What is the main purpose of water filtration?

The primary purpose of water filtration is to remove dirt, sediment, and some bacteria from water. Filtration systems are designed to physically eliminate particles from water, which can include larger contaminants like sand and silt, as well as smaller microorganisms. By using various filtering materials, these systems can improve the clarity and safety of water, removing many harmful substances that may pose health risks.

While treating water does aim to improve quality, complete purification (as suggested by the idea of removing all contaminants) is often challenging and may not be feasible with all filtration methods. Instead, many filtration systems are focused on providing a practical solution by significantly reducing the presence of dirt and certain bacteria to ensure that the water is safe for consumption and visually clear.

This approach supports public health by minimizing exposure to potentially harmful agents while acknowledging that some filtration methods may not eliminate all contaminants completely. Hence, the emphasis on removing dirt and some bacteria is central to understanding the main purpose of water filtration.
