Abstract: Apparatus and for the treatment of storm water runoff to remove contaminants that accumulate in the storm water when it flows over paved surfaces in urban areas. The apparatus includes a basket that has an outer surrounding water-permeable wall, and an inner water-permeable wall, spaced from and surrounded by the outer wall. A bed of an absorbent, able to absorb contaminants in the storm water, is disposed in the space between the outer and inner walls, while allowing fluid communication between the walls. An inner drainage space is defined by the inner wall and is in fluid communication with the absorbent. During operation, storm water flows through the outer permeable wall, into the bed where it is treated; and treated water flows from the bed through the inner wall into the inner drainage space. Treated water then flows from the drainage space, in some embodiments under a siphon-effect, into a treated water drainage conduit for disposal. The absorbent may be selected from compost, vermiculite, activated carbon, peat, ion exchangers, clays, and the like, and may be in the form of pellets or particulates. The baskets are of modular construction so that the beds are in containers that may be removed and replaced, with minimal labor. Moreover, the baskets may be backflushed to remove particulates and debris that clog the beds and retard the treatment rate.

Abstract: A pelletized composition and method of using this composition for removing pollutants from storm water runoff. A bed of the pellets has a useful initial permeability to storm water runoff, and retains a significant proportion of this permeability for a period of several years. Preferably, the pellets are dried to a moisture content of less than 25 wt. % so that they are able to withstand a crush force of at least 7 lb., without structural failure. Optionally, the pellets may contain gravel that forms a core of the compost pellet and that assists in causing the compost to agglomerate into a rounded pellet. When immersed in water, the pellets retain the original dry shape and maintain a significant proportion of the crush strength while providing interstitial spaces through which storm water can flow thereby reducing the problem of sedimentation that is encountered in unpelletized beds of compost used in this service.

Abstract: A filter assembly that filters water, particularly stormwater, that includes flow regulating, siphon inducing, and surface cleaning features that allow the filter assembly to operate at the design filtration rate for an extended period of time. During filtration, water flows inward through an annular filter medium into a drain manifold. The rate of flow into the drain manifold is controlled by a float valve assembly. A check valve permits air to escape, but not enter, the filter assembly creating a siphon effect when the rate of flow into the drain manifold is increased. The siphon effect draws water through the entire filtration surface and the entire volume of the filter medium. When the external water level decreases to the level of an array of voids in the filter assembly enclosure, the siphon is interrupted by turbulent air streams entering the filter assembly, agitating the filter surface and dislodging particulate matter.

Abstract: A filter assembly (15) for filtering e.g. stormwater includes flow regulating, siphon inducing, and surface cleaning features that allow the filter assembly to operate at the design filtration rate for an extended period of time. During filtration, water flows inwardly through an annular filter medium (31) into a drainage manifold (19). The rate of flow into the drain manifold is controlled by a float valve assembly (33). A check valve (34) permits air to escape, but not to enter. The filter assembly creates a siphon effect when the rate of flow into the drain manifold is increased. The siphon effect draws water through the entire filtration surface and the entire volume of the filter medium. When the external water level decreases to the level of an array of voids (21) in a hood (20) of the filter assembly, the siphon is interrupted by entering air streams that agitate the filter surface and dislodging particulate matter.
