摘要： Die Erfindung betrifft ein Verfahren zur In-situ-Regenerierung von mit Trihalomethanen (THM) beladenen Aktivkohlen. Erfindungsgemäß wird dies durch alkalische Hydrolyse der THM bei erhöhten Temperaturen innerhalb der Aktivkohle in halogenfreie, gut wasserlösliche oder gasförmige Verbindungen erreicht. Nach Abschluss der chemischen Hydrolysebehandlung wird die Aktivkohle durch Spülen mit Wasser und verdünnten Säuren von Reagenzien und Reaktionsprodukten befreit und steht für eine erneute Beladung im Rohwasserstrom zur Verfügung. Während des gesamten Reinigungsvorgangs muss das Aktivkohlebett nicht bewegt werden.

摘要： An apparatus for mixing a first fluid into a flow path (44) of a second fluid, said apparatus having a chamber (12), which encloses the flow path and exhibits a first inlet (13) for receiving the second fluid, a second inlet (15) arranged downstream of the first inlet for receiving the first fluid, as well as an outlet arranged downstream of the second inlet for discharging a mixture of the first fluid and the second fluid, said flow path extending from the first inlet to the outlet and said second inlet opening into the flow path, a throttle body (29), which is pivotally arranged inside the chamber for controlling the flow area of the flow path, and pivoting means (50, 51) for pivoting the throttle body for said controlling of the flow area. According to the invention, the pivoting means is adapted to pivot the throttle body so that the flow area decreases with a decreasing flow rate of the second fluid and increases with an increasing flow rate of the second fluid, in order to maintain the flow velocity of the second fluid at the second inlet within a predetermined range.

摘要： The present invention concerns a hydrocyclone for cleaning cellulose suspensions from light impurities i.e. a so called reverse hydrocyclone, having a base end and an apex end and a separation chamber having an elongated shape between the base end and the apex end, at least one inlet arranged at the base end and at least one underflow outlet at the apex end and at least one overflow outlet at the base end. The overflow outlet is provided with an additional, light reject outlet arranged concentrically to a length axis of the hydrocyclone. The invention also concerns a system and a method for producing and/or treating cellulose suspension comprising at least a reverse cleaning stage and at least a dewatering stage.

摘要： An assembly with hydrocyclones comprising: multiple hydrocyclones having a inlet chamber with two side openings positioned on opposite sides of the inlet chamber and a overflow chamber having two side openings positioned on opposite sides of the overflow chamber. The hydrocyclones are arranged at a support structure, comprising a support bar for support of the hydrocyclones. The hydrocyclones being arranged side by side with their side openings adjacent each other thus forming an inlet pipe by means of the inlet chambers and an overflow pipe by means of the overflow chambers. The inlet chambers and the overflow chambers being adapted to be pressed against each other respectively. The hydrocyclones being arranged in pairs with one of the two hydrocyclones arranged on one side of the support bar and the other on the opposite sides thereof. A method assembling multiple hydrocyclones, wherein hydrocyclones are hung on a support bar at a base end or a head portion and are pressed together, is provided, and a support structure for an assembly of hydrocyclones, comprising a support bar, an end bar and one or two underflow pipes.
