A liquid separation system and related method for retaining floating and non-floating particulates within a storage chamber of a treatment tank. The tank may or may not include a bypass to allow a portion of liquid coming into the tank to bypass the storage chamber. The storage chamber includes an inlet and an outlet. The outlet may be positioned within the storage chamber to cause minimal disruption of the primary and secondary liquid flow patterns within the storage chamber. A circular or rotational flow pattern may be created within the storage chamber and an outlet port of the storage chamber may be centered on an axis of the circular flow pattern.

Apparatus for separating particulate from stormwater

A biosafety cabinet device includes one or more walls forming a housing, a work area contained within the housing, a filter in fluid communication with the work area for filtering fluid passing through and exiting the work area. The filter includes a primary filtration surface through which a majority of fluid being filtered by the filter passes. A filter removal device is configured to couple to the filter. The filter removal device includes a rigid barrier layer and one or more handling mechanisms adjoined with the rigid barrier layer and extending distal to the rigid barrier layer. When the filter removal device is securely coupled to the filter, the rigid barrier layer extends substantially across a non-peripheral portion of the primary filtration surface of the filter and allows passage of fluid from the work area through the primary filtration surface of the filter.

Biosafety cabinet filter removal devices, systems, and methods

A stormwater filter assembly includes a hood and an outlet tube within the hood for draining filtered stormwater. The outlet tube has a solid wall along at least a portion of its height, and an inlet above the solid wall. A second tube is disposed about the outlet tube defining a flow space therebetween for receiving filtered stormwater. The second tube includes a wall that is perforated along at least a portion of its height that overlaps with the solid wall of the outlet tube such that filtered stormwater that enters the flow space must move upward to enter the outlet tube. A filter media is disposed between the hood and the second tube through which stormwater travels during a filtering operation.

Filter assembly, system and method

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.

Stormwater filter assembly

A stormwater filtration system includes a stormwater containment structure including a bottom surface, an inlet that receives stormwater and an outlet through which filtered stormwater exits the stormwater containment structure. A flow structure is at the bottom surface. The flow structure includes a conveyance conduit running along the bottom surface of the stormwater containment structure and in fluid communication with the outlet of the stormwater containment structure. The conveyance conduit includes a port extending through a sidewall of the conveyance conduit. A saddle includes an upper component and a lower component connected to the upper component such that the upper and lower components straddle the conveyance conduit at the port. The upper component includes an opening in communication with the port and the lower component supports the conveyance conduit above the bottom surface.

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.
