Analysis filter media

Filter media that have been used for many years in filter basins or filtration machines gradually become dirty. In order to understand the condition of the filter media in use, we recommend testing and analyzing the filter media sample by conducting filter survey work. The sampled filter media will be inspected and analyzed in accordance with JWWA A103-1988. The current status of the filter media can be used as a guide for Filter Rehabilitation Work or Filter Replacement Work. In addition, it can be used as reference data for water quality management.
