A fluid filter apparatus includes a first surrounding sidewall, a co-axial second surrounding sidewall, a co-axial third surrounding sidewall, and a co-axial fourth surrounding sidewall, an outer annulus as between the first and third surrounding sidewalls, and a domed end on the fourth sidewall, wherein a first interior is formed between the second and the fourth sidewalls. Also, a ported head body that includes two pairs of opposing inlet and outlet apertures and inlet and outlet chambers, wherein the body is adjacent to the first and third sidewalls and a filter media disposed within the first sidewall. Operationally, a dirty fluid enters therethrough the inlet aperture to the inlet chamber into the outer annulus, to the first interior, and through the dome and communicates onward therethrough the filter media and outward to the outlet chamber and to the outlet aperture.

A blood processing apparatus including a blood supply unit, a centrifuge, a light irradiation unit, a filtering device, and a blood collection unit, which is characterized in that blood is introduced into the centrifuge and centrifuged, the centrifuged blood is passed through a transparent tube provided in the light irradiation unit while being irradiated with light applied, from the outside of the transparent tube, by a light irradiation device configured to include an infrared lamp with a wavelength of 830?5 nm, a red light-emitting diode (LED) lamp with a wavelength of 635?6 nm, a blue LED lamp with a wavelength of 420?5 nm, a green LED lamp with a wavelength of 530?5 nm, a yellow LED lamp with a wavelength of 585?5 nm, and ultraviolet (UV) lamps, and the blood irradiated with the light is filtered using the filtering device and collected in the blood collection unit.

Systems and methods are provided for collecting a platelet product having a target concentration. First and second target concentrations are first selected. Blood is then separated into red blood cells and platelet-rich plasma, with the platelet-rich plasma then being separated into platelet-poor plasma and platelet concentrate. At least a portion of the platelet concentrate is collected in a container as a platelet product having an actual platelet concentration, attempting to collect platelet concentrate having the first target concentration. After separation of the blood has been completed, at least a portion of the platelet-poor plasma and/or an additive solution is pumped into the container to decrease the concentration of the platelet product from the actual platelet concentration to the second target concentration.

The present invention provides a portable high throughput liquid filter system.

A cyclone separator in a dishwasher includes a first housing, a second housing provided inside the first housing, a first filter piece provided inside the second housing, and a back flow part. A waste collection chamber is provided between the second housing and the first housing. The first filter piece encloses and forms a first filter chamber. A flow passage is provided between the first filter piece and the second housing. The flow passage is in communication with the first filter chamber via filter holes, and the waste collection chamber is in communication with the flow passage. An inlet pipe is in communication with the flow passage. A flow medium enters the cyclone separator via the inlet pipe, and forms a cyclone in the flow passage. An outlet pipe is in communication with the first filter chamber, and the flow medium exits the cyclone separator via the outlet pipe.

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).

Disclosed is a preparation system and a preparation method for high-quality xylitol crystals. The preparation system comprises a blending tank, a heat exchanger, a decolorization tank, an ion exchange system, a microporous filter, a first evaporator, a first crystallization kettle, a first centrifuge, a fluidization drying bed, a xylitol dissolution tank, a second evaporator, a second crystallization kettle, a second centrifuge, a hot air drying tank, and a cold air fluidization bed sequentially connected through pipelines. Liquid outlet of the first centrifuge is connected with first inlet of the blending tank. Liquid outlet of the second centrifuge is connected with first inlet of the xylitol dissolution tank. The blending tank is provided with second inlet for receiving xylitol hydrogenation solution. The xylitol dissolution tank is provided with water inlet for pure water. The material output from a product outlet of the cold air fluidization bed is xylitol crystal product. First prepared xylitol crystals are redissolved and recrystallized to prepare xylitol crystals with higher pH and better flavor.

Used oil passes through a centrifuge tank for particulate separation. The oil then passes through an inlet control valve into an oil passageway. The oil passageway transfers the oil, by way of an oil pump, to a second tank and then through a five micron oil filter, through a one micron oil filter, through a two hundred and twenty nanometer oil filter, and through a one micron filter, under six BARS of pressure. There is an outlet valve which received filtered oil from the one hundred nanometer filter.
