摘要： In some embodiments, a system for pre-wetting a filter includes a filter, a piping system, a first gas, a second gas, a first buffer tank, and a second buffer tank. The first gas drives the solvent to clean the filter. The two buffer tanks store the solvent discharged from the filter. The second gas selectively drives the solvent in the first buffer tank to return to the filter and then to be discharged into the second buffer tank. Alternatively, the second gas selectively drives the solvent in the second buffer tank to return to the filter and then to be discharged into the first buffer tank.

摘要： A removable filter cartridge includes a filter housing containing a filter and a sealing valve coupled to an open end of the filter housing. The sealing valve configured to removably couple the removable filter cartridge to a filter head. An open position allows fluid to flow into and out of the internal volume of the filter housing. A closed position seals the filter housing. A method for retrofitting a filter housing includes removing the filter housing from a filter head, coupling a sealing valve to the removable filter to form a removable filter cartridge, and coupling the removable filter cartridge to the filter head.

摘要： A filter device has a filter housing (1) having a fluid inlet (8) for unfiltered matter and having a fluid outlet (9) for filtrate, and has at least one one-piece or multi-part filter insert (15, 17) held in the filter housing (1). Filter insert (15, 17) can be cleaned using a backwash device (25) having at least one backwash element (31) in counter flow to the direction of filtration. The backwash element can be moved along the inside of the relevant filter insert (15, 17) by a fluid-conveying drive shaft (29) of a rotary drive (69, 71). The individual backwash element (31) has, at the end adjacent to this inside, at least one gap-shaped passage opening, which extends in parallel to the axis of rotation of the drive shaft (29) and which opens into a flow chamber connected to the drive shaft (29) in a fluid-conveying manner. At least one further backwash device (27) has a further backwash element (31). The fluid-conveying drive shaft (29) is divided into chambers (73, 75) separated from each other. One backwash element (31) of one backwash device (25) is connected to one of the chambers (73, 75). The other backwash element (31) of the other backwash device (27) is connected to another chamber (73, 75).

摘要： According to one aspect of the disclosure, a bulk material handling method includes receiving bulk material on a first level of a system at receiving stations equipped with dust control filtration equipment, pneumatically conveying the bulk material up to a third level into bulk material storage hoppers, storing the bulk material, dispensing the stored bulk material to a bulk material transporter on the first level, including dosing the stored bulk material to an interior of a bulk material dosing hopper to create a bulk material dose, docking the dosing hopper with the transporter via a docking apparatus, and releasing the dose into the interior of the transporter, through a reduced pressure region in an internal volume of the docking apparatus. Other disclosed aspects include a related system, subsystems, and apparatuses.

摘要： A filter for use in filtering a fluid slurry that includes particles of varying size, such as pool water including debris, is provided. The filter is in electrical communication with a sensor and includes a housing having an inlet to receive the fluid slurry, an outlet, and an internal chamber. An actuator can be coupled to the filter media to move at least a portion of the filter media to vary a dimension of the pores. The filter also includes a controller connected to the actuator that is capable of receiving a signal from the sensor and controls the actuator to change the dimension of the pores based on the signal.

摘要： A method including the steps of moving fluid through an inlet into a vessel, the vessel being at atmospheric pressure and having at least one side wall and a bottom wall forming an internal chamber within the vessel. The method further includes moving the fluid into and through a filtration unit utilizing a downstream pump, the filtration unit creating a flux of less than or equal to about 0.05 gallons per minute per square foot (GPM/ft2), and moving the fluid processed by the filtration unit to an outlet and out of the vessel.
