Water Softener Grains Per Pound Salt

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.

Water softener grains per pound salt.

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. 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. 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.

How is the hardness of water measured. 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. The rated capacity of a softener is the maximum number of grains of water hardness the unit can remove prior to regeneration. One grain of hardness is equal to 1 7 000 pound of rock.

For residential application having up to 4 grains of hardness would still be considered soft water. For example a family of four uses 75 gallons of water each per day 300 gallons per day. Softeners of old might be rated at 3 000 grains per pound gr lb. This of course is borne out in the typical rating of 24 000 grains on an eight pound per cubic foot setting.

A water softener will use approximately 1 pound of salt to remove 2 400 grains of hardness from its water softening resin. Jumping mg l by 17 1 will change it to gpg. 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. The hardness of water is measured in grains per gallon gpg.

The same goes if you use more water than an average family of four in one month. 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. This is measured in grains so how many grains you can recover during the regeneration. The consumer programs the softener to use 18 pounds of salt per regeneration and ends up spending much more money on salt than anticipated.

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. A grain of water hardness is comparable to 1 7000th of a pound. 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. Sound a bit confusing.
