Abstract: A storm water treatment system accomplishes low impact development compliant treatment of storm water with filtrate discharged to an underground infiltration structure. The system has an automatic high-flow bypass under gravity flow, even on flat sites, plus automatic standing water drain-down for mosquito control and de-watering of collected solids. This system incorporates unique distributional piping schemes enabling periodic removal of suspended solids from otherwise inaccessible structures.

Abstract: A watershed runoff treatment device is adapted to be used to convert a single-stage drain inlet vault (catch basin) into a two-stage clarifier in which treatment can be accomplished before discharging the water to further on-site treatment or detention or to storm drain. It includes a flow control box member to be mounted on the interior of the vault covering the discharge pipe(s) so that substantially all water runoff entering the vault must flow therethrough prior to exiting the vault. Floating, disposable hydrocarbon collection pads are deployed inside an open mesh container removably attached and covering the upstream face of the flow control box, as well as below the horizontal filter array described next.

Abstract: Methods, systems, drain vaults, and tools are employed to treat storm water runoff from a watershed. The methods and system may include multiple drain vaults that function to receive and allow quiescence of the water so that laminate flow may be achieved between adjacent vaults. The drain vaults may be made of stacked together vault sections held in compression, and screens and arrays of tube elements are with different drain vaults. There may be combined systems where in an upstream system flow is uncontrolled during a rainstorm and some of the rainfall water is diverted to a retention structure and then in a control flow rate is transferred to a downstream treatment system that may use tube elements. A tool is used to clean the tube elements.

Abstract: A drain inlet vault comprises a plurality of pre-cast concrete vault sections stacked one upon the other to form the vault. Each vault section has essentially the same cross-sectional configuration and at least one perimeter edge that upon stacking the vault sections one on top of the other the perimeter edges of adjacent vault sections engage. A sealant material along the perimeter edges forms a seal as the weight of an upper section bears against a lower section. At least one support element for water treatment equipment, or a component thereof, is mounted between the perimeter edges, and this support element has a portion extending into an interior of the vault for holding the water treatment equipment, or component thereof.

Abstract: A watershed runoff drainage device is adapted to be used with a drain inlet vault for a storm drain. It includes a funnel member to be inserted into an inlet of the vault for directing substantially all water runoff entering the vault to flow there through prior to entering the vault. A floating hydrocarbon collector is positioned inside or outside the funnel member, and deflectors and other means within the vault inhibit the growth of mosquito larvae and the like within the vault and inhibit any mosquitoes within the vault from escaping the vault.

Abstract: A portable translation device includes a microphone connected to an amplification circuit. A voice recognition module receives input from the amplification circuit and recognizes speech in a plurality of languages from multiple speakers. The voice recognition module converts received speech into printable text. A translation module converts the printable text in a first received language to a second chosen language as printable text. A speaker or headphones are connected to the amplification circuit. An output language selection module identifies a language for voice synthesis. A voice synthesis module converts the printable text generated by the translation module into an electronic signal. The signal is input to the amplification circuit and generates audible speech through either the speaker or headphones. A display screen will display the printable text. A voice learning module assists in voice recognition. An auxiliary input device, such as a keyboard also connects to the portable translation device.

Abstract: Disclosed is a magnetic conditioning device and method of using such device including a container having an inlet and an outlet and a row of magnets disposed within the container between the inlet and the outlet. The magnets are aligned so that the adjacent ends of magnets will have the same polarity. Disposed between these adjacent ends are a pair of concentrator plates. This creates an alternating magnetic field of varying intensity which surrounds the magnets. The device includes means for directing the fluid through this magnetic field, preferably making several passes through this field before exiting the container. Preferably, both ends of the array of magnets are of a southern polarity.

Abstract: Disclosed is a device for treating a fluid to remove particles from the fluid and condition it so that scale is not formed on the piping or other structure carrying the fluid. A magnetic conditioning assembly and filter are disposed in a circulating system with the filter being upstream of the magnetic conditioner so that iron particulates are removed prior to accumulating on the surface of the conditioner. These iron particles are thus prevented from interfering with the function of the conditioner. The conditioner treats the water so that scale formation is reduced or eliminated and also prevents or reduces the formation of scale upon the filter element.
