Hydro-Cartridges Storm Drain Filtration System
The catch basin insert is a funnel inside of a bucket that works full of water. This design allows hydrocarbons to float and to be captured and sediments to remain at the bottom.
In a rainstorm a mix of water, solids and hydrocarbons begins to flow into the filter, this slurry travels down the central funnel where the hydrocarbons tend to float and separate to be captured by the absorbent pad at the surface. Solids, silt, heavy metals and other debris continue to flow with the water to the bottom of the filter, where the flow slows down, they precipitate and remain. Water then rises on both sides of the funnel until spilling over into the drainage structure.
Since the Hydro-Cartridges system works full of water it retains a spill in the central funnel, even without absorbent, where it can be easily recovered. This spill containment capability is exclusive to the Hydro-Cartridges storm drain filtration system, and can be as much as 20 gallons. Capacity is dependent on unit size.
We currently stock a wide assortment of Hydro-Cartridges storm drain filters. Contact us for current availability or custom sizes.
Hydro-Cartridges are comprised of two parts. The central funnel and the bucket. These two parts come together to form the body of the filter.
- Prevents contamination of the aquifer by trapping all kinds of hydrocarbons (oil, grease, gasoline, etc.)
- Traps debris, silt, heavy metals and solids from going into the drainage system, extending the system`s life.
- Spills containment capacity minimizing expensive cleanups.
- Easy installation in new or old inlets.
- Inexpensive, simple maintenance and monitoring.
- Available for different inlet types or structure sizes.
