Stormwater filter assembly

A method of assembling a filter assembly for use in filtering stormwater and installing the filter assembly, the method comprising:

• securing a center tube to a bottom using a locking mechanism inhibiting relative rotational movement between the bottom and the center tube, the center tube being in communication with an opening in the bottom;
• securing a hood to the center tube inhibiting relative movement between the center tube and the hood;
• providing a filter media between the hood and the center tube;
• and
• applying a rotational force to the assembly which causes the center tube and bottom to rotate during installation.

A stormwater treatment system for use in filtering stormwater, comprising:

• an outlet conduit connection that connects to a filter conduit for use in delivering filtered stormwater toward an outlet of the stormwater treatment system, the outlet conduit connection comprising a locking portion on an outer peripheral surface of the outlet conduit connection;
• and
• a filter assembly comprising
• a bottom including a boss that includes a rib extending laterally along an inner surface of the boss, the rib including a locking portion that mates with the locking portion on the peripheral surface of the outlet conduit connection for securing the bottom to the outlet conduit connection thereby inhibiting rotation of the bottom relative to the outlet conduit connection;
• a center tube secured to the bottom using a locking mechanism that inhibits relative movement between the bottom and the center tube, the center tube being in communication with an opening in the bottom and the outlet conduit connection;
• a hood secured to the center tube;
• and
• a filter media between the hood and the center tube.

A filter assembly for use in filtering stormwater, comprising:

• a housing structure;
• a drainage space within the housing structure;
• and
• a filter medium between the drainage space and housing structure;
• wherein the housing structure includes a lower portion with a mount opening for mating with an outlet conduit connection, the mount opening including a pair of circumferentially extending and diametrically opposed ribs extending radially inwardly;
• wherein each rib includes a locking tab at one end thereof, the locking tab formed by a raised protrusion of the upper surface of the rib.
