A method provides for the production of a concentrate for dialysis, the composition of which can be adapted individually to the respective needs of the patient. The special components required individually are added in the form of highly concentrated special concentrates with a volume of 10-500 mL to 3-10 liters of standard concentrate. The two solutions are then mixed thoroughly by compressed air, which is blown through a concentrate intake rod into the solution from a compressed air source in the dialysis machine.
