The subject of the invention is a membrane for separation of target stem cells from biological samples, more precisely from a single-cell suspension that was prepared from a biological sample. As a result, sterile target stem cells are obtained in physiological buffer. The membrane of the invention consists of a 3D carrier structure made of at least one layer of biocompatible polymer with specific pore size, as a carrier material, and covalently bound target molecules on its surface and/or in the pores. These target molecules are preferably target antibodies, which recognize characteristic antigens that are bound on the surface of the target stem cells and thus bind the target stem cells to the membrane. Target molecules can be either directly bound to the surface and/or in the pores of the carrier structure or are bound to the surface and/or in the pores of the carrier structure through specific functionalized nanoparticles, which are bound to or embedded into the 3D carrier structure of the membrane. In addition, the present invention includes the membrane production process as well as the process and device for the separation of target stem cells from a biological sample, which includes the above membrane as a constituent part.

A cell retention device includes a structured support with a plurality of circumferentially distributed ribs to retain the active filtering surface of a flexible, porous membrane filter medium. The filter medium surrounds the support in contact with the peaks of the ribs, thereby forming axial voids between the rib peaks. This arrangement imparts sufficient structural support over small regions of the filter medium to facilitate its use in a circular (or other rounded) configuration while providing sufficient channel volume to support high throughput of fluid sparse of cells.

A water purifier includes a water purifier body, a filter bracket provided inside the water purifier body, a pump unit provided inside the water purifier body and including a pump connected to a main water purifying filter installed in the filter bracket, and a vibration transmission-preventing unit which, while the main water purifying filter is installed in the filter bracket, ensures the transmission, to the filter bracket and the water purifier body, of vibrations due to the pressure difference between the pump and the main water purifying filter when water is supplied to the main water purifying filter by means of the pump is reduced by a filter vibration-damping member.

An immersed hollow fiber membrane module according to an embodiment of the present disclosure includes a hollow fiber membrane bundle formed by fixing a plurality of hollow fiber membranes by a potting agent, and a module supporting unit provided at one side of the hollow fiber membrane bundle to support the hollow fiber membrane bundle, the module supporting unit having an air cleaning time delaying portion configured to delay or intermittently maintain an air cleaning time for air introduced therein and discharged out.

A modular filtration platform having at least one manifold head and at least one respective filter cartridge assembly. Each manifold head is connected to one another to establish a water flow in a series or parallel manner. Each filter cartridge assembly is releasably secured from rotation relative to the manifold head by a locking mechanism. An aperture on the filter cartridge assembly annular collar mates with a protruding resilient extension on either the manifold head or support bracket. Alternatively, an aperture on the filter cartridge assembly annular collar and an aperture on the manifold head annular collar mate with a protruding member from a locking ring extending through both apertures. An integrated sensor package may be integrated with the system for true managed water visible/audible indications and Wi-Fi interface to facilitate virtually instantaneous response times for filtration needs.

A method for preparing a membrane stack for electrodialysis as well as a membrane stack according to the method for preparing a membrane stack for electrodialysis and the use of the membrane stack. The membrane stack includes at least two membranes, a cation-exchange membrane and an anion-exchange membrane, in which the at least two membranes include at least one flow channel, an inlet and an outlet wherein the at least two membranes further comprise an edge surrounding the at least one flow channel, the inlet and the outlet.

Provided is an improved filtration module assembly comprising a vessel having a filtration cartridge disposed within it and a header coupled to an end of the vessel, the header including a housing having an open-ended upper end and a lower end, and an end cap including a portion that mates with a complimentary structure defined by the inner all of the open ended upper end of the housing to removable engage with the housing and the end cap may further define a passageway for fluid to flow out of the vessel. The filtration module assembly may enable an improved manifold arrangement used to communicate fluids to and from a filtration system comprising a plurality of such modules and the configurations of the present invention may facilitate improved operation of such filtration systems.

The “sludge dehydrator” equipment is a machine that permits to remove low turbidity water from sludge or watery pastes of industrial or mining origin, with the following objectives: To optimize ore recovery processes such as flotation by means of an increase of the sludge density; To thicken sludge or watery pastes for optimizing the filtering and drying processes, as well as to dispose of mining tailings; To concentrate and dispose of solids in suspension and to recover and recycle clean or clarified water. The “sludge dehydrator” equipment has been designed on the basis of a rectangular tank provided with the necessary infrastructure for containing inside a series of suction plates being connected to a vacuum system, through which the process of solid-liquid separation is carried out and, on the other hand, to contain the cleaning mechanism—the cleaning car—with its motor system made up by pneumatic or hydraulic components required to clean suction plates the filtering medium and to keep them permanently operative. In accordance with the “sludge dehydrator” feeding and the design of the lower or bottom cone of the rectangular tank will benefit to be derived from the industrial and mining operation.

An object of the present invention is to provide a separation membrane module in which an end member is prevented from coming out even at the occurrence of a reverse pressure or the like. The invention relates to a separation membrane module which is equipped with a cylinder-shaped housing and a tubular separation membrane and which takes out a fluid which has permeated the tubular separation membrane. An end pipe is connected to one end portion of the tubular separation membrane; the end pipe is supported by a support plate which is disposed so as to traverse the housing; and an end plug is connected to the other end portion of the tubular separation membrane. The separation membrane module is further equipped with a coming-out preventive member.
