摘要: A device (1) and method for media filtration with a preparation container (2). A chamber (5) containing a dissolvable medium (29) is situated between the container inflow and outflow, and has a filter (22). A mixing arm (6, 7), connected to the inflow, protrudes into the medium in the chamber with at least one mixing nozzle (19, 20), disposed at the free end (17, 18) of the mixing arm for generating a directed jet of solvent. The preparation container has bottom (10) and top (8) parts bracketing the chamber. The filter is a sterile, has on the filtrate side facing the outflow, a circumferential outer edge (23) resting on a circumferential rest edge (37) of the bottom part of the preparation container and is connected fixedly thereto. A sterilised filtrate space (39) is formed between the filtrate side (38) of the filter and the outflow situated in the bottom part.

摘要: An erosion, sediment and pollution control product comprises a geotextile which includes cellulose based threads treated to be hydrophobic and cellulose based filler within the tubular geotextile. The geotextile may be knitted and may include lyocell threads and wherein the lyocell threads are treated to be hydrophobic, and are treated with food grade mineral oil. A method of making a tubular knitted geotextile comprises the steps of: supplying cellulose based threads to a circular knitting machine and knitting a tubular substrate, treating the cellulose based threads with one of mineral oil, beeswax, paraffin, petroleum jelly, lanolin, plant-based oils, and combinations thereof, whereby the threads are rendered hydrophobic.

摘要: A method for creating a functional coating on a substrate in vacuum from a deposited monomer material in absence of oxygen and/or radiation from a radiation source. The substrate may be preliminarily activated with inert gas to form an activated layer thereon. The method may include depositing a fluorine containing monomer having a first CF3:CF2 ratio, and forming, on the substrate, the self-assembled polymer coating that has a second CF3:CF2 ratio, where the first and second CF3:CF2 ratios are equal.

摘要: Filter media comprising fine staple fibers and related components, systems, and methods associated therewith are provided. In some embodiments, a filter media may include a layer (e.g., a wet laid layer) comprising polymeric staple fibers having a relatively small average diameter (e.g., less than or equal to about 1 micron). The polymeric staple fiber layer may be designed to impart desirable properties to the filter media, such as a high particulate efficiency and/or fluid separation efficiency, while having relatively minimal or no adverse effects on one or more properties of the filter media that are important for a given application. The filter media, described herein, may be particularly well-suited for a variety of applications.

摘要: Surface modified filter media, including surface modified filter media having enhanced performance characteristics, are provided. In some embodiments, a filter media may comprise two or more layers designed to enhance fluid separation efficiency. One or more of the layers may have at least a portion of a surface that is modified to alter and/or enhance the wettability of the surface with respect to a particular fluid. In certain embodiments involving a filter media including more than one surface modified layer, at least one surface modified layer may have a greater air permeability and/or mean flow pore size than that of another surface modified layer. Such a configuration of layers may result in the media having enhanced fluid separation properties compared to filter media that do not include such modified layers or configuration of layers, all other factors being equal. The filter media may be well-suited for a variety of applications, including filtering fuel, air, and lube oil.
