PROBLEM TO BE SOLVED: To effectively construct a water treatment system.SOLUTION: An apparatus category of which the outlet water quality meets the quality of treated water is searched for, based on the quality of treated water (S16), and the obtained apparatus category is selected as the apparatus category of the final stage (S17). Whether the inlet water quality of the apparatus category of the final stage meets the quality of raw water or not is determined (S18). When it is determined that the inlet water quality of the apparatus category of the final stage does not meet the quality of raw water, another apparatus category of which the outlet water quality meets the inlet water quality of the previously selected apparatus category is searched for (S19) and selected as the apparatus category of the previous stage (S20). A step of S18 for selecting the apparatus category of the previous stage is repeated in order until the inlet water quality of the selected apparatus category meets the quality of raw water. When the inlet water quality of the selected apparatus category meets the quality of raw water, the procedure for searching is terminated. A combination of thus selected apparatus categories is output as a construction of the water treatment system (S21). |
