Systems and methods are provided for separating blood into two or more components. A blood separation system includes a blood separation device and a fluid flow circuit configured to be mounted to the blood separation device. The blood separation device includes a centrifugal separator and a spinning membrane separator drive unit incorporated into a common case, which allows for fluid separation by two different methods. Depending on the separation procedure to be carried out, the fluid flow circuit paired with the blood separation device may include only one separation chamber configured to be mounted to the centrifugal separator or spinning membrane separator drive unit or two separation chambers, with one being mounted to the centrifugal separator and the other to the spinning membrane separator drive unit. The system may be used to separate and collect any combination of red blood cells, plasma, and platelets.

A dewatering screen includes a frame upon which is mounted a deck having a plurality of apertures therein, the frame being mounted on a base and being provided with vibration generator for imparting vibration to the deck. A delivery means delivers wet particulate material to be dewatered onto the deck, and there is at least one dividing wall extending across a portion of the deck, the dividing wall(s) separating the deck into a material dewatering region and one or more water drainage regions. The delivery means delivers wet particulate material to be dewatered onto the material dewatering region.

A separator, for separating solids from a liquid, comprises a hydrodynamic separator, a first filtration device, a first backwash device, a second filtration device, and a second backwash device. The first filtration device comprises a first inlet at a first level for receiving at least a first portion of the liquid from the hydrodynamic separator, and a first filter for filtering the first portion of the liquid received via the first inlet. During filtration of the first portion of the liquid, the first portion of the liquid passes through the first filter away from the first inlet and a first portion of solids is retained by the first filter. The first filter is located between the first inlet and the first backwash device. The first backwash device is configured to alternately prevent and allow the passage of the first portion of the liquid through the first backwash device such that, when the passage of the first portion of the liquid through the first backwash device is prevented, the first portion of the liquid that has passed through the first filter passes back through the first filter toward the first inlet so as to remove the first portion of solids from the first filter. The second filtration device comprises a second inlet at a second level higher than the first level for receiving a second portion of the liquid from the hydrodynamic separator, and a second filter for filtering the second portion of the liquid received via the second inlet. During filtration of the second portion of the liquid, the second portion of the liquid passes through the second filter away from the second inlet, and a second portion of solids is retained by the second filter. The second filter is located between the second inlet and the second backwash device. The second backwash device is configured to alternately prevent and allow the passage of the second portion of the liquid through the second backwash device such that, when the passage of the second portion of the liquid through the second backwash device is prevented, the second portion of the liquid that has passed through the second filter passes back through the second filter toward the second inlet so as to remove the second portion of solids from the second filter.

A filter assembly including a filter screen (27) comprising a band (27′) of porous material extending between two axially aligned opposing ends (38, 38′) and defining a cylindrical periphery (29), wherein the ends (38, 38′) are each secured to a dynamic tensioning mechanism (46) that permits the ends (38, 38′) to move bi-directionally relative to one another about the periphery (29) of the filter screen (27).

A flocculation system is provided including a vessel having an open top. The flocculation system also includes a sidewall comprised of a water-impermeable material. The flocculation system further includes a first bottom comprising the water-impermeable material. The flocculation system further includes a second bottom having a floc filter that passes flocs and prevents the passage of a cleaning tool. The flocculation system further includes a floc trap below the second bottom. The floc trap includes a space defined by the sidewall, the first bottom, and the floc filter. In some implementations, the flocculation system includes a flocculant disposed on the sidewall, the floc filter, or the first bottom.

The present disclosure relates to luterion, which is a mitochondrial-like micro-material, and separating and culturing methods for same and, more particularly, to a method for separating luterion by means of a filter having a pore of a particular size, luterion which is separated by means of the method thereof and has unique properties, and a culturing method for proliferation of the luterion.

A method and apparatus for collecting agricultural manure in a confined animal feeding operation includes a separator which receives heavy manure removing particulate from suspension to produce light manure. Heavy manure is collected to a volume of heavy manure sufficient to substantially fill the first tank. Within the first tank, particulate migrates, due to the influence of gravity to form a layer containing manure comprising a lesser density of particulate than is present in the volume of heavy manure. Additional heavy manure buoys the layer such that the upper surface exceeds a height of a weir. The weir is situated in a channel communicating between the first tank and a second tank configured to receive light manure from the separator.

Provided is a non-point pollutant source treatment apparatus. The non-point pollutant source treatment apparatus includes an inlet pipe for allowing initial polluted rain (raw) water to flow therethrough, a settling tank coupled to the inlet pipe and storing raw water flowing from the inlet pipe, a drain part disposed at one side of an inside of the settling tank directly under the inlet pipe, and coupled to a drain pipe so as to discharge raw water contained in the settling tank into the outlet pipe, a purifying member disposed at the other side of the settling tank and including purifying plates with inlet holes, a filtering part coupled to an upper portion of the settling tank and filtering foreign substances from raw water, and a backwashing tank coupled to an upper portion of the filtering part and including a purified water pipe.
