  • Patent number: 11376353
    Abstract: The present invention relates to a method for regulating supply of substituate in an extracorporeal blood treatment with an extracorporeal blood treatment apparatus comprising a dialyzer divided by a semipermeable membrane into a blood chamber and a dialyzing fluid chamber and a device for supplying substituate. Moreover, the present invention relates to an extracorporeal blood treatment apparatus having a device for regulating supply of substituate. Regulation of supply of substituate in the extracorporeal blood treatment takes place as a function of the rheological loading of the dialyzer. To regulate supply of substituate during extracorporeal blood treatment, rheological loading of the dialyzer is determined from transmembrane pressure on the dialyzer and flow resistance of the dialyzer and substituate rate is increased or reduced according to the loading.

  • Patent number: 11369943
    Abstract: The present invention relates to a method for preparing a simply prepared, safe, nontoxic, and biodegradable modified starch; the present invention further relates to use thereof as an adsorbent in adsorbing heavy metal ions and organic compounds, and belongs to the technical field of modified starch material. Starch is used as raw material and modified with thiourea and tungsten chloride; the starch binds to heavy metal ions through a series of coordination or chelation, and thus produces a heavy metal ion adsorption effect; a starch-based carbon composite is prepared, i.e., a modified starch composite. The simply prepared, environmentally friendly, and recyclable modified starch adsorbent with excellent performance and higher practical value effectively removes He ions and such organic compounds as methylene blue from the wastewater; the modified starch adsorbent is expected to develop into a novel water treatment agent due to low loss rate, biodegradability, and recyclability.

  • Patent number: 11351509
    Abstract: In accordance with an embodiment, a filter membrane is sealed with a sealing material prior to using the filter membrane to filter process fluids. The sealing material is a fluorine-based polymer or a polymer with a cross-linking group. Once the sealing material has been placed in contact with the filter membrane, a cross-linking reaction may be initiated using either physical or chemical processes to cross-link the sealing material and to seal the filter membrane within the sealing material, thereby separating the filter membrane from the process fluids, reducing or eliminating leaching of the filter membrane into the process fluid.
