  • Patent number: 11319222
    Abstract: A method of removing cations from water and a process arrangement for performing the method, wherein the method includes containing cations selected from a group consisting of Se, As, Sb, Cr, Mn, Mo, W, V, Te, P, Si including preparing an iron precipitate-containing sludge by electrochemical water treatment, wherein the water is led through an electrochemical water treatment unit, wherein electricity dissolves iron from an anode to the water thereby forming an iron precipitate-containing sludge to which cations to be removed are adsorbed/co-precipitated, adsorption and co-precipitation enhancing to provide a very high density sludge having an iron precipitate concentration of 50-400 g/l thereby further adsorbing cations contained in the water, and separating solids from the obtained sludge thereby producing treated water having a reduced cation content and solids comprising iron precipitate compounds and adsorbed/co-precipitated cation compounds.

  • Patent number: 10287181
    Abstract: An electrochemical reactor for electrochemically treating water, including a shell structure defining an inner space. The shell structure further includes an inlet portion having an inlet for conducting a water flow to the inner space, and a reactor chamber in flow connection with the inlet portion, and preferably with an outlet portion. The inlet is arranged such that the water flow to the inner space is directed away from the reactor chamber so as to cause the water flow to mix by forcing the water flow to change direction before entering the reactor chamber. A water treatment apparatus having such a reactor, and the use of such a reactor are also disclosed.

  • Patent number: 7590629
    Abstract: SyncML is used for synchronizing data of terminal device in wireless and wired environments. In general, synchronization takes place between a terminal device (e.g., a mobile phone) and a server device (e.g., a web server in Internet). However, a SyncML session, which occurs between the terminal and server, is an end-to-end communication. The idea of the present invention is to provide a method, a router and a system to allow routing of the synchronizing data exchanged during a synchronizing session through such a router. In general having the router is more cost efficient and a faster solution from the end-user point of view.

  • Publication number: 20080257823
    Abstract: The invention relates to a process for producing an adsorbent material containing iron oxyhydroxide, wherein an iron oxyhydroxide mass having a moisture content of 5-15% by weight is produced, said mass is granulated by compaction, followed by comminution and sieving of the compacted product to give product granules with grain sizes ranging between 0.5 and 4 mm. The invention is also relates to a granular adsorbent material containing iron oxyhydroxide, the grain size of the granules being between 0.5 and 4 mm, and the bulk density thereof being from 0.8 to 1.5 g/cm3. Said adsorbent material may be used for removing harmful substances, particularly arsenic, from an aqueous solution thereof.

  • Patent number: 7308642
    Abstract: SyncML allows synchronization to take place between a terminal device and a server device. To be able to understand each other the data transferred between a SyncML client and a SyncML server must be coded as a SyncML document. The coding or decoding/parsing of the SyncML document is done by the separate application components, respectively, that other end-user applications (e.g. a UI application) can use. It is not always wanted, advantageous or even possible to employ the SyncML coding/decoding feature, since it is subjected to several disadvantages. The present disclosure provides a concept to still use the synchronization related components for communicating synchronization data between the participating devices but without employing the coding/decoding component feature. The response of coding and decoding the synchronization data is transferred to corresponding end-user applications.
