Hard Water and Scale

What this symptom may mean

Calcium and magnesium hardness may form deposits as temperature, pressure, pH and concentration change; other deposits can look similar.

Information and testing priorities

• Test hardness, alkalinity, pH, conductivity/TDS and temperature; inspect or analyze the deposit; record flow and differential pressure.

Responsible treatment pathway

• Cleaning, softening, chemistry control, filtration or a Puroxi Descaler may be considered according to the deposit mechanism and objective.

Urgency

Address before heat transfer, flow or equipment life is materially affected.

What to send Puroxi

• Complete laboratory report and sampling date
• Source, intended use, volume, flow and photographs
• History of the symptom and existing equipment or treatment
• Required outcome and any applicable health, animal, process or discharge requirements
