permit allowing them to discharge the treated wastewater, which establishes limits for certain constituents.
