|20130175216||PHOSPHOROUS MITIGATION FOR GREEN FILTER BEDS - A stormwater filtration system suitable for treatment of stormwater runoff in a developed environment uses a treatment bay that includes a filtration bed with live plant matter and a plurality of functional layers. The filtration bed may include an adsorption layer or area that contains a phosphorus adsorptive granular media. In accordance with another aspect, the filtration system includes a layer of permeable pavers.||07-11-2013|
|20100038327||THERMALLY TREATED EXPANDED PERLITE - A thermally treated expanded perlite that can be coated or impregnated with at least one active material and the use of the thermally treated expanded perlite as a light-weight filtration media. Methods for forming thermally treated expanded perlite as well as methods for forming thermally treated perlite coated or impregnated with an active material are also disclosed.||02-18-2010|
|20080277327||Stormwater Filter Assembly - A filter assembly for use in filtering stormwater includes a bottom including a boss that includes a rib extending laterally along an inner surface of the boss. The rib includes a locking portion that mates with a corresponding locking portion on a peripheral surface of a connection to an outlet conduit for securing the bottom to the connection thereby inhibiting rotation of the bottom relative to the outlet conduit. A center tube is secured to the bottom using a locking mechanism that inhibits relative movement between the bottom and the center tube. The center tube is in communication with an opening in the bottom and a hood is secured to the center tube. A filter medium is located between the hood and the center tube.||11-13-2008|
|20080277326||Pre-Assembled Flow Control Structure and Related Media Filtration System - A stormwater filtration system includes a stormwater containment structure including a concrete floor and a pre-assembled flow structure embedded in the concrete floor. The pre-assembled flow structure includes an inlet compartment housing, an outlet compartment housing and at least one filter conduit positioned between the inlet compartment housing and the outlet compartment housing and in flow communication with the interior of the outlet compartment housing. At least one bypass conduit extends from the inlet compartment housing to the outlet compartment housing for delivering water from the interior of the inlet compartment housing to the interior of the outlet compartment housing. A plurality of filter units are connected to the filter conduit so that stormwater filtered by the filter units passes into the filter conduit and then to the interior of the outlet compartment housing.||11-13-2008|
