What is filter media classified by?

Filter media are primarily classified by their uniformity coefficient, which is a measure of the distribution of particle sizes within the media. The uniformity coefficient helps determine how well the filter media can remove particles of various sizes from water. A lower uniformity coefficient indicates a more uniform particle size distribution, which can lead to effective filtration processes, especially in applications requiring precise particle removal.

In addition, the uniformity coefficient is essential in designing filtration systems, as it impacts the filter's efficiency, flow rates, and the potential for clogging. A well-defined uniformity coefficient allows operators to assess the media's performance under operational conditions, thereby ensuring compliance with water quality standards and optimizing the overall filtration process. This makes the uniformity coefficient a critical factor in selecting the appropriate filter media for different water treatment applications.
