Which of the following is NOT one of the main goals of water treatment?

The main goals of water treatment revolve around ensuring the safety, quality, and aesthetic acceptability of drinking water. Providing safe drinking water is a primary objective, as it protects public health by removing contaminants and harmful substances. Eliminating harmful microorganisms is also crucial, as these pathogens can lead to serious health issues if not addressed. Improving aesthetic properties, such as taste, odor, and color, is important to ensure consumer satisfaction and encourage people to drink enough water.

Reducing water temperature, however, is not considered one of the main goals of water treatment. While temperature regulation can be relevant in certain contexts, such as preventing thermal pollution in ecosystems or maintaining comfortable water temperatures in industrial processes, it does not directly relate to the core objectives of removing contaminants or improving the safety and quality of drinking water for human consumption. Therefore, this option stands out as not aligning with the primary goals of water treatment.
