Domestic Water Supply - Lime Deposits

Lime deposited vs. temperature and water consumption.

Lime deposited in water supply systems - based on 170 mg/liter dissolved calcium and magnesium (hard water):

domestic water supply system lime deposits

Lime deposits increase with temperature due to less calcium carbonate solubility at higher temperatures.

Example - Deposits from Consumption of Hard Water

The deposits from hard water with 170 mg dissolved calcium and magnesium per liter, temperature 60 ^oC and water consumption 2000 m³/year - can from the diagram above be estimated to aprox.

5 kg/year
