The present invention discloses a deflector disc of a disc tube membrane module, including a deflector disc body, radial water distribution ribs, an inner support ring and an outer support ring. a first end and a second end of the radial water distribution rib are respectively fixedly connected with an inner edge of the deflector disc body and an outer edge of the inner support ring, an annular boss is arranged on the front side of the inner support ring, a seal ring groove is respectively arranged at corresponding positions of the front side and back side of the inner support ring multiple yielding water collecting grooves are annularly and uniformly distributed on the inner surface of the inner support ring and an inner edge of the outer support ring is fixedly connected with an outer edge of the deflector disc body.

A microfilter, a manufacturing method thereof, and a microfiltration unit for holding the microfilter are provided. The microfilter has: a non-epoxy based microfilm; and a plurality of microholes provided on the surface of the non-epoxy based microfilm and penetrating therethrough via UV laser ablation, wherein the surface of the non-epoxy based microfilm is patterned into predetermined sections for locating isolated targets and quick enumeration.

A deep sludge dewatering method using electroosmosis with filter bags, including (1) placing a filter bag on a slope on which a cathode electrode is arranged; (2) injecting sludge into the filter bag, and after the filter bag is filled with the sludge, closing an inlet of the filter bag; and (3) laying an anode electrode on the filter bag filled with the sludge, and connecting the cathode electrode and the anode electrode to a DC power supply via an electric wire, and carrying out energization for electroosmosis so that water flows down the slope. The present invention can be used for recycling of the sludge produced in underground and tunnel excavation projects, and has the advantages of large processing capacity, simple process, good treatment effect and available resource recycling.

An implantable or wearable kidney enclosure that is cylindrical, ovoid, or otherwise non-angular e.g., not rectangular or cuboid), having a circular or oval hemofilter that provides a blood flow pattern from an internal, central artery source radially outwards. Due to the efficient flow of the circular filter design, the enclosure can be made in a cylindrical low profile shape, resulting in a compact enclosure highly suitable for implantable and wearable dialysis applications.

A method is provided that includes collecting, from a patient, gargled fluid that potentially contains a particulate selected from the group consisting of: a bacterium and a virus; passing the gargled fluid through a filter; and subsequently, testing for the presence of the particulate trapped by the filter. Other embodiments are also described.

Reservoir-based management of volumetric flow rates in fluidic systems is generally described. Inventive systems and methods for liquid-liquid separations and/or liquid-gas separations are also described.

Provided is a technique for easily trapping microbiota in a sample. A microbiota trapping device of the present disclosure includes a first solution tank having a first filter adapted to trap residue in a sample, and a second solution tank having a second filter adapted to trap bacteria in the sample. The second solution tank has a vent above the second filter.

A microorganism recovering method high in recovering efficiency is provided. A microorganism recovering method of recovering microorganisms from a liquid sample includes filtering out microorganisms from the liquid sample through a filtration apparatus, the filtration apparatus including a first end and a second end, the filtration apparatus being configured to receive the liquid sample at the first end and being configured to discharge from the second end filtrate generated through the filtering out microorganisms and recovering the microorganisms filtered out by the filtration apparatus together with a culture medium by feeding the culture medium from the second end to the first end.

A system for further filtering a liquid extract material after an initial extraction process. In an embodiment, the system includes a semi-rigid filter cup that is substantially cylindrical, the filter cup having a top and a bottom, wherein the top is oriented to receive filter media prior to a filtration process, and material to be filtered during the filtration process. The filter cup includes an integrated deformable flange at the top of the filter cup, an integrated top o-ring that is integrated into the top of the integrated deformable flange and an integrated bottom o-ring that is integrated into the bottom of the integrated deformable flange.

The invention concerns a filtration assembly (1) for microbiological testing and a method of using the filtration assembly for that purpose. The filtration assembly (1) comprises a ring-like membrane support (10) holding a filtration membrane (11), a cylindrical reservoir (20) of which opposite axial ends have openings and one axial opening is removably and fluid-tightly attachable to the membrane support (10) to define a sample volume adjacent to the filtration membrane (11) on one axial side of the membrane support (10); and a drain member (30) removably and fluid tightly attachable to the membrane support (10) to define a drain channel space adjacent to the filtration membrane (11) on an opposite axial side of the membrane support (10).
