Pressure drop in Leopold blocks

Description

The IMS-200 media retainer is designed as a replacement for the filter bed support layer and is fixed to the bottom blocks of Leopold filters in water treatment plants. Made of high-strength injection molded plastic, it is designed as an improvement over gravel and porous plate supports.
