Abstract: Corrugated screen filters and related method of fabrication whereby an available filter surface is increased so as to allow an increase a flow capacity of the corrugated screen filter. The corrugated screen filter can comprise a plurality of rods forming a series of alternate and angular ridges and grooves on a surface of the filter screen. The filter screen can be configured to have longitudinal corrugations only on an exterior surface of the filter screen or alternatively, the filter screen can be configured to have longitudinal corrugations only on an interior surface of the filter screen. The alternate angular ridges and grooves can form corrugations in a variety of configurations including, but not limited to, a sinusoidal wave structure, a triangular wave structure, a rectangular wave structure, a trapezoidal wave structure, or the like.

Abstract: Provided is a biological fluid-treating filter for treating a biological fluid containing erythrocytes, which has a matrix and a polymer retained by the matrix, the polymer having a zwitterion-containing functional group and a basic nitrogen-containing functional group. By using the filter in which the polymer has the zwitterion-containing functional group and the basic nitrogen-containing functional group, it is possible to treat the biological fluid containing erythrocytes without adversely affecting the erythrocytes.

Abstract: A disposable filter cup and stem assembly with a filter disc or membrane secured between the cup and the stem. A frangible filter cup disengagement strip is formed on the filter cup about an end adjacent the stem. The filter disc or membrane is secured in the assembly in close proximity to the disengagement strip. Force applied to the disengagement strip separates the filter cup from the stem to expose the top, upstream surface of the filter disc or membrane and to permit removal of the filter disc from the assembly in an intact, substantially horizontal position. A disposable filter capsule assembly formed with a frangible filter capsule disengagement strip encloses a filter disc or membrane and permits separation of the capsule into two sections so as to expose an upstream surface of the filter disc or membrane and to permit removal of the filter disc or membrane in an intact condition after fluid processing.

Abstract: In a multi-sensor device for a medical apparatus at least one first sensor unit and at least one second sensor unit are arranged at a fluid-guiding line connection along which the sensor units detect at least one variable from a flowing fluid in predetermined proximity to each other in such manner that predetermined signal portions occur and are detectable practically simultaneously in outputs of each of the first and second sensor units. In a method for defining a proximity in said multi-sensor device, positions of the individual sensors are varied in the multi-sensor device and the occurrence of predetermined signal portions is detected in at least two signals detected by the individual sensors, and those positions at which the predetermined signal portions occur practically simultaneously are defined as positions of the proximity.

Abstract: In one example, a filter core includes a body with a generally cylindrical shape and a substantially hollow interior. The body includes a first annular wall disposed proximate a first end of the body, and a second annular wall disposed proximate a second end of the body such that the second annular wall is axially spaced apart from the first annular wall, and the second annular wall and the first annular wall extend toward each other.

Abstract: A system for treating a polar liquid includes a signal generator for providing an alternating electrical current, and a transducer electrically coupled to the signal generator. The transducer includes a solenoidal coil and two ferromagnetic end pieces at the ends of the coil and transverse thereto. In operation, the transducer is at least partially immersed in a polar liquid and, when energized with the current provides a magnetic field into the liquid, the field may change a property of the liquid, e.g. an interfacial mass transfer rate. This can be used in many different industrial applications.

The end cap may include a flange that compresses a gasket member between the end cap and the seat ring to form a fluid tight seal therebetween. The end cap may include cam locking grooves that may each receive insertion of a protrusion of the seat ring, and which are structured for at least rotational displacement about the received protrusion as the end cap is rotated between locked and unlocked positions relative to the seat ring. The end cap may also include an opening that accommodates the passage of a fluid to a filter element.

Abstract: A method or process for treating wastewater containing high organics, silica, boron, hardness, and suspended and dissolved solids. The method includes degasifying the wastewater for the removal of dissolved gases and thereafter chemically softening the wastewater. After the chemical softening step, the wastewater is directed through a media filter or membrane which removes additional solids and precipitants. Thereafter the wastewater is directed through a sodium ion exchange that further softens the wastewater. The effluent from the ion exchange is directed through a cartridge filter and the effluent from the cartridge filter is directed through one or more reverse osmosis units. At a selected phase of the process, prior to the wastewater reaching the reverse osmosis unit or units, the pH of the wastewater is raised and maintained such that the pH of the wastewater reaching a reverse osmosis unit is at a pH greater than 10.5.

Abstract: A Spin-on filter assembly that can be used with both suction-side and pressure-side filtration systems is described. The filter assembly screws onto a filter mounting head. The filter mounting head is part of a filtration system that provides fluid to be filtered to the filter assembly. The filter assembly filters the fluid to be filtered through a filter media contained within the filter assembly and provides the filtered fluid back to the filter mounting head. The filter assembly includes an upper seal that seals the clean side of the filter media from the dirty side of the filter media when the filter assembly is connected to the filter mounting head in an installed position. The upper seal includes a sealing ridge that has an elongated shape and is flexible such that the filter assembly can be used on both pressure-side and suction side applications in filtration systems.
