A biocompatible and hemocompatible material and filter which is suitable for blood filtration applications. Biocompatibility and hemocompatibility is achieved through a modification of an existing ceramic substrate, in which a pyrolytic carbon layer is coated onto the filter.

Disclosed herein is a method for removing heavy metals from biomass, performed by contacting the biomass with an acid, thereby producing an acidic suspension, solution, paste or a mixture thereof, followed by separating the heavy metals from said biomass, thereby removing the heavy metals from the biomass.

An extracorporeal blood treatment machine for carrying out a blood treatment including a machine front on which a hollow fiber filter module is arranged in a horizontal position, which hollow fiber filter module includes a cylindrical housing, a blood chamber having a blood inlet nozzle and a blood outlet nozzle and a solution chamber having a solution inlet nozzle extending transversely to the longitudinal direction of the hollow fiber filter module and a solution outlet nozzle extending transversely to the longitudinal direction of the hollow fiber filter module, the solution chamber being semi-permeably communicated at least in portions with the blood chamber, wherein a height potential is present in the horizontal position between the solution inlet nozzle and the solution outlet nozzle so that drainage of solution is enabled via one of the solution nozzles and evacuation of air bubbles is enabled via an other of the solution nozzles.

An apparatus and method for replenishing urease in a sorbent cartridge for use in sorbent dialysis. The system is configured to allow insertion of a urease pouch, injection of a urease solution, or addition of a urease cartridge, into a dialysis cabinet containing a dialysis flow loop. The urease can be dissolved and the resulting urease solution added to the sorbent cartridge in the flow loop to replenish the urease within the sorbent cartridge. The sorbent cartridge can also comprise other, rechargeable, sorbent materials for removing toxins other than urea from spent dialysate.

The present disclosure relates to an artificial, extracorporeal system for supporting the function of the liver of a patient suffering from liver failure, which is characterized in that it comprises a first high-flux or high cut-off hollow fiber membrane dialyzer which is perfused on the lumen side with the patient's blood and wherein a buffered aqueous solution comprising human serum albumin is passed in a continuous flow through the filtrate space of said first dialyzer, a second hollow fiber membrane dialyzer which removes water-soluble substances from the dialysate of said first dialyzer, and a third, integrated hollow fiber membrane dialyzer which is perfused with the retentate of second hemodialyzer and which allows the passage of certain amounts of albumin over the membrane wall into the filtrate space which is populated with adsorbent material. The system can be used for the treatment of acute liver failure and acute-on-chronic liver failure.

A dialyzer and a fabricating method thereof are provided. The dialyzer includes a housing, a hydrophilic layer, a fixing layer, a plurality of hollow fiber membranes, and two end caps. The housing has a first opening and a second opening, and is provided with a dialysate inlet and a dialysate outlet, wherein an entire peripheral surface of the housing located between the first opening and the dialysate inlet is a first portion, and an entire peripheral surface of the housing located between the second opening and the dialysate outlet is a second portion. The hydrophilic layer is disposed on the inner wall of the first portion and the second portion, wherein the hydrophilic layer and the housing are different materials. The fixing layer is disposed on the hydrophilic layer and fixes the hollow fiber membranes to the inner wall of the housing.

An end cap of a dialyzer and a fabricating method thereof, and a dialyzer are provided. The end cap includes a main body and a sealing element. The main body has a blood port. The sealing element is integrally connected on an inner wall of the main body.

The present invention relates to a composition comprising at least one aromatic polymer and at least one fluorinated polymer, articles made from such compositions and uses thereof.

A first blood processing member 5U and a second blood processing member 5D are arranged in a first housing 2/U and a second housing 2/D, respectively. The first blood processing member 5U and the second blood processing member 5D are arranged in such a manner that inside filtration sections 5FI/U and 5FI/D face each other. A first blood chamber 2.1 is formed between the inside filtration sections 5FI/U and 5FI/D, and a second blood chamber 2.2 is formed between the inner periphery of the first housing 2/U and an outside filtration section 5FO/U and between the inner periphery of the second housing 2/D and an outside filtration section 5FO/D. A blood inlet port 7I communicates with the first blood chamber 2.1 (a blood inflow chamber 2IR), and a blood discharge port 7O communicates with the second blood chamber 2.2 (a blood outflow chambers 20R/U and 20R/D).

A method of measuring concentration of dissolved organic nitrogen in sewage. The method includes: filtering a sewage sample using a filter membrane; measuring the concentrations of total dissolved nitrogen (TDN), ammonia nitrogen (NH.sub.4.sup.+), and nitric nitrogen (NO.sub.3.sup.) in the sewage sample, respectively designated as C.sub.TDN(I), C.sub.NH4.sup.+.sub.(I) and C.sub.NO3.sup..sub.(I); calculating the ratios of (C.sub.NH4.sup.+.sub.(I)+C.sub.NO3.sup..sub.(I))/C.sub.TDN(I) and C.sub.NO3.sup..sub.(I)/C.sub.NH4.sup.+.sub.(I), and according to the ratios, calculating the concentration of dissolved organic nitrogen (DON) in the sewage sample.
