Abstract:
A storm water catch basin hazardous liquid valve that is automatically responsive to the presence of hazardous liquids in storm water run-off, the valve utilizing a hydrophobic barrier member to separate hazardous liquids from water. Collection of a sufficient amount of hazardous liquids across the hydrophobic barrier member initiates a float release member to seal off the catch basin. In the neutral or non-activated status, the storm water run-off enters the catch basin, passes through the valve assembly and out through the storm water conduit system in normal manner. When a hazardous liquid, such as oil, gasoline, chemicals, etc., is present in the storm water run-off above a threshold amount, the valve activates to close off the catch basin such that the storm water run-off is precluded from entering the storm water conduit system.
Abstract:
A catch basin filter having a bag member with a plurality of compartments, the compartments containing heavy metal recovery material, whereby heavy metals in liquid passing through the compartments are filtered from the liquid stream or neutralized.
Abstract:
A subsurface hydrocarbon capture apparatus having a filtration member connected to a mouth frame, wherein the filtration member is composed of a material that is hydrophobic and lipophilic, the apparatus having buoyancy and weight members to maintain the apparatus in a subsurface disposition when pulled by a boat.
Abstract:
A dynamic filter member comprising a mass of lipophilic, hydrophobic fibers and bioremediating microbes, said filter member having a sufficient volume of interstitial areas such that water flow through said filter member is substantially unimpeded.
Abstract:
A methodology, and related systems and structures for accomplishing the methodology, of biological remediation of hazardous or undesirable organic matter, wherein a plurality of carrier members are disposed in a localized retaining member, the carrier members releasing or exposing microorganisms to the undesirable organic matter on a staggered basis over an extended period of time, the microorganisms being capable of biologically remediating the undesirable organic matter by utilizing the organic matter as a food source, thereby converting it into environmentally safe bi-products.
Abstract:
A drain grate filter assembly having a filter sheet member, wedging anchors and mechanical fasteners, whereby the assembly is connected to a drain grate by inserting wedging anchors into the apertures of the grate, placing the filter sheet member atop the grate and inserting fasteners through the filter sheet member and into the wedging anchors.
Abstract:
A methodology, and related systems and structures for accomplishing the methodology, of biological remediation of hazardous or undesirable organic matter, wherein a plurality of carrier members are disposed in a localized retaining member, the carrier members releasing or exposing microorganisms to the undesirable organic matter on a staggered basis over an extended period of time, the microorganisms being capable of biologically remediating the undesirable organic matter by utilizing the organic matter as a food source, thereby converting it into environmentally safe bi-products. Carrier members containing nutrients necessary for the survival of the microorganisms and having release times corresponding to the release times of the microorganisms are also provided to insure that the microorganisms remain viable upon release.
Abstract:
A modular curb inlet filter apparatus having an internal axial tube member on which are disposed at least two disc spacers, which in turn support a cylindrical mesh frame member, which in turn supports a tubular filter fabric. Wedge anchors composed preferably of a compressible polymer foam are provided with anchor bores of sufficient diameter to receive the ends of the cylindrical mesh frame member therein, the anchor bores being disposed near the base of the wedge anchors such that the curb inlet filter inlet apparatus will be seated close to surface of the curb inlet base when positioned within the curb inlet. Preferably the wedge anchors are provided with a base scuff plate made of a durable polymer material to prolong their use life. A short silt flap or skirt depends from the filter fabric, the silt flap extending the approximately the length of the curb inlet filter apparatus to seal any gap beneath the curb inlet filter apparatus and the base of the curb inlet. Connector fitting members are provided such that the axial tubes may be connected end-to-end in modular manner to create longer structures.
Abstract:
A tactile warning pad composed of a polymer material, the pad comprising contact structures on its upper surface and embedded shearable anchor members in the form of a corrugated mesh webbing, wherein the upper portions of the mesh webbing are embedded within the pad and the lower portions of the mesh webbing extend below the pad, such that the pad may be positioned atop an uncured concrete base with the lower portions of the mesh webbing embedded within the concrete, and further such that the anchor members retain the pad on the concrete base once the concrete has hardened, and further such that the pad is removable from the concrete by shearing the anchor members at the interface between the concrete base and the polymer pad using a bladed shearing implement.
Abstract:
An improved spill boom having an elongated tubular main body filled with water, sand or the like through a filling port, and having an elongated base seal member attached beneath the tubular main body. The base seal member is formed of a flexible, relatively soft polymer material such that the underside surface of the base seal member self-conforms to the surface configuration of the ground or other substrate upon which the spill boom is disposed. Short segments at the ends of the base seal member are not connected to the tubular main body, such that a connector sleeve member can be disposed between the base seal member ends and the ends of the tubular main bodies of two adjoining booms, the connector sleeve member receiving the ends of the tubular main bodies in an abutting manner.
