The UltraTech 9397 Drain Guard Heavy Metal Removal Model is a catch basin insert engineered to capture heavy metals, hydrocarbons, sediment, and other contaminants from stormwater runoff before they enter the drainage system. Quilted filtration chambers contain a custom blend of heavy metal removal media, while an impermeable PVC skirt directs all incoming water through the treatment media. Designed for installation beneath storm drain grates, it supports stormwater pollution prevention programs and regulatory compliance initiatives.
- Heavy Metal Removal Media – Quilted sections throughout the insert contain a custom blend of filtration media designed to capture dissolved and particulate heavy metals from stormwater runoff
- Controlled Water Flow Path – An impermeable PVC skirt funnels all incoming water through the lower filtration zone, ensuring contact with the treatment media before discharge
- Multi-Contaminant Filtration – Removes heavy metals, hydrocarbons, sediment, and other organic pollutants from stormwater and industrial runoff streams
- High Flow Capacity – Supports stormwater flow rates up to 275 GPM while maintaining filtration performance and debris capture
- Regulatory Compliance Support – Helps facilities comply with NPDES 40 CFR 122.26, SWPPP, and TMDL stormwater management requirements when used as a Best Management Practice (BMP)
