What is Water Hardness?
Water hardness refers to the total concentration of calcium ions (Ca²⁺) and magnesium ions (Mg²⁺) in water, typically measured in milligrams per litre (mg/L) as calcium carbonate (CaCO₃). This key parameter determines whether your water is classified as “hard” or “soft” and significantly impacts various applications.
The Critical Importance of Monitoring Hardness
For industrial water systems, particularly boilers, monitoring total hardness is essential to prevent serious operational issues:
Scaling Problems
- Reduced Efficiency: Scale buildup dramatically decreases heat transfer, increasing fuel consumption by up to 25%
- Equipment Damage: Scaling causes metal overheating, reducing mechanical strength and equipment lifespan
- Maintenance Costs: Regular descaling operations require downtime and expensive chemicals
Corrosion Risks
- Under-deposit corrosion can lead to sudden equipment failure and costly repairs.
- Localized pitting corrosion often remains undetected until significant damage occurs
Quality Issues
- Hard water can affect steam purity and compromise manufacturing processes.
- Foaming and carryover problems reduce overall system reliability
