  • Publication number: 20060016767
    Abstract: A system and related method for separating floating and nonfloating particulate and entrained, suspended, and/or dissolved contaminants from a fluid. The system includes a tank with a lower chamber spaced from an outlet or upper chamber by a confinement deck. The deck includes one or more sockets for receiving one or more filter units for fluid treatment. In addition, the lower chamber of the tank acts as a pretreatment sump to remove floating and nonfloating particulates, thereby reducing the load on the filter units. The filter units are configured for radial and/or upward flow of the fluid from the lower chamber. The filter units may include one or more filter media through which the fluid pass prior to exiting the tank. The filter units include a removable screening retainer for retaining the filter media and/or to screen relatively large contaminants. The filter unit may be removed for ease of tank maintenance and replacement of filter media.

  • Publication number: 20050145555
    Abstract: A screen apparatus for improved separation of particulates from a fluid stream. The screen is configured and arranged to filter relatively large particulates from the fluid stream as the fluid stream passes from a storage chamber of the tank to a tank outlet. The screen is removably affixed to a diverter, such as a baffle, used to divert a portion or all of the fluid into the storage chamber. The screen is preferably shaped to substantially conform to the shape of the diverter to aid in the smoothing of the fluid flow within the retention section of the tank. The screen may be entirely porous, or it may be non-porous at its leading edge to minimize particulate build-up at the transition from the tank interior wall to the screen. The apparatus may optionally include a second screen to provide additional filtering of floating particulates as the fluid level in the tank exceeds the crown elevation of the inlet.
