The final treatment of wastewater in the united states normally involves treatment with Chlorine to make it safe.
The final stage of the wastewater treatment process, which is when it is often carried out in most treatment plants, can also include chlorination. The primary goals of this chlorine addition are water disinfection and maintaining chlorine residuals that will stay in the water as it moves through the distribution system.
In the US, wastewater treatment facilities treat over 34 billion gallons of wastewater per day. Human waste, food waste, and some soaps and detergents all contribute nitrogen and phosphorus to wastewater. Once the water has been cleansed to the standards required and observed by state and federal authorities, it is often released into a nearby water body.
