The Kraken™ Filter

The Kraken™ Filter is a state-of-the-art system utilizing advanced membrane filtration, ensuring a high level of removals for TSS, phosphorus, nutrients, metals, trash, and hydrocarbons. The Kraken membrane filter cartridge provides high flow rates, while the system can operate at a low loading rate to ensure maximum performance, minimum maintenance, and far less clogging.

BMPs Advantages

  • No Granular Media to Replace
  • 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

Applications

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.

System Operation

Pretreatment

Pretreatment captures trash, hydrocarbons, and sediments.

Membrane Filtration

Riser tubes create an upward flow path, so loading is evenly distributed over the vertical height of the cartridge.

Peak Capacity

After water passes through the filter and reaches the top of the membrane cartridges, flow through begins.

Bypass

Bypass prevents scouring of sediments captured within the filtration chamber.

Performance

Removal of TSS (NJCAT PSD) 89%
Removal of Trash 99%
Removal of Phosphorus (Expected - Varies with Particle size) 50%
Removal of Total Metal (Expected - Varies with particle size) 50%
Removal of Total Percentage Hydrocarbons (Expected) 90%

Maintenance & Installation

  • Lowest Life-cycle Cost of Any Media Filter
  • Fast and Simple Maintenance Procedures
  • Easily Cleaned with a Standard Vacuum Truck
  • Reusable Cartridge can be Cleaned with a Standard Garden Hose
  • Small Footprint Reduces Installation and Shipping Costs.
  • No Deep Sump Chamber as Found with Tentacle-type Systems. Reduces Excavation Costs.
