The present application relates to the technical field of filter assemblies, in particular to an improved filter, including a. filter housing connected to a filter assembly, a connector, an end face seal component, and a filter element. “L”-shaped clamping grooves are formed in an inner wall of the connector. Each of the clamping grooves is provided with a limit bulge. A baffle is installed in the connector. At least two or more clamping blocks matched with the clamping grooves are arranged around an outer wall of the baffle. By arranging the baffle, the replacement and installation of the filter element are facilitated.

An automatic flushing device for a screen filter of a biogas slurry drip irrigation system and a use thereof are provided. The automatic flushing device includes a feeding mechanism, a filter unit, a discharging mechanism and a control mechanism, where the filter unit is provided with a feeding end fixedly threaded to a discharging end of the feeding mechanism and a discharging end fixedly threaded to a feeding end of the discharging mechanism; and the control mechanism is clamped on a pipe of the feeding mechanism. The automatic flushing device enhances the cleaning strength and uniformity of ultrasonic waves to the filter screen. The ultrasonic vibration rod is nested inside the upper filter casing through the externally-threaded hollow cap and a threaded top portion of the upper filter casing, which greatly facilitates the cleaning, replacement and maintenance of the ultrasonic vibration rod.

The present invention provides a depth filter which contains fine particles and coarse particles, and which exhibits excellent filtration precision with respect to a high concentration fluid and/or a high viscosity fluid. This depth filter enables filtration for a long period of time, while maintaining a low filtration pressure.

The present invention is a depth filter which is obtained by winding a fiber sheet into a cylinder, and which comprises a pre-filtration layer and a microfiltration layer; the pre-filtration layer and the microfiltration layer are formed of a fiber sheet; the fiber sheet is composed of a nonwoven fabric or a web; the average fiber diameter of the fiber sheet continuously decreases from the pre-filtration layer toward the microfiltration layer; and the average weight per square meter of the fiber sheet continuously decreases from the pre-filtration layer toward the microfiltration layer.

A fuel filter monitoring method includes receiving pressure signals that are indicative of a pressure drop across at least one fuel filter of a fuel supply system configured to supply fuel to at least one fuel injector of an internal combustion engine and receiving a condition signal indicative of a condition of a fuel supply system, the condition signal being generated by one or more of a geographic location sensor, an altitude sensor, and/or a fuel temperature sensor. The method includes estimating a remaining life of at least one fuel filter of the fuel supply system based on the pressure signal and the condition signal and outputting a notification indicative of the estimated remaining life.

A method for generating a maintenance program for the operation of a maintenance system at a bioreactor, in particular a bioreactor of a vehicle for transporting persons, which method comprises at least the following steps, which are executed by an electronic data processing means associated with the maintenance system: acquiring system characteristics data of the maintenance system; acquiring reactor characteristics data of the bioreactor, the reactor characteristics data being received at least in part from a communication interface of the bioreactor; and generating the maintenance program at least on the basis of the system characteristics data and the reactor characteristics data.

A sanitation device for cleaning a body of water in an immersion pool of a mikvah has a housing, a driving member and a bypass passageway. The housing includes an inlet, an outlet and internal liquid passages that communicate between the inlet and outlet. The driving member is arranged to urge flow of liquid through the internal liquid passages by exerting thrust upon liquid flowing through the driving member, wherein at least part of the liquid flowing through the liquid passages bypasses flowing through the driving member by flowing through the bypass passageway towards the device's outlet.

A sand control screen assembly includes a base pipe having openings through its thickness, and a mesh layer having mesh material sections coupled to safe edges, or connectors, for connecting sections together. The safe edges include areas of thinning to provide flex joints that yield when exposed to high stresses. The mesh layer may be a drainage layer or a filter medium of the sand control screen assembly.

A device for supplying injection water capable of stably supplying the water to a water injection system of a vehicle. The device for supplying injection water includes a storage unit configured to store water, a management unit mounted on the storage unit and configured to detect a state of the water stored in the storage unit and manage the water, a transport unit connected to the storage unit through the management unit and configured to outwardly move the water, and an integrated controller configured to control operations of the management unit and the storage unit.
