  • Patent number: 6531059
    Abstract: One of the exemplary filter systems described includes a bracket and a filter module that can be suspended from the bracket by a plurality of flexible supports. The bracket can support the filter system beneath the grate of a storm drain without the need for the filter system to be attached to the grate. The grate can be lifted out of the storm drain separately from the filter unit, which allows the filter system to be lifted without the added weight of the grate. When the grate has been lifted out of the way, a suitable fastener structure can be attached to the bracket of the filter system to make the use of mechanical lifting devices more convenient. The bracket can be manufactured to known dimensions, or it can be offered from among a set of brackets that are pre-configured for known storm drain dimensions or as a standard bracket that can be modified to fit the dimensions of a particular storm drain.

A hopper contains a multitude of irregular, macroscopic fragments of a hydrophobic, compliant, oil-absorbent, copolymer material having high surface area. Preferably, the material is formed with a binder in a novel extrusion process. The fragments absorb and retain permanently a high quantity of oil and other chemicals passing through the hopper, while permitting a high water flow-through rate. The fragments are held in place by a removable bottom plate, which allows replacement of the filtering fragments, and an internal basket. Trash and debris are collected in the internal basket. The hopper is configured to be suspended in a storm drain adjacent to a curb inlet on a bracket and can be installed or serviced through a conventional manhole entry. The hopper has a side cutout that permit lateral overflow from one of the modular units to an adjacent one.

  • Patent number: 6106706
    Abstract: A filter apparatus for filtering gross pollution from storm water for fitment to storm water traps located at the entry and exit of storm water, underground and drainage systems. The apparatus includes a gross pollution filter basket located below the entry level of storm water into the trap so as to provide a bypass channel to allow a volume of storm water to pass through the trap. SA storm water bypass means is arranged to restrict entry of incoming storm water and gross pollution into the bypass channel while the combined pressure of storm water and gross pollution inside the trap is such that storm water can still pass through the filter basket.The bypass means which acts like a one-way valve is also arranged to allow storm water and gross pollution to pass into the bypass channel when the combined pressure of storm water and gross pollution inside the trap is such that the storm water is restricted from passing through the filter basket.

  • Patent number: 6027283
    Abstract: An end cap for a drainage system comprises a wall element having substantially the same profile as the cross-section of the end of the trench drain channel section. The wall element is adapted to be coupled to the trench drain channel section to form a terminal end of the channel section. At least one transverse groove is provided in the channel section so that, when the end cap is separated at the groove, the height of the end cap corresponds to the depth of the channel section. Typically, a plurality of transverse grooves are provided at spaced intervals along the vertical height of the wall element which correspond to different possible depths of the channel section. Thus, the end cap may be adapted to fit any one of a number of channel sections, regardless of depth. The end cap may further comprise a pipe coupler integrally molded with the wall element such that the wall element and coupler are substantially continuous.

  • Patent number: 6017166
    Abstract: A catch basin guard and filter for preventing entry into a catch basin and subsequently a storm drain. The preferred embodiment provides a form fitting cover having a grate. The invention is designed for catch basins being installed in construction sites. The invention blocks the inlet of a catch basin, thereby deterring the entry of debris, animals and, most importantly, children. This deterrent increases the completion of construction because the catch basin will need less cleaning and evacuating before coupling to the existing storm drain system. The invention additionally has a mesh filter covering the grate, and a second embodiment employs overflow apertures to provide for the passing of fluids should the filter become clogged.
