The method comprises the steps of: i) introducing a portion of dirty solution into a chemical reactor; ii) introducing one or more flocculations and/or precipitation chemicals into the reactor; iii) allowing the chemicals to react with the dirt; and iv) removing the cleaned solution from the reactor. The invention also relates to a device for carrying out the method. By use of the method, it is possible to clean the dirty solution to obtain a cleaned solution having a turbidity below 100 NTU, preferably below 50 NTU, more preferably 25 NTU, and thereby the solution can be reused several times.</p> |
