Calcium addition to water

Calculates the calcium required to increase Ca concentration in water – either by dosing lime suspension or saturated limewater.

Calcium addition in water

This calculator compares Ca concentration in raw and target treated water and computes the required calcium dose. You can choose between dosing lime suspension or saturated limewater. Results are indicative only – real doses must be confirmed in practice.

Raw and target water

Calcium in raw water [mg/l]

Calcium in treated water (target) [mg/l]

Treated water production [l/s]

Calcium addition mode

Mode: lime suspension

Inert fraction in lime [%]

Lime suspension concentration [%]

Raw and target water

Required Ca increase (target − raw) [mg/l]: –

Q: – m³/h

Mode: lime suspension

Calcium content in lime [kg Ca/kg lime]: 0.486

Required lime mass [g/m³]: –

Lime suspension dose [l/m³]: –
