Water Softener Salt Usage Calculator

Calculate Salt Usage







Formula

To calculate the Salt Usage (\(SU\)):

\[ SU = \left( \frac{H \cdot U \cdot P \cdot 30}{C} \right) \cdot 8 \]

What is Water Softener Salt Usage?

Water softener salt usage is the amount of salt a water softening system uses to remove minerals from hard water. The system works by exchanging the minerals for sodium ions in a process called ion exchange. The amount of salt required depends on the water hardness, the capacity of the softener, and the water usage of the household.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ SU = \left( \frac{10 \cdot 75 \cdot 4 \cdot 30}{30000} \right) \cdot 8 \approx 2.40 \text{ pounds per month} \]

The salt usage is approximately 2.40 pounds per month.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ SU = \left( \frac{15 \cdot 60 \cdot 3 \cdot 30}{25000} \right) \cdot 8 \approx 6.91 \text{ pounds per month} \]

The salt usage is approximately 6.91 pounds per month.
