A filtration method for filtration of nucleated cells that includes providing a filter containing at least one of a metal and a metal oxide as a major component thereof and having a plurality of through-holes therein, and passing a liquid containing the nucleated cells through the filter. The diameter of an inscribed circle of each of the plurality of through-holes is smaller than the size of the nuclei of the nucleated cells, and the inscribed circle of each of the plurality of through-holes touches all sides defining an opening of the through-hole.

The instant disclosure seeks to provide a container lid that allows a liquid to be filtered, carried, and poured using the same lid. The container filter lid includes a lid body, filter material, and filter cap. The filter cap is demountably coupled the lid body. The filter cap includes a top surface. The filter material is positioned between the filter cap and the lid body. The lid body includes a first port. The filter cap includes a second port. The filter cap includes a filter reservoir. The filter reservoir extends from the filter cap opposite the top surface. The filter material is positioned adjacent to the filter reservoir. The filter reservoir is positioned between the top surface and the filter material. The lid body includes a pour spout. The pour spout is positioned opposite the first port. The container filter lid also includes a filter cap gasket.

A liquid accumulator and a heat exchange system having the liquid accumulator are provided. The liquid accumulator includes a barrel body and a one-way valve, and the one-way valve is disposed in the barrel body. The one-way valve includes a valve seat and a valve plate, the valve seat is provided with a valve port, a side of the valve seat towards the outlet end is provided with the valve plate, the valve port is covered by the valve plate. And a protrusion is located surrounding the valve port and the valve plate is capable of moving towards or away from the valve port, so as to open or close the one-way valve.

A cleaning device and methods for cleaning are provided. In one embodiment, the cleaning device includes a head assembly, a body assembly, and a handle assembly. The cleaning device also includes components that enable the cleaning device to operate in dry cleaning modes and wet cleaning modes. Dry cleaning modes can employ a vacuum assembly, including a motor, tubing, and a fluid recovery tank in order to draw in debris and waste into a fluid recovery tank. Wet cleaning modes can further employ a fluid supply tank, a pump, and tubing in order to supply fluid to a brushroll to aid in a cleaning process.

Systems and methods for managing debris material in a fluid are described. In examples, the system may include a flow line that directs a fluid into an inlet of a barrel, through the barrel to filter at least some material from the fluid, and out of an outlet of the barrel. The system may also include a backflush line coupled to the flow line between an inlet valve and an inlet of the barrel and between an outlet valve and an outlet of the barrel. In examples, the system includes a pump positioned on the backflush line, where in a backflush mode, the inlet and outlet valves close to isolate the barrel, and the pump circulates the fluid through the backflush line and through the barrel in a reverse direction to move fluid and material from the barrel to a screen overflow assembly.

A pod assembly for use in a beverage machine is provided. The pod assembly includes a container and a filter disc that is detachably coupled to the container. The container includes a base, a side wall having a lower rim coupling the side wall to an outer perimeter of the base, and a flange coupled to an upper rim of the side wall and extending radially outward from the upper rim. The filter disc includes a central portion with multiple central openings, a dome-shaped portion with multiple secondary openings, an annular portion extending radially outward from the dome-shaped portion, a foot portion extending vertically from the annular portion in a first direction, and a retention flange extending vertically from the annular portion in a second direction.

A liquid filtration system comprising a syringe pump comprising a gas chamber and a movable plunger, wherein the gas chamber has an aperture at a first end and the plunger forms a seal within the internal walls of the chamber; a liquid chamber having two openings, the openings positioned at opposite ends of the chamber and the first opening connected to the aperture of the gas chamber; a bioreactor in fluidic communication with the second opening of the liquid chamber; a filter arranged to filter liquid passing between the bioreactor and the liquid chamber, the filter comprising a permeate outlet for removing filtered liquid; wherein, in use, the plunger may be moved in a reciprocating motion causing a corresponding movement of gas which drives liquid alternately between the liquid chamber and the bioreactor such that liquid passes through the filter and filtered liquid may be removed via the permeate outlet.
