Water Softener Grains Per Pound Salt

For instance if we take water with 10 grains of hardness and run it thought a 15 lb regenerated 30k softener we could expect to get about 3000 gallon or about 200 gallons per pound of salt.

Water softener grains per pound salt.

For example a family of four uses 75 gallons of water each per day 300 gallons per day. The same goes if you use more water than an average family of four in one month. Contingent upon where a water test is performed this data will be accounted for in mg l milligrams per liter or gpg grains per gallon. If the hardness level of your water is above 10 grains per gallons then you will require more than a 40 pound bag of salt monthly or more than 10 pounds of salt per week.

What this means is a 32 000 grain capacity water softener will probably only deal with about 28 000 30 000 grains before regeneration is required. Water softener efficiency is a term generally used to rate a water softener by the relationship to its recovered capacity per pound of salt nacl used in regeneration. Softeners of old might be rated at 3 000 grains per pound gr lb. The efficiency of the softener can be simply described as the ratio of recovered capacity per pound of salt.

I know it sounds complicated but in essence it means how much of the resin the softener can recharge with one pound of salt. A water softener softening 75 gallons of water per day that has 10 grains of hardness per gallon will use 5 ounces of salt to remove the hardness accumulated per day. This of course is borne out in the typical rating of 24 000 grains on an eight pound per cubic foot setting. The consumer realizes upon receiving the softener that the most efficient settings are to use 6 pounds of salt per regeneration and to set the system capacity to 20 000 grains.

What does the grain capacity of a water softener mean. For residential application having up to 4 grains of hardness would still be considered soft water. How is the hardness of water measured. This is measured in grains so how many grains you can recover during the regeneration.

Jumping mg l by 17 1 will change it to gpg. A grain of water hardness is comparable to 1 7000th of a pound. One grain of hardness is equal to 1 7 000 pound of rock. Grains per gallon is the business standard approach for talking about water hardness.

Speaking of regeneration when you have to do a backwash on a water softener of this size you will need at least 30 36lbs of salt per cubic foot of resin. Sound a bit confusing. The rated capacity of a softener is the maximum number of grains of water hardness the unit can remove prior to regeneration. The hardness of water is measured in grains per gallon gpg.

So if your water softener needs to regenerate once per week you should only have to add one 40 pound bag of water softener salt per month.
