Abstract:
A water treatment system (1) includes a deionization unit (10) and an ion-selective removing unit (20). The deionization unit (10) includes a pair of opposing electrodes that is charged to have polarities opposite to each other, a flow passageway positioned between the electrodes and enabling passage of water containing ions, and an ion-exchange membrane that is disposed on the flow passageway side of each of the electrodes, and performs a deionization process of deionizing the water containing the ions by allowing the ions to be adsorbed onto the electrodes and a regeneration process of eliminating the ions from the electrodes. The ion-selective removing unit (20) is disposed on the downstream side or upstream side of the deionization unit (10) to separate and remove divalent or more ions from the water containing the ions because the ratio of removing the divalent or more ions that are the scale component among the ions is relatively higher than the ratio of removing monovalent ions from the water containing the ions. The water treatment system (1) can increase the ratio of removing scale component ions.
Abstract:
Apparatus for purifying a fluid, which comprises an ion absorption cell (2) traversed by a fluid to be treated (F1) containing cationic particles and/or anionic particles, provided with a containment structure (3) defining at its interior two operating chambers (4, 5) traversed by the fluid to be treated (F1), and each delimited by a respective electrode (10, 11) that can be power supplied to opposite polarities. Between the two operating chambers (4, 5), a third evacuation chamber (13) is interposed, containing a porous electrical conductor (18) traversed by a washing fluid (F2) and delimited by two opposite walls (16, 17) which together with the electrodes (10, 11) define the aforesaid operating chambers (4, 5). The aforesaid walls (16, 17) have at least one ion-selective area associated, which is susceptible to being traversed by charged particles with corresponding polarity contained in the two contiguous operating chambers (4, 5) subjected to the action of the electric field generated by the electrodes. The porous electrical conductor (18) is in turn susceptible to reduce the electric field inside the third evacuation chamber (13) such that the ion-selective areas of the walls of the third evacuation chamber (13) are capable of repelling the charged particles with corresponding polarity contained in the third evacuation chamber (13) and subjected to the action of the electric field reduced due to the shielding effect of the porous electrical conductor (18).

Abstract:
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren sowie eine Einrichtung zu schaffen, welche die Entfernung von Verunreinigungen aus Abwässern mit gutem energetischem Wirkungsgrade zuverlässig garantiert, wodurch das gereinigte Wasser als Direkteinleiter eingespeist werden kann oder in speziellen Fällen einem weiteren Reinigungsprozess zugeführt werden kann. Ein weiterer Aspekt dieser Aufgabe ist die Rückgewinnung von Rohstoffen aus landwirtschaftlichen und kommunalen Abwässern bzw. solchen aus Biogasanlagen. Diese Aufgabe wird durch ein Verfahren gelöst, das eine elektrolytische Behandlung des Abwassers umfasst unter Verwendung einer Anode, welche sowohl der Elektrolyse widerstehende Materialien als auch bei der Elektrolyse in Lösung gehende, sogenannte Opfermaterialien enthält, die beide gleichzeitig dem Abwasser ausgesetzt werden. Eine Einrichtung zur Durchführung des Verfahrens weist als der der Elektrolyse widerstehenden Teil der Anode einen formstabilen Anodenkäfig (4) aus Platin, Titan, Niob, Palladium, Ruthenium oder platiniertem Titan auf, der mit Aluminium, Eisen, Magnesium, Calcium oder mit Gemischen dieser Metalle als Opfermaterial bestückt ist. Die Erfindung ist zur Abwasserbehandlung anwendbar.

Abstract:
Disclosed herein is a unit for a salt water pool chlorinator that is arranged for water to flow therethrough. The unit is configured for an electrode assembly to be received therein and is arranged such that some of the water flows through the electrode assembly. The unit has a channel, defined by a barrier impermeable to water, arranged for some other of the water to flow through the channel. At least one port may be arranged at the channel whereby at least one of a sensor, a feeder and an extractor can use the port to respectively detect, feed into and extract water in the channel.
