    摘要: Apparatus (10) for recovering compounds from a feed by electrodialysis, comprising an anode (1), a cathode (2) and a plurality of ion exchange membranes (3, 4) arranged between the anode and the cathode so as to form a stack of successive electrodialysis cells (17). Each cell comprises a feed compartment (5), a concentrate compartment (6) and at least two ion exchange membranes (3, 4), being a cation exchange membrane (3) and an anion exchange membrane (4), or a bipolar membrane (9) and either one of a cation exchange membrane (3) and an anion exchange membrane (4). The feed compartment (5) and the concentrate compartment (6) of each cell are separated by one of the at least two ion exchange membranes. According to the invention, at least one porous filtration membrane (11, 12) is stacked in the feed compartment (5) of each cell to form a barrier between the feed stream and one of the ion exchange membranes.In use, a pressure difference across the at least one porous filtration membrane is 0.5 bar or less, such that the porous filtration membrane acts solely as a physical barrier without there being a pressure driven filtration through the porous filtration membrane.A method for recovering compounds from a feed by electrodialysis is provided as well.

    摘要: To prevent biological fouling in an electrodialysis device, a membrane electrolysis stack and an electrodialysis device including this membrane electrolysis stack are created. The electrodialysis device preferably serves for the regeneration of an electroless plating bath, for example a nickel plating bath. It comprises at least one anode An and at least one cathode Ca as well as respectively a membrane electrolysis stack arranged between an anode An and a cathode Ca, every membrane electrolysis stack comprising membranes stacked on top of each other and respectively electrolyte compartments arranged therebetween, at least one first and at least one second membrane alternating in succession in the membrane electrolysis stack. At least one first membrane is selected from a group comprising an anion exchange membrane A and a bipolar membrane BP, and at least one second membrane is selected from a group comprising a monoselective anion exchange membrane MSA, a monoselective cation exchange membrane CSA and a proton-selective exchange membrane, with the proviso that the at least one first membrane and at least one second membrane in the membrane electrolysis stacks are respectively selected independently of each other and that at least one first membrane in the membrane electrolysis stack is a bipolar membrane BP. Furthermore, it is provided that the electrolyte compartments located on the cathode side to the at least one first membrane are diluate compartments Di1, Di2 in which the electrolyte to be regenerated is contained, and that the electrolyte compartments located on the cathode side to the at least one second membrane are concentrate compartments Co1, Co2, Co3 in which interfering ions taken up from the electrolytes to be regenerated are contained.

    摘要: A device for isoelectric focusing. The device comprises a focusing container configured to contain an electrolyte solution and having a longitudinal axis and at least one electrolysis unit mounted in a close proximity to the longitudinal axis. Each electrolysis unit injects an ion flow into the focusing container so as to create a pH gradient having a plurality of steps in the electrolyte solution, along the longitudinal axis. Each step has a substantially uniform pH level and the pH gradient is defined by at least one pH ramp between every two sequential steps of the plurality of steps.
