The tanker truck offloading method includes detecting a tanker truck in at least one of a plurality of offloading stations, energizing a blower having an inlet duct coupled to a tank receiving fluid from the plurality of offloading stations, the blower to draw gasses from the tank when at least one tanker truck is offloading at least one of the plurality of offloading stations, de-energizing the blower when no tanker truck is offloading at any of the plurality of offloading stations, energizing a pump having an inlet coupled to the tank when the tank level is above a predetermined high level, and de-energizing the pump when the tank level is below a predetermined low level.

A fuel storage and supply arrangement serves as a source of fuel to be dispensed via at least one fuel dispenser in a fuel dispensing environment. The arrangement comprises a storage tank for containing a quantity of the fuel. A pump assembly draws the fuel from the storage tank providing the fuel under pressure to a fuel supply line. A fuel conditioning assembly includes a housing having a storage volume, a housing inlet receiving the fuel under pressure created by the pump assembly, a housing outlet through which fuel exits the housing, and a housing port through which fuel can be drawn into the housing. A vacuum source in fluid communication with the housing outlet is operative to selectively apply a vacuum to the outlet of the housing so that liquid can be drawn into the housing via the port. A water intake device is in fluid communication with the housing port. The water intake device has at least one inlet situated adjacent to a bottom of the fuel storage tank.

The invention relates to a retaining apparatus (1) having a filter element (3) in a fluid line (2) which can be flowed through in a flow direction (V) by a fluid (F) comprising a foreign fluid (X), having a volume flow control apparatus (5) by way of which the volume flow (S) through the fluid line (2) can be controlled, having a sensor device (6) by way of which the fraction of foreign fluid (X) in the fluid (F) can be determined, and having a control device (7) by way of which the volume flow (S) can be controlled by way of the volume flow control apparatus (5) in a manner dependent on the fraction of foreign fluid (X) in the fluid (F) as determined by way of the sensor device (6). The invention furthermore relates to a fuel tank filling installation having said retaining apparatus, and to a method for retaining foreign fluid from a fluid.

An environmentally-friendly test port mounting in a conventional gasoline/diesel fuel dispenser cabinet to provide a technician access to the fuel line and perform various tests that enables testing to occur at a highline point in the line system. The technician may access the test port while the line system head pressure s maintained at a point above ground. The test port has a quick connect/disconnect fitting disposed in a collar intermediate a mounting for a filter in a conventional gasoline/diesel fuel dispenser and the filter to provide a technician access to the fuel line and perform various tests. The quick connect/disconnect fitting may also be coupled to a hose for draining fuel under pressure into a safety can to prevent spillage during replacement of the filter. The safety can may be emptied into the fuel tank to conserve the fuel, prevent polluting the environment and as a safety measure.

A method and apparatus are provided for controlling a fuel delivery system to limit acidic corrosion. An exemplary control system includes a controller, at least one monitor, an output, and a remediation system. The monitor of the control system may collect and analyze data indicative of a corrosive environment in the fuel delivery system. The output of the control system may automatically warn an operator of the fueling station of the corrosive environment so that the operator can take preventative or corrective action. The remediation system of the control system may take at least one corrective action to remediate the corrosive environment in the fuel delivery system. One or more sensors may be employed to signal proper operation of the remediation system.

A system and parts of a system that can be used to introduce fluid into a closed circuit. The system includes a valve having an inlet, an outlet, a flush inlet; a spool located in a valve body and coupled to a handle, and the spool can selectively, by the positioning of the handle, direct flow between the inlet, outlet, and flush inlet. The system also includes an uptake conduit comprising a valve connector that is configured to couple with the flush inlet, and a conduit, that is configured to allow fluid to flow therethrough. Additionally, the system has a system attachment having a system connector and a valve connector, and the uptake conduit and the system attachment are coupled to the valve.

A drop-in treatment apparatus and system for PFAS-impacted liquids. The drop-in treatment apparatus and system may comprise one or more cartridges having a plurality openings; one or more mesh containers disposed within the one or more cartridges; one or more tethers; a submersible pump coupled to the cartridges via the tethers; and a power source electrically coupled to the submersible pump. The drop-in treatment apparatus may further comprise a plurality of prescribed masses of sorbent or resin filled within the mesh containers, such that the prescribed masses of sorbent or resin are disposed within the cartridges. The prescribed masses of sorbent or resin may be configured to remove PFAS compounds from a liquid and may be in the range of 0.1-50,000 milligrams per milliliter of liquid volume to be treated. The sorbent may be pyrogenic carbon, granular activated carbon, biochar, zeolite, aluminosilicates, and combinations thereof.
