Determine Water Softener Grain Capacity

This is because the softener is built with 1 0 cubic feet of resin.

Determine water softener grain capacity. If you think your daily water usage is higher set a higher value. To determine the appropriate water softener size for your home multiply the number of people in your home by the gallons of water they use each day 80 gallons per person is the average. In other words the softener will utilize salt efficiently up to 25 000 grains roughly and after this point the consumption of salt goes up disproportionately to regenerate the rest. In the example above the softener will be removing 3000 grains per day.

Use the calculator below and get a rough idea on the grain capacity required to sufficiently soften your water. Calculate softener capacity in grains ft3 resin x resin exchange capacity typically 30 000 grains ft3 grains. To explain this simply if you have a softener let s say with a capacity of 64 000 grains. Multiply the number of people in your family times 70 gallons of water used per day national average.

A softener is usually sized to regenerate about once per week. A 1 0 cubic foot quantity of resin can be regenerated with various differing amounts of salt to achieve different grain capacities. Select the number of people that live in your home. Multiply the answer by your water hardness in grains per gallon to convert mg l or ppm to grains divide by 17 1.

4 people x 75 gallons per day 300 gallons per day. Multiply that number by the grains of hardness in your water to figure out how many grains need to be removed each day. A 32 000 grain water softener is much more accurately described as a 1 0 cubic foot water softener. Daily softening requirement 10 grains per gallon x 300 gallons per day 3000 grains per day.

The softener capacity is calculated in three simple steps. Convert water hardness from ppm to grains per us gallon total hardness ppm total hardness gpg example. Usable softener resin capacity is 32 000 grains per ft 3 at 15 lbs per ft 3 salt charge the maximum flow rate for water softener resin is 7 gallons per minute per ft 3 softener is 65 full of resin beads if you do not know how hard your water is you can use this map to get a rough idea.
