A cooling system is provided having a first heat exchanger for heating a cooling liquid, a second heat exchanger, which preferably comprises an evaporator, for cooling the cooling liquid, and a pump for guiding the cooling liquid through the first and second heat exchanger. The system includes a pellet reactor through which cooling liquid is fed, so as to remove impurities from the cooling liquid by grafting the impurities onto graft material in the pellet reactor. A method is also provided for using such a cooling system. An advantage of the system is especially that calcium salts can be grafted onto the graft material, as a result of which the concentration factor of the cooling system can be increased significantly.

We claim: 1. A cooling system comprising a first heat exchanger (3) for heating a cooling liquid and a second heat exchanger (5), which comprises an evaporator, for cooling the cooling liquid, a pump (1) for guiding the cooling liquid through pipes (2, 4, 6) and through the first and second heat exchangers (3, 5), a drain (13) for discharge of cooling liquid from the system and a supply (12) for addition of fresh cooling liquid into the system, wherein the system is connected to a pellet reactor (7) having an inlet (9) and an outlet (10) for cooling liquid, the inlet (9) being connected to any of the pipes (2, 4, 6) of the system by a conduit (8) for withdrawing liquid from the system, the outlet (10) being connected to any of the pipes (2, 4, 6) of the system by a conduit (11) for feeding cooling liquid from the pellet reactor (7) back to the system, and the pellet reactor (7) comprising a graft material for grafting impurities from the cooling liquid thereon. 2. The cooling system according to claim 1, wherein the pellet reactor (7) comprises a supply (15) for fresh graft material at a first level and a discharge (16) for loaded graft material at a second level. 3. The cooling system according to claim 1, wherein the inlet (9) of the pellet reactor (7) is at a position below the outlet (10) of the pellet reactor (7). 4. The cooling system according to claim 3, wherein the inlet (9) is near a bottom of the reactor (7) and the outlet (10) is near a top of the reactor (7). 5. The cooling system according to claim 1, wherein the system comprises a supply (17) for adding a CO32- providing compound to the cooling liquid to be treated in the pellet reactor (7). 6. The cooling system according to claim 5, wherein the CO32- providing compound comprises gaseous CO2. 7. The cooling system according to claim 1, wherein the system comprises a supply (14) for adding a pH-regulating agent to the cooling liquid to be treated in the pellet reactor (7). 8. A cooling system comprising a first heat exchanger (3) for heating a cooling liquid and a second heat exchanger (5) for cooling the cooling liquid, a pump (1) for guiding the cooling liquid through pipes (2, 4, 6) and through the first and second heat exchanger (3, 5), a drain (13) for discharge of cooling liquid from the system and a supply (12) for addition of fresh cooling liquid into the system, wherein the system is connected to a pellet reactor (7) having an inlet (9) and an outlet (10) for cooling liquid, the inlet (9) being connected to the supply (12) for the addition of fresh cooling liquid and the outlet (10) being connected to any of the pipes (2, 4, 6) of the system for feeding fresh cooling liquid by a conduit (11) from the pellet reactor (7) into the system, and the pellet reactor (7) comprising a graft material for grafting impurities from the fresh cooling liquid thereon. 9. The cooling system according to claim 8, wherein the second heat exchanger (5) comprises an evaporator. 10. A method for treating a cooling system comprising: a first heat exchanger (3) for heating a cooling liquid and a second heat exchanger (5), which comprises an evaporator, for cooling the cooling liquid, a pump (1) for forcing the cooling liquid through pipes (2, 4, 6) and through the first and second heat exchanger, a drain (13) for discharging cooling liquid from the system, and a supply (12) for adding fresh cooling liquid into the system, wherein the method comprises the steps of: providing a pellet reactor (7) comprising an inlet (9) and an outlet (10), feeding liquid into the inlet (9) of the pellet reactor (7) from the cooling system and returning liquid from the outlet (10) of the pellet reactor (7) back into the cooling system, and removing impurities from the cooling liquid which is fed through the pellet reactor (7) by grafting the impurities on a graft material which is provided in the pellet reactor (7). 11.
