Final answer:
Option D.
The process that involves removing solids and impurities from wastewater without necessarily making the water potable is known as wastewater treatment.
Step-by-step explanation:
The process of water reclamation is designed to remove solids and impurities from wastewater, but it does not necessarily result in potable, or drinkable, water.
To identify the option that refers to treatment of wastewater rather than converting non-potable water into drinking water, we need to understand the different processes described by each option provided:
- Water desalination - Removes salt from seawater, resulting in potable water.
- Water purification - Involves multiple processes to make water safe for drinking, including filtration, disinfection, and removal of contaminants.
- Water filtration - Is a part of the purification process which can also be applicable to non-potable reclamation scenarios.
- Wastewater treatment - Cleans wastewater to make it safe for returning to the environment or for reuse in non-potable applications.
Wastewater treatment most closely matches the description of the water reclamation process provided in the question, as it involves treating water to remove pollutants for various reuse applications that do not require potable standards.
Therefore, the correct option that describes a process that removes solids and impurities but does not necessarily make water potable is D) Wastewater treatment.
Please mention correct option in final answer: D) Wastewater treatment
