The High Capacity Kraken® Filter

The High Capacity Kraken® Filter

The High Capacity Kraken® Filter is a state-of-the-art stormwater treatment system utilizing advanced membrane filtration, ensuring a high level of removals for total suspended solids (TSS), phosphorus, nutrients, metals, trash, and hydrocarbons.

Why Contech Start a Project

The High-Capacity Kraken® Filter - A Stormwater Filtration Solution

The High-Capacity Kraken® Filter is a state-of-the-art system utilizing advanced membrane filtration, ensuring a high-level of removal for not only TSS, but also metals, trash, nutrients, and hydrocarbons.

At the heart of the Kraken are the filter inserts. A 30” tall filter has over 170 sq ft of surface area, allowing it to treat 17 gpm at a loading rate of only 0.1 gpm/sf.

Available in vault and manhole configurations, the Kraken filter inserts are lightweight, and reusable, providing maximum performance and minimum maintenance.

How the High-Capacity Kraken® Filter  Works

  • During the fill-up process, an integrated interior riser tube prevents flow through the membrane filter until the water level nears the top of the filter. This ensures loading is evenly distributed over the vertical height, maximizing efficiency.
  • Membrane filtration begins when the water level reaches the top of the membrane filters. Treated water then passes down the riser tube, collects in the underdrain 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 pretreatment chamber directly to the discharge chamber to prevent scouring of fine sediments captured within the filtration chamber.

Pretreatment for LID Designs

The Stormwater Management StormFilter, Jellyfish Filter, and the High Capacity Kraken Filter can be easily configured as decentralized pretreatment systems for Low Impact Development Designs. 

Filtration Systems for Water Quality

The Stormwater Management StormFilter, Jellyfish Filter, and the Kraken Filter provide the highest level of treatment and meet the most stringent regulatory requirements. These low maintenance systems combine pretreatment and filtration, and are able to target site-specific pollutants to meet your water quality goals. Our field-proven products have earned hundreds of standalone BMP approvals from regulatory agencies nationwide.

Filtration for Removing Pollutants Prior to Discharge

Media filtration systems - like our StormFilter, Jellyfish Filter, and Kraken Filter are able to remove the most challenging pollutants from stormwater, including total phosphorus, soluble metals, oil, and very fine particles. Available in a variety of configurations (vault, manhole, catch basin, high flow and volume), these systems can be engineered to treat a wide range of flows within your drainage system and capture pollutants prior to discharge off-site.

High Volume Applications

Designing, manufacturing and installing high-volume stormwater detention and treatment systems requires expert engineering, planning, and logistical support to manage costs and keep the project on schedule and under budget. When you need a proven, large scale stormwater management system, “Go Big” with Contech.
