What size of particulate matter is removed by the multimedia filter?

The correct answer highlights that a multimedia filter is typically designed to effectively remove particulate matter sized around 10 microns. Multimedia filters use layers of different media with varying sizes and densities, which allow them to capture a range of particle sizes as water flows through. The top layer usually consists of coarse media that captures larger particles, while finer layers beneath trap smaller particles, thus improving overall water clarity.

Particulate matter larger than 10 microns, such as sand or larger sediment, may be initially filtered out by coarser media, but 10 microns is generally regarded as a standard benchmark for the minimum size targeted during the filtration process. Smaller particles can pass through without proper filtration or additional treatment processes, making it essential that the correct filter media and configuration are used to optimize performance for specific water treatment needs.
