Abstract: A well head cover is disclosed for mounting on a landfill gas discharge pipe. The well head cover includes a polymer molded body, with the body having a neck with an outlet orifice surface sized to accommodate the landfill gas discharge pipe extending through the outlet orifice surface. A stabilizer is disposed within the body that stabilizes the polymer molded body to the landfill gas discharge pipe, and assists in maintaining the landfill gas discharge pipe in a vertically upright orientation.

Abstract: An air stripper apparatus is disclosed which incorporates a plurality of trays that are removably supported within a cabinet. A plurality of downcomers are also fixedly disposed within the cabinet, rather than on the trays. Removing the downcomer from each tray enables a simpler, lighter and easier to clean tray to be constructed.

Abstract: A fluid inlet and distribution system for a volatile organic removal device includes a cabinet having an upper wall and multiple downcomer assemblies positioned within the cabinet accessible through a cabinet access. The multiple downcomer assemblies are divisible into first and second cabinet compartments isolated from each other by a dividing wall. A flow distribution duct assembly connected to the upper wall of the cabinet includes upper, bottom, outward facing and inward facing substantially flat containment walls defining a generally rectangular shaped flow passage. A contaminated fluid inlet is connected to one of the upper, inward facing, or outward facing containment walls. A discharge duct connected to the bottom containment wall is positioned above a receiving chamber operating to equally divide a flow of a contaminated fluid containing a volatile organic compound discharged through the discharge duct equally to the first and second cabinet compartments.

Abstract: 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.

Abstract: A cam-bolt assembly includes a latch handle having a cam portion having first and second cam arms. A hinge pin slides through an aperture created through the cam arms and includes a threaded aperture. A clamp rod has a threaded portion engaged with the threaded aperture and opposed washer engagement flats each having a pin receiving bore aligned perpendicular to the flats. A pivot washer is rotatably connected by a pivot pin received through the pin receiving bore and is rotatable from a first position having the pivot washer coaxially aligned with a clamp rod longitudinal axis to a second position transverse to the first position. The pivot washer rotates from the first to the second position in either a clockwise or counterclockwise direction. The pivot washer is retained in the second position by horizontal displacement in a direction transverse to the clamp rod longitudinal axis after rotation.
