Lime Dosage Calculator

Enviraj Consulting

Calculate Lime Dosage Requirement in Sedimentation Process

Raw Water Alkalinity (mg/L)

Alum Dose (mg/L)

Residual Alkalinity (mg/L)

Additional Alkalinity Requirement (mg/L)	Required Lime Dose (mg/L)

Note:

A dose of 1 mg/L of aluminium sulphate reacts with 5.3 mg/L of alkalinity expressed as CaCO3 [1]
Hydrated lime (Ca(OH)₂) is considered in the lime dosage calculations
Hydrated lime CaCO3 equivalvent factor = 1.35
