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.

The different characteristics of democracy are related to the types of democracy that currently exist.
These types and their characteristics are:
Direct democracy: This democracy allows all citizens of a region to participate directly in the establishment of policies. This type of democracy was exercised in Athens and allowed any citizen (women and slaves not to be considered) to be able to present a bill, in addition to voting on the bills presented. Not only that, citizens could also participate directly in the region's legislative and executive power.
Representative democracy: It is the type of democracy used in republican and parliamentary countries. it is the most common type today and allows citizens to participate in the formation of policies indirectly, through the choice of their representatives, through the election of those who form the legislative and executive power.
Participatory democracy: It can be considered a semi-direct democracy. This is because it allows citizens to vote for their representatives, but it also allows citizens to participate directly in their country's governmental decisions.
