摘要:
A water softening device (100) comprises a filter (105) which is configured to decrease hardness of a first stream of raw water to produce a second stream of water with decreased hardness, a first sensor (109) for measuring an electrical property of the first stream and a second sensor (110) for measuring an electrical property of the second stream. The sensors are able to measure an electrical property of the first stream and an electrical property of the second stream. The ratio of the measured properties can be used as an indicator to estimate the exhaustion state of the filter.

Provided is an underwater holding-type lithium recovering apparatus 1000 including: an underwater holder 100 installed on an offshore sea bed; a lithium adsorbent 200 held in the underwater holder 100 and adsorbing lithium ions contained in seawater; a moving ship 300 installed with a cleaning tank 320 cleaning the lithium adsorbent 200 transferred from the underwater holder 100 and a desorbing tank 330 desorbing lithium ions adsorbed in the lithium adsorbent 200 transferred from the cleaning tank 320, and moved to a coastline when lithium ions of a reference value or more are filled in the desorbing tank 330; and a transfer pump 400 transferring lithium ions filled in the desorbing tank 330 to a reservoir 500 installed at the coastline.
摘要:
A method of sorbent dialysis is provided for enhanced removal of uremic toxins, such as toxic anions and/or organic solutes, from spent dialysate. More highly adsorbable zirconium polymeric complexes of these anions and/or organic solutes can be initially formed in spent dialysate by treatment with zirconium salt solution or other zirconium cation source, and then removed with adsorbent to provide purified or regenerated dialysate. Sorbent dialysis systems for detoxifying spent dialysate containing toxic anions and organic solutes are also provided.
摘要:
A device and method for conditioning an aqueous liquid, e.g. drinking water, includes at least one outlet for the conditioned liquid; at least one inlet (1) for receiving a flow of liquid to be treated; and at least first, second and third liquid treatment sections (3,4,5), arranged in parallel in flow sense, each containing a liquid treatment medium including at least one ion exchange material. The device is arranged to create at least three sub-flows of liquid from a first flow of liquid to be treated by distributing the first flow over the first, second and third liquid treatment sections (3,4,5). The device is arranged to obtain at least a bypass flow of liquid, to conduct the bypass flow through the device so as to bypass each of the first, second and third liquid treatment sections (3,4,5) and to unite the bypass flow with the at least three sub-flows upstream of the at least one outlet. Use of the described device to condition drinking water, including using the conditioned drinking water to produce a beverage by extraction, for example coffee.
摘要:
The invention relates to a cooling device (10) for a functional system, in particular a fuel cell system (12), in particular for a motor vehicle. The cooling device (10) comprises a line system (14, 22) for a cooling fluid connected to the functional system (12) for cooling. A tank (20) of the cooling device (10) for the cooling fluid is fluidically connected to the line system (14, 22). A preparation unit, in particular an ion exchanger (24), for preparing the cooling fluid is fluidically connected to the line system (14, 22). The tank (20) comprises a receptacle for the preparation unit (24) and/or an ion exchanger (24) disposed so as to stand in the tank (20).
摘要:
Die Erfindung betrifft eine Wasseraufbereitungskartusche (2), mit einem Gehäuse (12), das einen lonenaustauscher (34) umschließt und sich über ein Schraubgewinde (14, 16) an einer Kartuschenanschlussarmatur (4) anschrauben lässt, die einen mit Rohwasser, insbesondere aus einem Wasserversorgungsnetz, beaufschlagbaren Wassereinlass (6) und einen mit einem Verbraucher, insbesondere einer Getränkemaschine, verbundenen oder verbindbaren Wasserauslass (8) aufweist. Damit sich die Wasseraufbereitungskartusche (2) nur an einer bestimmten Kartuschenanschlussarmatur (4) anschrauben lässt, die für diesen Typ von Wasseraufbereitungskartusche (2) vorgesehen ist, wird erfindungsgemäß vorgeschlagen, das Gehäuse (12) und die Kartuschenanschlussarmatur (4) jeweils mit mehreren ringförmigen, konzentrisch zur Gewindeachse (26, 68) des Schraubgewindes (16, 14) angeordneten Kodierrippen (56, 58, 60 bzw. 62, 64, 66) zu versehen, die beim Anschrauben des Gehäuses (12) an der Kartuschenanschlussarmatur (4) ineinander greifen.
摘要:
The invention relates to a water treatment device for treatment of drinking water from mains water. At least the interior of the housing of said device is cylindrical. Said housing comprises sections arranged on top of each other through which mains water to be purified flows. The individual housing sections are in the form of replaceable filter cartridges.
