pH、氧化还原电位调节水的制造装置
摘要：
本发明的pH、氧化还原电位调节水的制造装置，在超纯水(W)的供给线(1)上设有铂族金属负载树脂柱(2)，在此后段具备pH调节剂注入装置(3A)和氧化还原电位调节剂注入装置(3B)。在此装置(3A、3B)的后段依次具有膜式脱气装置(4)和气体溶解膜装置(5)，在气体溶解膜装置(5)连通有排出线(8)。排出线(8)的途中，设有pH计(10A)和ORP计(10B)，这些pH计(10A)和ORP计(10B)，与控制装置(11)连接。另外，基于pH计(10A)和ORP计(10B)的测量结果，来控制pH调节剂注入装置(3A)和氧化还原电位调节剂注入装置(3B)的注入量。根据该pH、氧化还原电位调节水的制造装置，能准确地调节pH和氧化还原电位。
摘要（英）：

An apparatus for producing an aqueous pH- and redox potential-adjusting solution is provided with a platinum group metal-loaded resin column 2 in a supply line 1 for ultrapure water W and subsequent thereto, is provided with a pH-adjusting agent-infusing device 3A and a redox potential-adjusting agent-infusing device 3B. Subsequent to said devices 3A and 3B, the apparatus has a membrane-type degasification device 4 and a gas-dissolving membrane device 5 in succession, and the gas-dissolving membrane device 5 is in communication with a discharge line 8. A pH meter 10A and an ORP meter 10B are provided partway in the discharge line 8, and said pH meter 10A and ORP meter 10B are connected to a control device 11. On the basis of the measurement results of the pH meter 10A and the ORP meter 10B, the infusion amounts of the pH-adjusting agent-infusing device 3A and the redox potential-adjusting agent-infusing device 3B are controlled. With said apparatus for producing an aqueous pH- and redox potential-adjusting solution, it is possible to accurately adjust pH and redox potential.
