What are the most important characteristics of filter media?

The most important characteristics of filter media are particle size and uniformity coefficient. Particle size is critical because it directly influences how effectively the filter can remove particles from water. Smaller particles tend to be trapped more efficiently, while larger particles may pass through the filter.

The uniformity coefficient provides insight into the size distribution of the filter media. A lower uniformity coefficient indicates a more consistent particle size, which typically leads to better filter performance. Conversely, a higher uniformity coefficient suggests a wider range of particle sizes, which can create gaps that allow smaller particles to pass through or lead to uneven filtration rates.

While other characteristics like color, shape, weight, and texture can have some influence on filter performance, they are less critical than particle size and uniformity coefficient for ensuring effective filtration. Viscosity and density are properties more relevant to fluid dynamics than to the effectiveness of filter media in water treatment processes.
