Kraken® Filter - A Stormwater Filtration Solution
挪威海怪®ut过滤器是一种先进的系统ilizing 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 30.75” tall filter has over 170 sq ft of surface area, allowing it to treat 8 gpm at a loading rate of only 0.05 gpm/sf.
Available in vault and manhole configurations, the Kraken filter inserts are lightweight, and reusable, providing maximum performance and minimum maintenance.
How the Kraken® Filter Works
- To reduce loading on the membrane filter, runoff is initially passed through the pretreatment chamber to capture trash, hydrocarbons, and sediments.Once runoff is pretreated, it is directed to the filter chamber for primary treatment.
- 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.
- 一个可选的国际米兰nal 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.
