WetlandMEDIA ™


The Modular Wetland System utilizes a proprietary blend of bioretention media that

BioMediaGREEN™ is an amazing material changing the way we think of filtration media. Most systems utilize a granular media that needs to be contained, is heavy in weight and difficult to replace.

outperforms standard sand filters, bioretention systems and standard subsurface flow wetlands. WetlandMEDIA™ provides greater plant growth, moisture retention,

In contrast, BioMediaGREEN comes in lightweight blocks making it inexpensive to ship and simple to replace. This particular media is present in a few capacities within the MWS Linear stormwater system. First, it is utilized in the pre- treatment stage within the Modular Wetland pre-filter cartridges. There is over 25 sq.ft. of surface area per cartridge, and the media itself removes over 80% of TSS and 90% of hydrocarbons. Another ultimate advantage of the pre-filter cartridges are that they prevent pollutants that cause clogging from migrating to the biofiltration chamber. Second, the plant propagation layer of media bedding on the surface of the MWS Linear creates a hearty layer that supports and sustains vegetation. Advantages • Made of various oxides to promote ion exchange of dissolved pollutants • 80% void space allows for double the contact time compared to granular media

evapo-transpiration, and pollutant removal while traditional bioretention media, consisting of compost/organics and sand, has been known to have negative effects, such as leaching nutrients. Advantages • No organics

• Removes phosphorus

• 48% void space

• Greater surface area

• Maximum evapo-transpiration

• High ion exchange capacity

• Light weight

• Excellent physical filtration and hydraulic capacity

• Perlite can also be used
