### Chlorine Dosage Calculator - Rate of Dose, Demand, Water Residual Values

Calculate rate of dose, demand and residual values in a water using this free chlorine dosage calculator tool.

Formula:

### Chlorine Dosage (mg/L) = Demand (mg/L) + Residual (mg/L)

Note : Type any two known values for calculation

# Chlorine Dosage Calculator

 Enter the Residual Value : mg/L Enter the Demand Value : mg/L Enter the Dose Value : mg/L

Example 1: What is the chlorine dose, if the chlorine demand is 4.8 mg/L and the chlorine residual is 2 mg/L?
Dose (mg/L) = Demand (mg/L) + Residual (mg/L)
= 4.8 mg/L + 2 mg/L
= 6.8 mg/L

Example 2: What is the chlorine demand in milligrams per liter if the chlorine dose is 3.2 mg/L and the residual is 0.3 mg/L?
Demand (mg/L) = Dose (mg/L) – Residual (mg/L)
= 3.2 mg/L - 0.3 mg/L
= 2.9 mg/L

Example 3: What is the chlorine residual, if the chlorine demand is 1.8 mg/L and the chlorine dose is 10 mg/L?
Residual (mg/L) = Dose (mg/L) – Demand (mg/L)
= 10 mg/L – 1.8 mg/L
= 8.2 mg/L
