K-Life is potassium chloride, which is a naturally occurring mineral and has been used for years as a salt alternative. K-LIFE and regular softener salt both soften water by a process called ion exchange, which means that as your water softener removes hardness and impurities from the water it must give something back to the softened water. With regular softener salt, sodium is added to soften the water. The harder the water, the more sodium is added. By using potassium chloride as a water softener regenerant, you can reduce the amount of sodium present in the effluent and replace it with potassium.
Potassium is less damaging to soils and less mobile than sodium.
Using K-LIFE to soften water in houses that have septic tanks and drainage systems is beneficial to the organic waste materials in the septic tank. Potassium is a nutrient required by the bacteria to aid in digestion of the organic materials. Overall, potassium chloride offers significant environmental advantages over sodium chloride when used as a water softener regenerant. K-LIFE can be used in any brand water softener unit. K-LIFE can be even added to softeners with regular softener salt still in them.
