<p>PROBLEM TO BE SOLVED: To provide a solution preparing apparatus advantageous from an aspect of cost, not requiring an air filter for preventing the penetration of bacteria or the like into a dissolving tank and enabling the miniaturization of the apparatus as a whole and the reduction of an operation sound. SOLUTION: The solution preparing apparatus includes a chamber 2 partitioned into two chambers 21 and 22 by a movable partition wall 23, a dissolving liquid supply line 1 for supplying a dissolving liquid to the first chamber 21 of the chamber 2, the dissolving tank 5, solution preparing lines 31 and 32 for connecting the dissolving tank 5 and first and second chambers 21 and 22, a densitometer N, a transfer pump 4, a solution transfer line 6 for transferring the solution housed in the second chamber 22 to a use point and a powder supply means 7. The dissolving tank 5 is a U-shaped tank consisting of an upstream tank 51 having a relatively fine diameter and a downstream tank 52 having a relatively thick diameter and filters 55 and 56 are provided on the downstream side of the downstream tank 52.</p> |
