Kraken Filter is an efficiently engineered stormwater membrane filter that provides high flow rates and over 170 sq.ft. of surface area. This much filter surface area allows it to operate at a loading rate of only 0.05 gpm per square foot, to ensure maximum performance and minimum maintenance. The Kraken Filter’s low loading rate allows it to keep maintenance needs low and prevent clogging issues often found in other filter systems advertising high loading rates.

High Flow Rates & Maximum Surface Area
Loading Rate of 0.05 gpm/sq.ft., for Minimal Maintenance
Membrane Filter Cartridges can be Easily Removed & Cleaned by Hand
Built-in Pre-treatment Chamber Captures Trash, Sediments, Debris and Hydrocarbons
Filter Cartridge Dries out between Storm Events to Prevent Biofilm Growth which can Cause Clogging and Other Performance Issues
To reduce loading on the membrane cartridge, runoff is initially passed through the pre-treatment chamber to capture trash, hydrocarbons and sediments. Once runoff is pre-treated it is directed to the filter chambers for primary treatment.
During the fill up process a riser tube prevents flow through the membrane cartridge until the water level nears the top of the cartridge. This ensures loading is evenly distributed over the vertical height of the cartridge – maximizing efficiency.
As the water level reaches the top of the membrane cartridges, flow through will begin. The riser tube creates an upward flow path within each cartridge to increase performance. Treated water then passes down the riser tube and collects in the under drain manifold and flows to the discharge chamber.
An optional internal bypass is available with most system configurations. When flows exceed the treatment capacity of the system the water level rises and goes into bypass. High flows are conveyed from the pre-treatment chamber directly to the discharge chamber to prevent scouring of fine sediments captured within the filtration chamber.
The Kraken membrane filter’s ability to accommodate high flow rates while requiring minimal maintenance, makes it beneficial for a wide range of stormwater applications.
