How do you determine if local water is suitable for use in UHP waterjetting, particularly in areas where potable water is scarce?


Selected Answers

From Jaime Marcos of Profesional independiente on October 20, 2020:
Depending on what you want to achieve with high pressure cleaning, all types of water can be used. You only have to be restrictive if a coating is applied later, if you have to use potable, demineralized water, etc. The ISO8501-4 Standard defines: Water pressure, water volume, nozzle design, stand-off distance and traverse rate are factors which will affect the efficiency of removal of contaminants such as water-soluble matter, rust and paint coatings. The removal efficiency also depends on whether detergents are being used in the cleaning process. If so, rinsing afterwards with clean water is necessary. It does not define water quality.
