Water Design is a PC-based software tool sufficient for developing many
aspects of water-pinch analysis and synthesis covered in Chaps. 1 to 7 of Industrial

- Unzip waterdesign.zip using a program such as WinZip
- Double-click on Water Design.exe to run the program
You may need to install the Visual Basic 6 run-time files if you receive an error stating that COMDLG32.OCX or another file is missing when you try to run Water Design.
The installation for these files is found on the Microsoft support webpage.
Look for the link to download VBRun60.exe.

Figure 1a. Constructing the concentration-composite curve (steps 1 and 2).
Figure 1b. Constructing the concentration-composite curve (step 3).
Figure 1c. Constructing the concentration-composite curve (step 4) and water-supply
Figure 1d. Water Design gives the concentration-composite curve (red)
and apparent water-supply line (blue) for Example 1.
Figure 1e. Water Design displays an optimum water-using network. The
blue lines represent freshwater. The green lines display water reuse. The red
lines show effluent streams. The box display: (1) the operation specifications
of water-using operation 2; (2) its reuse (water source) from other operations;
and (3) its reuse (its effluent being reused) by other operations.
