During the past few years, a number of different filter media have been used for stormwater filtration. Media such as sand, peat, and compost have been used successfully. Recent uses of perlite, zeolite, carbon, and other “exotic” media have expanded the choices for targeting specific pollutants. Here are some questions you should ask when selecting the right media for your application...

In this video, Vaikko Allen, Regional Regulatory Manager for CONTECH, explains three approaches to stormwater treatment.

The primary credit applicable for the Stormwater Management StormFilter^® is Credit 6.2, Stormwater Design - Quality Control, under the Sustainable Sites category. There is one credit point allowable under this category for qualifying BMPs.

This patented technology is employed by the Stormwater Management StormFilter in order to prevent surface blinding, ensure use of all media, and prolong cartridge life. In principal, the system siphons stormwater runoff through its cartridge.

There are many aspects of stormwater filtration. Here, we discuss media surface area, surface vs. bed filtration, media hydraulic conductivity and flow control, performance data and longevity.  And how it can help you choose the right stormwater filter system.

Filtering stormwater is an effective way to remove the most challenging pollutants from urban runoff - including fine solids, soluble heavy metals, and total nutrients. Though the physics of filtration are the same, there are many variables to consider when designing a stormwater filtration system. It’s important when designing a filter treatment system to consider a balanced approach that incorporates performance, hydraulics, longevity and life cycle costs.
