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 basic doctrines of early Buddhism, which remain common to all Buddhism, include the four noble truths: existence is suffering (dukhka); suffering has a cause, namely craving and attachment (trishna); there is a cessation of suffering, which is nirvana; and there is a path to the cessation of suffering, the eightfold path of right views, right resolve, right speech, right action, right livelihood, right effort, right mindfulness, and right concentration. Buddhism characteristically describes reality in terms of process and relation rather than entity or substance.

Explanation:
Accounting profit is the difference between total revenue earned and total explicit costs incurred in the process of production. Explicit cost is the direct cost involved in the production process.
The economic profit is the difference between the total revenue earned and the total explicit as well as the implicit cost incurred. The implicit costs are the indirect cost or opportunity cost of production.
Since accounting profit does not take into account implicit costs, it is greater than economic profit.
