Abstract: A rapid one-pass liquid filtration system efficiently concentrates biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream. Suspended biological particles include such materials as proteins/toxins, viruses, DNA, and/or bacteria in the size range of approximately 0.001 micron to 20 microns diameter. Concentration of these particles is advantageous for detection of target particles in a dilute suspension, because concentrating them into a small volume makes them easier to detect. Additional concentration stages may be added in “cascade” fashion, in order to concentrate particles below the size cut of each preceding stage remaining in the separated fluid in a concentrated sample suspension. This process can also be used to create a “band-pass” concentration for concentration of a particular target size particle within a narrow range.

Abstract: A filtration efficiency, which is similar to the filtration efficiency obtained when a plurality of filters are provided, can be obtained by one filter, and decrease in throughput can be prevented. Based on a control signal from a control unit 101, a resist liquid L is sucked into a pump 70 through a filter. A part of the resist liquid sucked in the pump is discharged from a discharge nozzle 7. The remaining resist liquid is returned to a supply conduit 51b on a primary side of the filter. A process is synthesized by adding a replenishment amount equal to the discharge amount to the return amount. The discharge of the synthesized process liquid and the filtration thereof by the filter are performed the number of times corresponding to a rate between the discharge amount and the return amount.

Abstract: A cutting fluid filtration device attached to a machine tool has the function of backwashing a filter for filtering impurities in a cutting fluid when the filter is clogged. Whether or not the filter is clogged is determined by integrating the time during which the liquid level of the cutting fluid in a clean fluid tank falls below a lower-limit position by means of a sensor configured to detect the height of the liquid level of the cutting fluid. When a preset reference value is exceeded by the resulting integrated value, it is determined that the filter is clogged.

Abstract: A coolant for a machine is filtered by passing some of the coolant into a discharge tube having an opening, the discharge tube supporting a filter bag. Coolant flowing into the discharge tube flows out of the tube through the opening, and then through the bag, and the filtered fluid is recirculated. An end piece, pivotably mounted to the discharge tube, prevents the bag from falling off while in operation, but can be pivoted to a position which facilitates insertion and removal of the bag. When filled, the bag can therefore easily be removed and replaced with a new bag. The invention greatly simplifies the process of filtering a coolant fluid.

Abstract: An energy efficient desalination process that does not produce waste products involves the extraction of water from a first solution, such as seawater, by using a second concentrated solution to draw the water from the first solution across a semi-permeable membrane. By manipulating the equilibrium of the soluble and insoluble species of solute within the second solution in favor of the soluble species of the solute, a saturated second solution can be used to generate osmotic pressure on the first solution. Also, by adjusting the equilibrium in favor of the less soluble species after the water has been drawn from the first solution, a portion of the solute can easily be precipitated out. Heating the second solution decomposes the solute into its constituent gases. The constituent gases and precipitated solute may be recycled through the process to affect the changes in equilibrium and eliminate waste products.

Abstract: A chemical liquid supply device has a pump provided with a pump chamber which is expanded and contracted by an elastically deformable bellows, and chemical liquid in a chemical liquid container flows into the pump chamber through a suction channel. The chemical liquid in the pump chamber is discharged through a discharge channel to a discharge nozzle.
