Enhance Nutrient Reduction in BMPs

BandG-logoBold & Gold® Filtration Media is a biosorption activated media (BAM) patented at The University of Central Florida’s Stormwater Management Academy. The media is composed of natural and recycled products. Bold & Gold® Filtration Media is added to stormwater best management practices (BMPs) to reduce nitrogen, phosphorus, total suspended solids (TSS), and pathogens in runoff. Bold & Gold® Filtration Media is used to meet stringent Total Maximum Daily Loads (TMDLs) and Environmental Resource Permit (ERP) requirements. Bold & Gold® Filtration Media can be used in any nutrient reduction modeling software to demonstrate nutrient removal efficiencies. In Florida, BMPTRAINS is available and recognized by the water management districts and Department of Environmental Protection for nutrient reduction credits.

Research Proven Removal Efficiencies:

  • Up to 75% Nitrogen
  • Up to 95% Phosphorus
  • Up to 95% TSS
  • Up to 4 Logs Fecal Coliform

Next Generation Nutrient Management for Florida

Summit-Logo-01The Summit High Performance Upflow Filter System (Summit HPUF) powered by Bold & Gold ECT3 media is a high-performance filtration system designed to remove Total Nitrogen (TN) and Total Phosphorus (TP).


Wetpond Polishing Filter: The most common application of the Summit HPUF in Florida is for polishing whereby it can reduce the size of the wetpond and increase overall treatment effectiveness to achieve nutrient removal goals.

Ultra-Urban Developments: Integrates with Detention, Permeable Pavements, Biofiltration, Bioswales and many other systems.

Non-Infiltrating Areas: When on-site soils are not suitable for infiltration, look to the Summit HPUF to solve the problem.


  • Upflow design reduces clogging and maintenance
  • Sustainable, long service life
  • Made from recycled materials
  • Organic free, no degradation of media
  • Targets TN, TP, bacteria and TSS
  • Non-toxic, safe for the environment
  • No leaching of pollutants, permanently bonds with dissolved nutrients
  • Low Impact Development BMP
