Media

SWIG manufactures nature-based media filtration products that follow best management practices (BMP) and comply with the new Florida Stormwater Rules. Our media is formulated to handle variable flows, remove nutrients, metals, and color, treat bacteria, and capture TSS all at once. Ongoing research also shows strong results for the removal of herbicides, pesticides, PFAS, and other Contaminants of Emerging Concern. Our technical staff can provide design assistance and specify the appropriate media blend.

Media Performance and Longevity

All SWIG media blends are backed by direct monitoring and rigorous performance testing.

We are the only media manufacturer to simulate 20 years of accelerated nutrient loading — confirming expected lifespan before a single system goes in the ground.
Our state-of-the-art research facility continuously optimizes media blends for each specific application, ensuring peak performance from installation through the full life of every system.
Non-toxic, requires no chemical additions, and generates no byproducts — making it safe for the environment and straightforward to permit.
Our systems are vegetated by design, creating ecological settings that support local wildlife habitat and recreational green space.

SWIG’s cradle-to-cradle approach recycles our media at the end of its useful lifetime. Our agricultural-sector contacts reuse spent media from nutrient removal systems as an additive to enrich planting soil mixes.
