Vermiculite is used in a number of storm water management systems and designs. Vermiculite has some interesting cation exchange capabilities, it has been used when heavy metals may be polluting storm water and need to be removed before the water is discharge into streams or rivers.

 

Vermiculite granules can soak up to over three times its original volume in water it can be a a natural filter media for sediment and dissolved contaminants.

 

Vermiculite is to be added to  Perlite at 10 to 50% depending on desired results.

    • Vermiculite and Perlite both can absorb and adsorb a lot of water and because they can also improve drainage capabilities even when holding water, they both have been used when it is desirable to hold back water and give it time to more naturally drain away or be filtered.
    • And because vermiculite has some interesting cation exchange capabilities, it has been used when heavy metals may be polluting storm water and need to be removed before the water is discharge into streams or rivers. For instance, there have been several designs for large parking lots and highways where the storm water is channeled through vermiculite to collect some of these pollutants.
    • In other landscaping/storm water designs, perlite has been added to the soil in "bio-filters" and special retention ponds to both absorb excess water and increase drainage into the natural aquifer.
    • In still other applications, perlite and vermiculite have been used as filtration media in commercial storm water filtration systems. In these units, the filters and filtration media have to be recharged, cleaned, or replaced from time to time---but still some of the filtration properties of perlite and vermiculite have been used.
