摘要： A float operated, top fill, recovery unit floats in a body of contaminated groundwater to recover a layer of liquid hydrocarbons residing on top of the groundwater. The recovery unit has an upper end fitted with a discharge check valve assembly and a lower end that is closed, the discharge valve assembly including a semi-permeable screen which is positioned in and skims the liquid hydrocarbons, and a series of passages and check valves for directing the hydrocarbons via a return line to a holding tank. In an embodiment disclosed, the lower end of the unit is formed in part by an inlet check valve arrangement which has had its check ball removed such that the arrangement does not operate to inhibit flow, and a closure plate is secured to the inlet valve arrangement to prevent external fluid from entering the unit. Sinking of the recovery unit allows hydrocarbons to pass through the screen to fill the interior of the unit so that it can be pumped out of the unit by compressed air and conveyed to the holding tank. The top fill recovery unit is easily modified to a bottom fill underground contaminated water recovery unit by removing the closure plate and replacing the check ball in the inlet valve arrangement, removing the top discharge valve assembly, and connecting the return line directly to the top of the unit.

摘要： A volatile organic compound removal device includes a cabinet having first and second slidable drawers movable between inserted and extended positions. A downcomer tube is downwardly and slidably received in an aperture of the first drawer. A sealing flange extends horizontally outward from a downcomer tube perimeter and extends beyond the aperture when the downcomer tube is received in the aperture. The sealing flange faces an upward facing surface of the first drawer and supports the downcomer tube to the first drawer using only a weight of the downcomer tube applied through the sealing flange to the upward facing surface. A removable seal pot pan is supported on an upward facing surface of the second drawer, which is aligned directly below and receives a lower end of the downcomer tube.

摘要： There is provided a counting apparatus which is designed to be located in any position in series with a fluid flow line. The apparatus has a first magnet in an air chamber of the body of the counter. As the fluid passes through the air chamber, the first magnet is forced down the air chamber by the fluid flow. The magnetic field of the first magnet passes through a magnetic field of a second magnet located in the mechanical counter causing the counter to mechanically change the number. When the fluid flow is stopped, a spring returns the first magnet to its original position again passing by the second magnet in the counter allowing the counter to reset for the counting of the next cycle.

摘要： There is provided an apparatus for obtaining liquid samples from a well which incorporates a vented packer. The packer reduces the amount of groundwater which must be pumped by the pump of the apparatus in order to purge the well by isolating the input of the pump to a reduced volume of groundwater. The region below the packer, which is the region in communication with the pump, is vented to the atmosphere in order to permit the pump to operate at its maximum pumping rate regardless of the recovery rate of the well. The venting of the packer eliminates the condition where the pump is trying to pull a vacuum due to a low recovery rate of the well.

摘要： A liquid pump apparatus is disclosed for pumping groundwater samples, contaminants or other fluids from a well, monitoring site, tank, vessel, or the like. The pump apparatus is applicable in systems including dedicated wellhead assemblies permanently installed at such wells or monitoring sites in order to minimize cross-contamination from site to site. Another application of the pump apparatus for recovery, collection and control system for cleanup of leachate or other liquid material or contaminated groundwater from a landsite is also disclosed. The pump apparatus according to the invention includes check valve means adapted to accommodate vertical, horizontal, non-vertical, or even inverted pump orientations, without requiring a high level of static head in order to function properly.

摘要： A pneumatic sensor/indicator device includes a sensor assembly having a bellows receiving chamber and sensor housing. An elastic bellows is in the bellows receiving chamber. A shaft connects to the bellows so bellows extension/retraction causes shaft axial movement. A magnet connected to the shaft generates a field moving an indicator ring. An indicator dome connects to the sensor body. The indicator ring is in the sensor housing in a non-indicating condition and displaces into the indicator dome providing a visible indicating condition. A flexible sensor tube connected to the sensor/indicator device extends into a well tube having a level sensing tube extending therefrom. A well fluid level rising above a level sensing tube inlet end increases inlet pressure port pressure inducing bellows axial displacement causing indicator device movement toward the indicating condition. The dome and indicating ring are isolated from the well preventing well contents entering and fogging the dome.

摘要： A device for detecting the presence of water in a product-only hydrocarbon pump system particularly used for the removal of subterraneous hydrocarbons from a remediation site through a well. The device comprises a sealed float switch chamber, positioned either upstream or downstream from the hydrocarbon pump, wherein when a threshold amount of water is present in the hydrocarbon product being pumped through the float chamber, a switch is actuated by the float mechanism, electrically signaling an alarm, shutting off the power supply to the pump, or further activating a system controller or log.

摘要： A float operated pneumatic pump has an outer pump body forming an outer chamber and a dip tube forming an inner chamber therein. The inner chamber of the dip tube is in communication with the outer chamber of the pump body through a back flow discharge check valve. An inlet is located at a first end of the outer pump body for permitting liquids to enter both the inner and outer chambers. A discharge housing is located at a second end of the tubes and contains a liquid discharge port in communication with the second end of the dip tube. An air inlet port is located in the discharge housing for permitting pressurized air to enter the second end of the outer pump body. An air exhaust port is provided for permitting air in the outlet chamber to escape to atmosphere when fluid is entering the inner and outer chambers. A float is disposed on the outside of the dip tube within the outer chamber of the pump body. The float provides buoyancy to actuate the pump and provides weight to de-activate the pump. An inlet valve is disposed within the air inlet port for selectively admitting in a discharge mode, and blocking in a refill mode the source of compressed air into the outer chamber of the pump body. An exhaust valve is disposed within the air exhaust port for selectively venting in the refill mode and blocking in the discharge mode the outer chamber to the air discharge port. An actuator linkage, or a lost motion device, is coupled between the float and an off center pivot lever. The off center pivot lever actuates both the inlet and exhaust valves with the off center feature of the pivot lever increasing the force of the buoyant float. The float operated fluid pump further includes first and second attracting magnets, the first magnet being located on the movable end of the off center pivot lever and the second magnet being located within the discharge housing. The first and second magnets come together by movement of the float and operate to keep the pumping system in the discharge mode until the weight of the float separates the magnets and moves the pumping system into the refill mode.

摘要： A floating layer recovery apparatus is disclosed for selectively pumping a liquid floating on groundwater. The apparatus preferably includes a first float which is buoyant in the floating layer attached by a guide to a bottom float which has neutral buoyancy in the groundwater. A middle float is slidably attached to the guide for upward and downward movement between the first and bottom floats. The middle float being an inlet is constructed to have an effective density in the assembly such that it rests at a point where its inlet is near the bottom of the floating layer. Coiled conduits disposed above and below the bottom float carry the floating layer liquid received by the inlet to a pump disposed below. The pump then pumps the floating layer liquid from the conduit to the ground surface. In a preferred embodiment, more precise control over the level of the inlet port is achieved by means of an adjustable inlet port means.
