In one example, a fluid container includes a reservoir that includes a reservoir wall. A cover is configured to engage the reservoir, and the cover includes a spout configured and arranged for fluid communication with the reservoir, and the spout is disposed at one end of the cover. The fluid container also includes a filter cage configured to releasably engage the cover in a location near the spout. When the filter cage is engaged with the cover, and the cover is disposed on the reservoir, a small gap is defined between the front of the spout and the front of the filter cage.

An oil filter may include a housing. The housing may include an inlet, an outlet, and a filter element. The filter element may be located downstream of the inlet and upstream of the outlet. Additionally, the filter element may include a filtering material and a tracer material.

A water cleaner, including a housing and a filter mechanism. Two ends of the housing are provided with a first inlet and a first outlet, respectively. The filter mechanism is arranged in the housing. A first end and/or an outer circumstance of the filter mechanism are/is provided with a second inlet, and a second end is provided with a second outlet. The sewage flows into the housing through the first inlet and flows towards the filter mechanism to be filtered. The obtained clean water flows into the filter mechanism through the second inlet and flows out of the housing through the second outlet and the first outlet in sequence. The first end of the filter mechanism is close to the first inlet, and the second end is close to the first outlet.

A filter assembly that includes one or more features that enhance installation, inspection, and replacement of the filter is provided. In one exemplary aspect, the filter assembly includes a manifold and a filter media assembly that includes a filter media and an end cap attached thereto. The end cap and manifold include features that provide for secure mounting of the filter media assembly with the manifold so as to facilitate inspection, installation, and removal of the filter assembly.

A method of cleaning a regenerative filter having a filter housing having inlet and outlet zones, a fluid path provided between the inlet and outlet zones, and a plurality of filter elements each having an outer surface filter media applied thereto and functioning to filter particulate or contaminants from the fluid path, the method comprising draining all fluids from the filter housing, refilling the filter housing with fluid to an optimum level, and initiating a cleaning sequence of the filter housing with the fluid at the optimum level. The cleaning sequence can comprise agitating the tube sheet, initiating a pump to effectively air scour for a first predetermined amount of time, dwelling for a second predetermined amount of time, and repeating the agitating, initiating, and dwelling until a third predetermined amount of time is complete.

The present disclosure belongs to the technical field of water treatment valve bodies, so as to solve the technical problem that an effective area of a water inlet and outlet hole inside a valve body cannot be simply and effectively reach an effective area of a water inlet and outlet pipe orifice outside the valve body. Based on this, a multifunctional water treatment filter valve is provided, including a valve body, a movable valve plate, a fixed valve plate, and a driving device. The fixed valve plate is fixedly mounted in the valve body; the movable valve plate and the fixed valve plate are in rotatable fit in the valve body; and a side wall of the valve body is provided with a water inlet, a water outlet, and a drainage opening.

The invention relates to preventing microplastics from the entering the environment. In particular the invention is directed to filtering microfibers from the waste water from washing machines as well as waste from other appliances and other sources of effluent with entrained microplastics or other microp-ollutants. A separator is provided for separating microplastics from effluent comprising; a chamber including at least one sieve structure, a shroud that acts as a vortex finder and a baffle coaxial with the shroud and projecting upwards from the lower end of the chamber, wherein the shroud has a circular lower rim and the baffle has a circular upper rim, wherein the radius of the lower rim of the shroud is greater than the radius of the upper rim of the baffle.

An oil filter assembly is disclosed for a machine, such as an internal combustion engine, that has an oil output port and an oil input port. A mounting plate is fixed with an outer enclosure. The mounting plate is further adapted to conduct oil from the machine into a peripheral portion of the outer enclosure, and then returning oil from a central portion of the outer enclosure back to the machine. Oil may pass from the peripheral portion to the central portion through a primary filter having a first porosity. A pressure-actuated valve is fixed fluidly between the portions of the outer enclosure.
