That calculation may also be easily done by modeling it with a simulator capable of modeling polar environments. For the experiment A, the boundary value concentration at which the target corrosivity index is 0 was calculated, and the results are summarized in Table 3. In [Formula 14], [Ca 2+ ] i is the calcium hardness of the incoming source of constant water and [Ca 2+ ] t is the target calcium hardness. When the Langerhree index is negative, the constant raw water is evaluated as corrosive water quality, and when it is not negative, the constant raw water is evaluated as toxic water quality. t. The corrosion index changes depending on the calcium hardness and the hydrogen ion concentration of the raw water that is changed depending on the addition of the corrosion inhibitor, and the corrosion index of the treated water can be calculated more than once. There are plenty of techniques, e.g., cathodic protection [2,3], organic coatings [4-6], . The controller 300 may be configured to control the injection amount of the corrosion inhibitor in the supply unit 400 using the corrosiveness index of the raw water. When the hydrogen ion concentration was fixed at 8.5 and the calcium hardness was increased to 50, 60, 80 and 100 mg / L, the alkalinity was increased to 46, 56, 76 and 96 mg / L, 0.04, 0.12, 0.38, and 0.58, respectively. The reasons for estimating the amounts of calcium hydroxide and carbon dioxide injected as described above are as follows. The present invention relates to a method for evaluating corrosion inhibition on water quality of raw water using a computer or dedicated hardware using Langley's index and evaluating corrosion inhibitors added to suppress the corrosion of the raw water when the raw water is corrosive And a method for estimating an optimal injection amount.
