Claims (17)

42351/2 CLAIMS;
1. A process for softening water by rendering the water alkaline i a reactor with a fluidized granular bed and removing hardness constituents in granular form, wherein the water is rendered alkaline by addition of an alkali metal hydroxide solution, the water and the alkali metal hydroxide solution being separately injected into the reactor such that the inflow direction of the water through inlets into the reactor forms an angle with the general current direction within the reactor and the alkali metal hydroxide solution flows into the reactor at a level above the water inlets.
2. A process as claimed in claim 1, wherein the alkali metal hydroxide solution is sodium hydroxide solution.
3. A process as claimed in claim 1 or 2, wherein the alkali metal hydroxide solution and the water are discharged into the reactor at several places smiltaneously.
4. A process as claimed in any preceding claim, wherein the water and the alkali metal hydroxide solution are injected into the reactor from the base of the reactor.
5. A process as claimed in any preceding claim, wherein the alkali metal hydroxide solution and the water are injected into the reactor at an angle with respect to the general liquid displacement in the reactor.
6. A process as claimed in any preceding claim, wherein the angle between the injected liquid direction and the general current direction is substantially 90°.
7. A process as claimed in any preceding claim, wherein the alkali metal hydroxide solution is injected into the 42351/2
8. A reactor with a space for maintaining a fluidized granular bed in an aqueous liquid, a bottom wall and feeding and discharging channels for water to be softened, and for alkali metal hydroxide solution, wherein one or more water spray nozzles are provided in the base, the discharge channels of which are oriented such tha the center line of these channels forms an angle with the general current direction of liquid in the reactor, and one or more alkali metal hydroxide solution spray nozzles, the discharge channels of which, with respect to the reactor base, are positioned at a higher level than the discharge channels in the water spray nozzle.
9. A reactor as claimed in claim 8, wherein several separate alkali metal hydroxide solution spray nozzles and several separate water nozzles are provided.
10. 11). A reactor as claimed in claim 8 or 9, wherein fehe discharge channels of the alkali metal hydroxide solution spray nozzles are also oriented such that their center line forms an angle with the general current direction of the liquid in the reactor.
11. A reactor as claimed in claims 8, 9 or 10, wherein the angle between the center line of the discharge channels and the general current direction of the liquid amounts to 90°.
12. A reactor as claimed in claims 8,9,10 or 11, wherein the alkali metal hydroxide solution spray nozzles are positioned concentrically within a ring of water discharge openings, the ring being perpendicular to the general current direction of the liquid. 42351/2
13. A reactor according to any of claims 8 to 12, wherein the reactor is provided with two separate chambers adjacent the base, one of which chambers serves for feeding water and the other serves for feeding alkali metal hydroxide solution, which chambers are respectively connected via water and alkali metal hydroxide solution feeding lines to the spray J ■:.·-nozzles provided in the bottom wall of the reactor.
14. A reactor according to claim 13, wherein the water chamber adjoins the actual bottom of the reactor.
15. A reactor according to claim 14, wherein the reactor comprises a cylindrical container in which both chambers are formed by two partitions provided in the container and parallel to the bottom thereof, and wherein the spray nozzles are provided in the second partition above the container base, which second partition forms the actual reactor bottom, while the water feeding lines to the spra nozzles are directly connected with the water chamber immediately below them and the alkali metal hydroxide solution chamber which is below said water chamber is connected with the alkali metal hydroxide solution feeding lines of the alkali metal hydroxide solution spray nozzles by means of channels passing through the water chamber.
16. A process for softening water substantially as hereinbefore described with reference to the examples.
17. A reactor substantially as hereinbefore described with reference to the accompanying drawings.
