Pumice Water Filtration Media

Pumice Water Filtration MediaPumice Filtration Media is a low-density media typically used in multi-media filters to enhance the capacity of the filter and to remove smaller micron particles. Pumice sits as the top layer in a multi-media filter and is widely used for pre-treatment in desalination and seawater reverse osmosis plants (SWRO).
