Abstract:
[Problem] To adjust hydrogen ion concentration by adjusting the ingredients of a liquid. [Solution] In the present invention, only particles with a specific size or smaller are allowed to pass through a membrane device 15 (membrane 5) by filtration and/or by dialysis, and a specific ingredient that has passed through the membrane is adsorbed to an ion exchange resin 7 (means for adsorption) for ingredient adjustment, is subjected to pH adjustment by a pH adjustment device 22, and is fed back to the membrane device 15 (membrane 5) and circulated. If the pH after the ingredient adjustment is outside a prescribed range, the pH is adjusted (steps 03 and 05). If the difference in the pH between before and after passage through the membrane device 15 is outside a prescribed range, the pH is adjusted (steps 07 and 08). If the variation in pH at various sites after passage through the membrane device 15 is outside a prescribed range, the pH is adjusted (steps 11 and 12). If the variation in the pH at various sites before passage through the membrane device 15 is outside a prescribed range, the pH is adjusted (steps 16 and 17). If the differences in pH are within prescribed ranges, pH adjustment ends (steps 06, 09, 13 and 18).
