Bio Clean® Catch Basin Inlet Filter
Advantages
Removing trash and sediment to protect our waterways ...
Our nation has some of the world’s most beautiful beaches and waterways. Unfortunately, trash such as cigarette butts, food packaging, cans and bottles, and plastic waste makes its way into streams, creeks, rivers, and the ocean, as rain events wash them into gutters and storm drains.
Bio Clean Catch Basin Filters provide the first defense against trash and other pollutants entering your stormwater steam by providing 100% trash capture at the source, preventing system clogging and improving downstream water quality.
Bio Clean Catch Basin Inlet Filters offer superior durability and customization ... 1-year warranty
Long-lasting, stainless-steel construction
Designed for a wide range of sizes to fit most curb and grate inlets High-flows bypass prevents scouring of previously captured trash and debris Installed and maintained in minutes
Testing Highlight: California Water Board
100% of Trash
Full Trash Capture
Testing Highlight: Over 1,000 LBS of load capacity
Standard Sediment Filter Testing Highlight: Third Party Testing 85% of TSS & 72% of TP
Kraken® Membrane Filtration
Designed for maximized flow rates while meeting trash full capture requirements by the State of California Water Board.
Our filters provide easy access for maintenance from the surface without having to enter the catch basin. Maintenance service takes about 15 minutes and requires no confined space entry.
Each Bio Clean Catch Basin Inlet Filter is designed to be insertable and the expandable trough system is designed to convey water quality design flows through the filter basket while allowing peak flows to bypass over the trough without resuspending captured pollutants. The modular design of the trough system makes it adaptable to any size* or type of curb inlet catch basin. *Some depth restrictions may apply. Bypass to prevent backflow during the largest storm events.
Bio Clean® Catch Basin Inlet Filter Applications
Bio Clean Catch Basin Inlet Filters have been successfully used on numerous new construction and retrofit projects.
The system’s superior durability and customization make it ideal for a wide range of stormwater applications. Each filter fits within a shallow catch basin, giving them the ability to integrate with versatile curb inlet trough systems.
