  • Publication number: 20220362745
    Abstract: The invention relates to membranes for separation, removal, and/or concentration purposes. The object of the invention is the simple and reliable adsorption of the molecules and to simplify the desorption of target molecules that are adsorbed and chromatographically bonded on membranes, preferably without the addition of substances with a high ion content, such as acids, alkalis or salts. The object of the invention is also to develop a value that can be easily measured, which allows for an indication of the current and/or remaining binding capacity of the membrane during the adsorption process and/or the control thereof. The adsorption takes place on a charged membrane and desorption is achieved using physical, electromagnetic and/or the generation of electrical fields. This is carried out with a thin metal layer being applied to one or both sides of a positively or negatively charged membrane and a voltage is applied for desorption.

  • Patent number: 11247154
    Abstract: Filter capsules for showers and sinks used in surgical settings, clean rooms and other contaminant-sensitive settings having modified outlets for improved splash control. Flat, concave, convex, asymmetric concave and asymmetric convex outlet inserts have pluralities of fluid bores with varying orientations to permit enhanced fluid flow control out of the filter capsules including divergent, convergent and mixed divergent/convergent fluid flows. An inlet with an axis offset at an angle to the longitudinal axis of the filter capsule body permits user control over the fluid flow strike point in a sink or shower stall via rotation of the capsule about the inlet connection point. A recessed outlet improves the prevention of contaminant dispersal by recessing the outlet away from contact points and potential contaminant sources.

  • Publication number: 20210268442
    Abstract: The present invention relates to a method for the at least temporary retention of charged biologically active substances such as endotoxins, viruses, and proteins from liquids, and optional later release for better determination. The object is achieved by a method for the at least temporary separation and/or detection of charged biologically active substances in a liquid by means of electrosorption and/or electrofiltration, comprising the following steps: a. providing a polymer membrane with a flat and porous metal coating at least on a first side of the polymer membrane; b. providing a counterelectrode; c. applying a voltage between the metal coating of the polymer membrane and the counterelectrode; d. bringing the polymer membrane and the counterelectrode into contact with the liquid, with the contacting being performed such that the liquid generates at least one connection between the polymer membrane and the counterelectrode.

  • Publication number: 20150196879
    Abstract: A process for producing a porous metal membrane (pore size 10 nm and 1 um), a metal membrane of this type, the use of the metal membrane and also corresponding filter modules. The Dice is 1-20 microns. The plasma immersion ion implantation process is utilized by bombarding a very thin metal foil with noble gas ions accelerated by means of a first accelerating voltage, in particular from both sides. The ion current is selected so that supersaturation occurs in the metal foil. Pores, in particular under the metal surface, are then formed by bubble segregation after supersaturation. Opening of the pores formed under the metal surface by ion implantation is effected by atomization of the surface by means of bombardment with noble gas ions using a second accelerating voltage which is lower than the first accelerating voltage.

  • Patent number: 6383385
    Abstract: The invention relates to a filter device for the physical elimination of microbes, suspended matter and solids from water, which in a housing has a filter insert made of 200 to 10000 hollow-fiber membranes with a defined pore width between 0.001 and 1.0 &mgr;m and which can be mounted on a water tap with its top side. A disadvantage of previously known filter devices is that deposits will adhere to the fibers. In order to remedy this drawback, the bottom side of the device of the invention features separate outlets for filtered and unfiltered water and at least in the outlet for the unfiltered water a valve is fitted with which this outlet can be closed.
