<p>Replace all metal pipes for plastic </p>

Chilled water is used for production equipment cooling. Suddenly pH of the water started to drop. The aim of the project is to analyze the issue, understand the root cause, and propose solutions to the problem.

Cooling water issues

Electrical potentials difference exists between the parts (flanges)

Electrical current occurs through the cooling water between the parts (flanges)

Corrosion occurs between metal parts (flanges)

Replace the water when the parameters (pH and conductivity) got out of the spec limits

Connect the flanges with wire to ensure equal potential

Replace the water continuously to ensure low conductivity of the water

Ground all the metallic parts (pipes, flanges) to ensure equal electrical potentials

Replace all the metal pipes with plastic pipes
