What is the primary function of a water filtration system?

The primary function of a water filtration system is to remove contaminants from water. This process is essential for ensuring that the water is safe for consumption and other uses. Filtration systems utilize various methods, such as physical barriers, chemical processes, and biological interactions, to eliminate harmful substances, including sediments, bacteria, chemicals, and other pollutants.

By effectively filtering out these contaminants, the system not only improves the water's clarity and taste but also protects human health and the environment. The importance of this function cannot be overstated, as access to clean water is critical for public health and is a key aspect of sustainable water management.

The other options reflect different functions that are not the primary aim of a water filtration system. While increasing water temperature, introducing nutrients, and regulating water pressure are important aspects of water management, they do not encompass the primary purpose of filtration, which is focused on purification and safety of water.
